Hello, all!

How correct mesh generation? I have some points (of triangles) and I want generation meshes with collision.

UCustomMesh generation only visual component.

UProceduralMeshComponent mast generation meshes with collision, but the don do it. I use this tutorial:

The last parameter to `CreateMeshSection` is `bCreateCollision`. You need to set it to `true` instead of to `false` for collisions to work.

Keep in mind that there is a big performance penalty for using it. I think the optimal way to do it is to make a second invisible procedural mesh with less polygons that envelopes the first procedural mesh and enable collisions on it.
