Hulkey Muscle Rig WIP 1

Done with the back muscles. Still some smoothing to be done, but just want to put these 2 side by side, with & without muscles to see the effects.

Hulkey Muscle Flex Test

Decided to play around with Hulkey again. Always wanted to play around with muscles more so decided to put some into him to see how much more can I push the deformations.

Built the skeletal structure using NURBS spheres. Similar to the one in Autodesk Hyper-Realistic series. Played around with rigging up the scapulas, and pretty happy with the results. Managed to achieve a little "sliding around the rib-cage" effect. I will put up a video on that later.

Muscles built using a simple muscle plugin with 4 attachment points and volume preservation.

This is the test to make sure no muscles flip during motion, before I even start skinning them:

Next up, the skin deformation itself.

Nice Hulkey Pose!

Really love this pose by Edward. AWESOME!

Also revealed some deformations to be fixed when I looked at the scene. :P

Hulkey Walk Cycle Test

A test by my animator friend. Thanks Barry!

Hulkey's all done!

Of course, still pending feedback and comments from my animator friends. Probably some bug requests as well haha.

Added various deformations using the poseDeformer plugin, still my trusted tool with regards to shape fixes. Shapes are sculpted mostly, but I did setup a separate rig with Maya Muscle skin system to provide the base of deformations. Took a short time to setup, but got really good results with it. Using that, shapes are duplicated off the geometry, and used as target shapes in the poseDeformer nodes. Simple and easy, yet the results are great and the rig still remained fast enough for Animation.

I'll probably compile a whole list of Hulkey's features as well as demos, but for now, I'll just leave you with a fun pose of him. :)

Hulkey Facial Rig Done!

Finally done with the facial blendshapes, hooking up to the facial GUI, and added the on-face controls for additional animation tweaks. Rig's getting slower though. Will spend some time to optimize it further, IF I have that time haha...

Next up, deformation tweaks for the body. GRRRRR!

Hulkey Anim Rig Done!

Completed all I wanted to do with Hulkey's animation rig. Ability to do no-pop IK FK switching and dynamic parenting is now implemented as a right-click pop-up menu instead of a separate character UI like I did for the beast.

I will be doing some feature demos later, but for now, here's the basic skinning deformation tests for Hulkey. You can click on youtube directly to see a higher res version. I believe the key to good deformations always start with good basic skinning before you can add on any other deformation features.

Hulkey Anim Rig WIP

Basic skinning all done. Still need to add some space switching elements before handing it off to any animators who might wanna try playing with it.

Hulkey Body Modeling Done!

Think I will call this done for now. Don't wanna go overly detailed too since Hulkey is supposed to be cartoony. Sculpted his arms, legs and torso to define the shape and form of the musculature of the body without adding too much details. Now rigging can start! :)

Hulkey Body Modeling WIP 2

Defined the shoulders and back more now. Added in the actual head now plus the base mesh of the hands. Played around with the size of the head and I find that this looks best. What do you think?

Next will be adding the toes and giving the rest of the body more definition.

Hulkey Body Modeling WIP 1

Super busy recently at work. Only managed to scrap a little time at night. Body so far...

Hulkey Face Modeling Done!

Took a longer time than expected. After evaluating it further, I had to rework the face topology. Finally done with gums, teeth & hair as well. Gonna stick to this resolution for now to see how much deformation I can achieve before deciding to upRes it (which I'm guessing I probably will need to).

Just a note on my workflow. I am still planning to go with the joint-based facial setup, but first, I will be modeling all the defined shapes, and then match up the performance of the joint-based facial setup to achieve the modeled shapes. This is to emulate the actual production situation whereby all the facial setups of the character have to be "in-model", that is, approved and defined by the director (That is the reason why most production facial setups are still blendshape-based). To summarise:

1. Joint-based facial setup to simulate "skin-sliding" effect of the controls
2. Model actual blendshape targets to define the look and feel of the character
3. Make use of the blendshape targets as additional corrective shapes of the facial setup

Next step: Rough blocking of the body. Just wanted to roughly define the shape of the shoulders and neck first to lock down my face geometry.

Hulkey Face Modeling WIP 3

Left to right: Smoothed version, Base Mesh

Face more or less done. Gonna model the ears, inside of the mouth and hair now. Probably going to do some facial rigging tests to test the topology before moving on to the body.

Hulkey Face Modeling WIP 2

Defined basic edge loop flow in the face.

Hulkey Face Modeling WIP 1

Just defined the basic shape of the head.

Final Hulkey Design

Think this is more or less what I want now, thanks to comments from all my friends:

Tweaked the proportions a little: Made the head smaller to make the body feel larger, less blocky legs, maintained the blocky hands and feet, a little more curvy now instead of the totally box-like figure before, and legs are now shorter compared to the body.

Next up, face modeling.

Still exploring Hulkey designs...

Hmmm due to comments from a friend, still continuing to explore the shape and proportion of Hulkey. Comment was that the one I had before is too blocky, which is kinda true as well.

If I wanna go cartoony, might as well try and experiment more. Here goes:

Face model sheet with some test expressions

Somehow Hulkey doesn't look too good with any other expressions except being angry. :)

Hulkey body model sheet up

Not very well done, but at least something to start with. :)
