Companion Cavalry - Rigging

3/12/2014

0 Comments

 
For the last 2 months i've been rigging the characters ready for animation. This has been a very long and complex task for which I have needed to learn some new techniques and solve many problems to get the characters to work. I wanted to put in loads of detail for this part to bring the characters to life in the most realistic way with all bells and whistles turned on.
Picture
I decided to use the standard biped rig for both characters because this is a rig i'm familiar with, it is highly flexible and easy to use. After this project I am considering reusing the characters and rigging them up in maya which is one of the most used animation software in the games industry to expand my skill set and make me more employable.
Picture
To rig the cape I have been learning a bit about rope simulation to try and animate this part procedurally to save time. If I had to animate the cape by hand it would take me forever and I could never get it to flow like cloth. By using several chains of bones linked by constraints I will be able to focus on the character animation and bake this part afterwards. I did consider using cloth simulation but thought it would be more relevant to games if I used bones.
Picture
For the horse rig I needed to look at references for the anatomy of a horse to get this part right. Because it is a mammal and has all the same bones as a human, the biped can be used to rig this character by simply rotating and scaling the bones into the right position. I also swapped some of the geometry out for more horse like features to make it look more pleasing and match the horse mesh proportions better. Similar to the cape I set up the reins using a chain of bones linked together that will be procedurally generated.
Picture
For the rope simulation to interact correctly with the characters I have needed to cut up and position collision boxes that are attached to the individual bones so that reins and cape have something to bounce off of when physics is applied.
Picture
What has taken the vast majority of my time to rig has been the face. This is a highly complicated bone rig predominantly set up using position and rotation constraints referencing point helpers. Each shape the face can create is saved out with a list of position and rotation constraints linked to a GUI using reaction manager. The bones and helpers are set up in a hierarchy with a root bone linked to the biped head. Furthermore, I have designed this rig to be scalable, with each bone and helper editable so that it can be skinned to another mesh. Because the animation is saved in the GUI, it can be transferred from one mesh to another by saving out an XML file. I don't plan on testing this out for this project but next time I do an animation project in 3dsmax I will reuse this rig to save time.
Picture
The rig can produce many different facial expressions and lip shapes by combining the GUI controls. Aswell as all the main vismemes that Jason Osipa describes in his book Stop Staring, it is also capable of making basic expressions that will I will be incorporating into my animation to give the human more personality. I am also considering finding an appropriate audio clip that can demonstrate this rig more effectively in my showreel.


Finally, I have been testing out lighting in 3dsmax. I want my showreel to really stand out and display my work at a high quality so I am prepared to spend some time rendering out quality lighting after I finish animation. This video demonstrates ambient occlusion using the light tracer, with the character performing some of the test poses I have been using to skin the mesh to the rig.

I now plan to spend the next 2 months animating both characters together in a range of different scenarios. I need to put in the most effort for this part as I am an animator, this is my chief skill and needs to be at a high standard. I expect to finish the project towards the end of May.

Companion Cavalry - Texturing

1/20/2014

0 Comments

 
This week i've been pushing on with getting the characters uv unwrapped and textured by transfer mapping the materials from zbrush using the middleware package xNormal. Texturing is one of the areas I am not as practised at and haven't done very much of for several years, so this was a chance to refresh my memory and work out the appropriate pipeline to get the poly paint information from zbrush into 3dsmax.
Picture
In retrospect, one mistake I realised I made whilst working on the human was that I probably should have consolidated all the separate parts into as few texture maps as possible to save memory and keep things stream lined. Instead what I did is texture each bit individually one by one as I brought them into max. This wasn't so much of an issue to begin with as I only had 5 maps to apply, but when I started to add specular and normal maps I realised that 15 textures was probably a bit to much for one character model. Even though I designed the character to have interchangeable clothing that I can customise later, these would still most likely use a texture atlas to save space so this is something I will need to keep in mind next time I do a similar character.
Picture
Luckily because the horse doesn't have many overlapping items of clothing I was able to use a single UV map to texture this model. For quite a few of the meshes I found that after I had unwrapped and exported them I needed to go back into zbrush to rescale the final mesh to the sculpt. Somehow the pivot point had gone astray in zbrush and the meshes were not sitting inside each other anymore, so a few textures are a little bit bodged on and needed some clean up in photoshop to readjust parts.
Picture
With the texture maps created they all needed cleaning up in photoshop to remove errors and get the best result when rendered in max. This involved colour correction to make the skin on both the human and horse more natural and the right level of brightness. From xNormal I baked out cavity and ambient occlusion maps to apply in photoshop as extra bits of dirt and grime that made the diffuse stand out a bit more. I also needed to smudge the edges of the maps in certain places where the poly paint hadn't quite transfered properly onto the uvs. This process was mostly iterative, checking the models by rendering in 3dsmax before quickly updating things in photoshop.
Picture
The final thing to model and texture were the eyes and mouth for the human which needed to be made from scratch. I have been considering close up shots of the character doing facial expressions and possible some lip sync for my showreel to bring that character to life so this area needed lots of detail to give a realistic result.

