Hasta La Motion!

the dragon is modelled and rigged… I get an obj and mdd from from the animators so I can do the sim in maya.

the problem I am having is that because the wing is double sided (thick fleshy wings) im getting a huge amount of penetration between the top and bottom membranes.

I first tried simming a single sided polygon which lay between the top and bottom layers and then constraining the top and bottom layers to the simmed mesh, this worked to some extent but as soon as the dragon folds its wings up im still getting penetrations.

the next thing i tried was to make the entire dragon ncloth and then paint an input attract so that only the wings segments simmed.
turning on self collisions stopped most of the penetrations but still the wings freak out and collide as soon as it folds up its wings.

does anyone know the correct workflow for something like this ive been looking around for info online and cannot seem to find anything helpfull.

how did they do "how to train your dragon" ? or harry potter dragons
i guess its specfically written software…dunno

help ! im pulling my hair out here !
