We’re having a problem where static meshes imported into Physx Lab 184.108.40.206, fractured, then exported as a .apb file and imported into Unreal 4.14.3 or higher results in the destructible mesh having inverted normals.
We’ve tried just about everything regarding FBX versions or OBJ but get the same results.
If the same static mesh is converted to a destructible mesh in UE4, the problem does not exhibit itself. However, we need to use Physx Lab since it’s the only way to generate multiple depths of destruction fracturing on the model. Here’s a screenshot of an asset with this problem - http://pasteboard.co/HybZqc1sw.jpg
Any help would be appreciated.