Huzzah! That is the halfway point for this project done, I now have the most important assets for my showreel produced with the exception of a sword and spear that will be needed for combat moves. I expect I will use placeholders for them when I get animating and texture them towards the end. For now I need to crack on with rigging!

Companion Cavalry - Retopologising

1/10/2014

0 Comments

 
To start the process of getting the character game ready and suitable for animation I have been retopologising the horse and human to create a low res mesh that can be textured and rigged. This involves drawing verts onto the sculpt to layout the polygons in the best possible shape that matches the original character. It takes a very long time and I have had to make sure that the topology has edge loops around the joints that will allow the mesh to realistically deform for animation. 
Picture
Here are the two finished meshes for both the horse and human in 3dsmax ready to be textured. In the end the human came to 7000 polys and horse 5000 polys, which are quite high res for a game characters and I may need to consider cutting that down if I end up sticking them in an engine. For my portfolio that doesn't matter as much as I will be focusing on a quality animation result. However I have tried to keep the poly count at a reasonable level as it will slow me down if I have to rig the characters with ridiculous amounts of detail.
Picture
Part of the reason why the human is so high res is because I have been producing each of the parts separately to give me more options. The naked character was done first as a base for the clothes in case I decide to do some combat animations that will need enemies to fight. Because they will share the same rig it wont take long to simply reuse the naked version and get a few more different characters to animate.
Picture
The naked human took the longest to do because there were many fiddly areas that need lots of resolution for them to be animated. These include the fingers and face which need edge loops that allow for the many complex shapes these parts can create.
Picture
I decided to group all the torso clothing into one piece to simplify the mesh in this area. I expect that I will delete a lot of the geometry on the naked human underneath this to reduce any clipping that occurs when the rig deforms.
Picture
Working out the topology on the horse was a bit experimental because I have never animated one before and can't quite expect how the mesh will deform. To help me figure out edge flow I took a look at Edward Muybridge's work on animal movement and the way a horse moves. This helped me understand where the main movements would be coming from and how the joints will need to squash and stretch when animated.
Picture
I am a bit behind where I wanted to be by this point, mostly because I've been busy with my job over christmas. I do have a lot more time now though and I will be able to pick up the pace a bit. In two weeks time I plan to have both characters UV unwrapped and textured with diffuse, specular and normals. Once the characters are fully complete inside 3dsmax I can start rigging them up and getting them ready for animation.

Companion Cavalry - Sculpting the Horse

11/30/2013

I have now completed the horse to a level where I think it is ready to be retopologised. This part didn't take as long as the human to do, partly because I didn't have as many complicated clothes to produce and also because there aren't as many fiddly bits like fingers and facial features which need to be just right to prevent them from looking uncanny.
Picture
I decided to go for a blackish brown breed of horse called Andravida which originated in the plains of greece and therefore could be one of the breeds used by the companions. I also liked the colour and think it will go well with the human when I get them both into the same scene. 
Picture
There were very few references for what sort of saddle and straps would be used on the horse so I mostly took inspiration from the film Alexander (2004) when it came to designing this part. I also embellieshed them with items of jewellery based on ancient greek icons and symbols. It is most likely these wont be seen close up but they will provide detail and make it look more interesting.
Picture
When modelling the template I made sure I scaled it correctly against the human template so they both match when I export them out of zbrush. I expect I will be able to make minor adjustments when they are together if I need to.
Picture
What I am now most concerned with is making sure the lengths of the limbs are correct and everything is proportionate. I dont want to find out later when I start rigging that something is off otherwise I may have to stretch the texture to get it right, better to sort it now.

