Bug in btGImpactQuantizedBvh::refit function with scaling the mesh #4588

Open kochol opened 6 months ago

I have a program that uses btGImpactMeshShape to create a mesh shape and when I scale it the collision detection won't work anymore.

But when I remove the below if and call the m_box_set.buildSet() function everything works as expected.

I think the bug is in the below function.
