To avoid any concern for this Soft Body Character Physics request, this request is from Game Arts Cafe, my implementation is here https://www.youtube.com/watch?v=wAby9mfjUv0 I have only added a reference to the Unity Asset Developer Obi to explain a more ideal type of collider to use for cloth than the collision shape system that currently exists in iClone. The reason is to add better interaction between other soft & ridged bodies and I mentioned that it would be good for both Reallusion and Obi to create compatibility so characters coming from iClone or Character creator will work in Unity with Obi since there is nothing that I know of that will work automatically using iClone's Physics textures. Customizable collider resolution should be available for Rigid bodies and characters with soft body physics in my opinion should have an evenly distributed grid based particle collider solution that aligns to the Character's normals *per material* (to control performance like disable material colliders except for one material) in the physics weight map area.

It would likely ideal if you had people in the game industry making a Character physics system with accurate functional collisions. When I went to check on Obi's progress recently I found out they are making a softbody character system https://www.youtube.com/watch?v=9Tdmplqc_3U I think overall that you could partner with Obi for the Unity side so they get customers from you that could setup their character with physics easily. I've used their assets before and it wasn't so easy to setup but the simplicity could potentially be setup on your side and just work properly in Unity but also to understand proper collision setup to work in iClone making film etc. Currently from what I've created with the softbody physics in iClone is more realistic than Obi as I can get flexible details on particular wrinkles with physics texture painting.
Update on testing with physical interaction. I was getting crashes with Cloth on cloth enabled with one character punching the other but it seems like it might have been either large texture size one character was using or has an issue with the shader itself (even though it crashed in minimal mode, it did not crash setting the character render to smooth shading in the scene view.) I did experiment adding collision shapes to the belly area, it does add more influence but maybe it's the wrong collider type, size and position. In Unity, there is an asset that uses particles as colliders (Obi cloth) and users can set the distribution like a grid and collider amount. I know soft cloth has a collider limit warning and ideally an even distribution and amount should be setup in the physics texture material so that colliders can be seen as dots overlaying the material.
Object Interaction Tests With Soft Cloth Applied To Character It's known in Unity at least that increasing collider resolution helps soft cloth interactions. The only progress I've made so far for character & object interaction is to convert an object to self mesh to get more resolution. In order for quality interaction between cloth and rigid bodies, I hope you add more resolution and consider that because iClone is not a game engine, please allow higher resolution/accuracy for film. My particular settings are: character soft vs rigid margin = 4.0 solver frequency=400 Dampening .30 Drag= .10 Tether=1.0 Elasticity=88 Stretch=17 Bending=67 Inertia=2