For the next month my plan is to retopologise both characters and get them into 3dsmax to be UV unwrapped. I will then be able to produce texture maps which will include diffuse, specular and normals that will need to be tweaked in photoshop to get right. Hopefully I will also be able to begin building the rigs though I dont know if I will have enough time to get that far.

Right now though I will review both of the characters and add small things I've noticed I need to change and anything people point out through feedback.

Companion Cavalry - Clothing, Polypainting

11/6/2013

0 Comments

 
The zbrush sculpt for the Foot Companion is just about done. I've been putting a lot of effort into this to get the naked sculpt as anatomically correct as possible, as well as extracting armour and clothing that needed to be detailed enough to look realistic. I then poly painted everything and experimented with textures to bring the character to life.
Picture
Apart from the cloak the entire character was sculpted symmetrically to save time and make it easier to game res later on. Whilst I have been loosely following historical reference I tended to veer towards what looked best rather than making sure everything is historically accurate. 
Picture
His armour is designed to look like hammered bronze and includes a Muscle Cuirass, which only the most wealthy of nobles would be able to afford, and the Boetian Helmet which was just coming into fashion at the time and was preferred over other helmets like the Phrygian because it offered more protection to the face and shoulders. The horse tail crown is thought to represent a senior cavalry troopers rank.
Picture
Since last time i've been improving the anatomy slightly based on feedback, especially around the face which people said looked a bit uncanny. I've also painted in skin tones, first starting with a red base coat and then painting in white and orange colour's to give the fleshy appearance of skin
Picture
The face and hair is only semi realistic but i'm not too bothered with vast amounts of detail since the final character will be game resolution. I'm not very happy with the hair because it leaves a harsh line on the forehead but I think this wont matter too much because it is mostly obscured by the helmet.
The next job for this character is to start retopologising which I have found laborious in the past using the standard tools in zbrush. I am considering looking at Topogun which I've heard is better. I will leave that for now however and focus on sculpting the horse which I expect to have done much quicker than the human. I do now have a job to help pay the bills so I wont have as much time to work on this as before, though this will hopefully motivate me to work more in the evenings and should sustain me until the project is completed.

Companion Cavalry - Male Template

10/15/2013

0 Comments

 
For the past 2 weeks I have been modelling and sculpting the male template with correct proportions and human anatomy for me to start adding clothes and details. Having had previous experience in zbrush doing a character sculpt I decided to create the basemesh in 3dsmax rather than using the z-sphere tool. This was so I could control the key forms better and make sure I had enough resolution and edge loops where I needed them in places like the hands and face which can be tricky to sculpt from scratch in zbrush. 
Picture
Using the photoshop template I made earlier and some photo reference I blocked out the character, starting with a cube to create the torso and extruding all the limbs from that.
Picture
I made sure I had included a lot of the small details like the fingers, ear, nose and toes and get them roughly in the right shape and position to minimise any pain in zbrush so I could focus on sculpting the anatomy on top rather than getting the basic form right.
Picture
Here is the final sculpt of the (mostly) anatomically correct human male. Pretty much your standard muscly well built guy but this is what I would imagine from a well trained solider so no need for fancy proportions. I could probably keep going with the anatomy indefinitely to make it 100% realistic but I dont want to be working on it for ever so close enough will do.
Picture
Mostly using myself as reference, (probably not quite as toned). The hand was a pain in the arse to do to get all the fingers the right length with nobbly bits so they can bend in the right place. I did forget to put some geometry in between the base of the fingers which has resulted in an ugly crease. Hopefully I can smooth that out in photoshop when I texture map the low res version.
Picture
The toes were definitely the hardest part to do because they're so close together and I expect I may have issues normal mapping those which will again need to be smoothed over in photoshop.
Picture
The head is a little bit feminine and will need more work though hopefully a bit of stubble will sort that out.

I will most likely continue to tweak a few things because I start poly painting but I need to get a move on with that so I can add clothes. Now that the anatomy is done the hard part is out of the way and I dont have to be quite as accurate with the clothes it should all come together quite fast now. I would like to experiment with several different clothing and armour types to see which one I like the most but I still plan to finish off the first character by november so I will have my work cut out for the next few weeks.
Picture
On a side note, i've also grabbed a copy of this book which has loads of really useful historical references of armour and clothes of the companions, as well as descriptions of fighting behaviours and techniques which might come in useful when I start animation.

