In demosSandbox convexApproximation.cpp, Line 37 -- Assertion failed.

In coreLibrary_300\source\meshUtil\dgMeshEffect3.cpp, Line 1354, The dgMeshEffect::CreateConvexApproximation function returns 0! The original code is commented out. So its not NewtonCreateCompoundCollisionFromMesh the function that bugs, but the NewtonMeshApproximateConvexDecomposition

ha, yes I was going to make an improvement on that, and I got distracted.
are you using convex approximation now?

I see if I can get it back on soon.

No, I'm not using it now, just testing :) Take as much time as you need because it's your project, and it's already at its best :twisted:

ok I fixed that commnet out error.

Tha was because I change the format of teh report progress call back,
and I did not want to spend teh tiem refactong that call so I put and assert and return NULL
Then I forget to fix it.
sorry abput that.
It should be fine fine now, please try again

There's only one little thing. The convex approximation is calculated improperly for the cylindrical cups:
