Creating a collision with an hole

[yoshy]

I need to create a collision form that has a hole, kind like a donut. I was thinking in using convex hull, but that ignores the inner points. Another alternative is to fuse several collision shapes, but it doesn't seems very elegant. Does someone knows a way of doing that? creating a collision form that has the shape of a donut?

Thanks in advance!!

There in the forum a topic about that.

It was posted a link to a code that convert any mesh into a set of convex collision, and then you can use them to create a set of convexhulls.

That seems great. But I have made some search on the forum and haven't found anything about the subject. Does anyone knows where I can get that code?

you just create convex hull pieces and make a compound collision from them using NewtonCreateCompoundCollision .