Companion Cavalry - Concept Art, Design

9/30/2013

0 Comments

 
To design the character I have been developing some concept art over the past few weeks to experiment with different clothing variations and colours to create usable templates of the horse and rider that I will be able to start modelling from. I had intended to do a 3/4 view concept piece but felt this wasn't as necessary to the project because it would provide far more inspiration developing multiple ideas than focusing on one. 
Picture
Because i'm creating a real world character my concepts are very limited because I need to ensure a level of historical accuracy and make sure that it is authentic. Therefore I have been collecting as many examples of greek armour and clothing as I could from the internet to get a feel for the style of clothing they wore. I have found there are an enormous amount of variations in helmet design and armour though the main reoccurring themes are that greek soldiers mostly wore a corslet chest piece, skirt and loose overalls, an open faced helmet, sandals and a guard for the shins. The best reference for the companions was a sculpture on the Alexander Sarcophagus which showed them carrying a spear and wearing a cloak. 
Picture
To speed things up and prevent me from having to work out anatomy over and over I decided to create a realistic template of the character, drawn from photo reference. This allowed me to focus on trying out different clothing variations by reusing the same template. These are several different designs from the same period though I think the bottom middle and right are more closely related to the description of the companions so I will most likely develop the character with those in mind.
Picture
I've also created a template for the horse for which there were far fewer references. These are several ideas drawn mostly from the film Alexnder the Great (2004). I looked at the different breeds of horse to experiment with colours and how that might fit with the saddle design and rider.

Now I've finished my templates I can start work on the model of the rider. I intend to block the character out in 3dsmax to begin with as I find it far faster to sort out overall proportions using box modelling software. Once I have something i'm happy with I will then move into zbrush, smooth over the anatomy and start adding the clothes. I hope in 1 months time to have completed the first character.

Companion Cavalry - Ideas, Sketches and Research

9/13/2013

For my next project I have decided to start work on a quality animation piece that will demonstrate the skills I have developed over the last 5 years at college and university. This piece will be more ambitious than anything I have attempted before and I hope will give me the portfolio I need to get my first job in the games industry. My hope is that I can create a piece that shows how flexible my abilities are in producing game ready characters and will open the door to multiple animation job opportunities. 

Philip II of Macedon

Macedonia was a hellenic kingdom situated in the fertile coastal planes of northern greece. In the ancient world it was one of a number rival greek states that existed before the rise of the Roman Empire. Whilst being the largest of the greek states, it was for many years kept weak by internal struggles of the noble families, raids from barbarians to the north and the meddling of other states such as Athens. If it could break free of its situation it had potential to become a great power because of its large population and access to horses which were more readily available in the fields of the north.

It was Philip the second who finally managed to achieve this objective. In a time of shifting powers when the other major greek states were weak, Philip managed to unify Macedonia through diplomacy, bribery and an increased importance in the military. Within a year of his succession he had managed to raise an army of ten thousand and begun a radical re-organisation of how it trained and fought. This had the effect of stabilising the country because now the peasants loyalty to the nobles was weakened as they were now directly serving the king. The nobles themselves were bound to the king by becoming the kings 'Companions', and their superior cavalry were put to good use as the royal bodyguard. All these changes turned Macedonia into a highly efficient armed state, allowing it to secure its borders and force treaties with the other greek factions.

Ultimately it was Philips legacy that enabled his son Alexander the Great to carve his way into the history books as he led the Macedonian army to conquer the Persian Empire.

Companion Cavalry

For my project I have decided to recreate one of the Companion Cavalry, the royal bodyguards of Philip and Alexander. This will be a thorough and detailed project where I will design and produce the character and horse suitable for a game engine. I will then rig and animate the character doing several hand keyed loops that could be imported to an engine to create a playable character. I also hope to obtain motion capture data and apply it to the rig to demonstrate those skills to potential employers. Finally I will render the piece out using quality lighting and sounds for a short, high quality animation piece.

Here are some ideas and sketches i've been preparing to help me design the character.

My plan for the next few weeks is to create a high quality concept piece of how I want the character look and feel when animated as well as Front, Back and Side drawings to plan out the model.
