Fracture Mesh Error
Hi, I'm having an issue with fracturing meshes in Unreal with the built-in destructible mesh generator.
at preview depth 0, it looks fine
at preview depth 1, the textures break.
you can see that the holes in the mesh are not generated with any sort of relativity to the mesh, textures, or fractures
you can also see that the mesh on the inside gets all sorts of fun, unexplained holes. .
If anybody has any suggestions for how I might be able to fix this, my team and I would be most grateful for any tips or help.

When you are making a destructible you need to make sure that your mesh is fully enclosed. There cannot be any open faces as the voronoi fracture method or even the methods in PhysX Labs will not generate faces for parts of a mesh that is not closed.
That would be the first place to check. After you do that if you still have any issues please let me know and I will be glad to offer some assistance.

I think the best solution for you would be to get a hold of a copy of the Nvidia Apex Lab and then use it with some custom fracture maps to get it set up the way you want.
If that doesn't work, you're going to have to split your mesh into smaller, seperate objects. It is pretty silly, but there really isn't an alternative.
