Cloth/Skin Ripping/Tearing

[neilnafus]

I am creating an animation that involves a lot of skin and cloth ripping and tearing open (after bulging)and I am wonding if anyone happens to know if this can be done using the soft bodies or cloth dynamics, I havent been able to think of a way to handle rips that need to occur, any suggestions would be greatly appreciaed. Thanks in advance for your assistance.

honestly, I'd look into modeling in layers and composting the rip and changes between the different layers. So one modeled section that is complete , one with preset sections that are already cut and aniamte the sections comming apart. A composite would then change between the whole and the tear, and I think it would work well. Hope it helps, maybe you'll get some more ideas!

How about modeling the rips, turning them into cloth, hold them together with springs that will "tear" at a set spring tension?

I am still having issues with this, they cannot be blendshapes and the springs seem to always have a certain amount of give, is there anyway to get springs to be totally rigid and then disconnect, anyone have any suggestions?

The animations of the Hulk (from said movie) used the exact same technique described here. The clothes were modelled "pre-torn" and then connected together again by springs. When the springs reached a certain tension - they 'snapped' and the clothing tore.
