Hi there,
I have a scene with an nCloth that has tearable surfaces, and would like to use motion blur.
The render crashes on the frame the tearing begins. Regardless if I use rendered motion blur or a motion vector pass.
I've read in a post by Duncan that topology change (as in tearable surfaces) is a problem for motion blur...
Does that mean I can't make motion blur in this scene, or is there a way to solve this?

Thanks a lot,
Gabriel

Some SOuP may help you: http://soup-dev.com/examples.html and search for " How to render changing point count geometry with proper motion blur? "

good luck

Thanks for the link.
I tried it, but it's terribly complicated and really like fumbling in the dark.
I will keep investigating it, and see if I can get it to work.

I found another solution - baking the ncloth (with amShapeBaker). This way the vertex count is kept fixed and vectors turn out well.
