V-HACD crashes

Post by alanzjl » 10 Sep 2019, 16:33

Hi,

It seems every time I try to do convex decomp with V-HACD VREP will crash. HACD works fine. I tested in both OS X and Ubuntu 16.04. Output in console is

Code: Select all

Computing the convex decomposition (VHACD)...

Hello Alan,

we are aware that the V-HACD can crash depending on the settings and/or the provided shape. From what we could see, the problem lies directly in the V-HACD library, which we didn't develop.
Did you try to use an updated version of the library in the v_repExtConvexDecompose plugin?

Cheers
