I just made a quick test with new plugin (on Windows 7) and found that for several object the “Shape Type: Convex” generates completely wrong shapes:
-a capsules and spheres gets a small box (I know I should not use these types here, but still)
-a cylinder/tubes seems sometimes correct but can get a bar or plain
I hope you can fix this.
By the way: I could not find the 3.4 SDK on GitHub. Should I enrol for PhysX GRB Beta for this?
