Hello,
I am trying to import a mesh with custom UCX collision. When imported, only a handful of the thirty or so volumes have imported. I’ve checked the naming and ensured that they are all in the export. Any idea what causes some UCX meshes to import, and others to not?
If you are absolutely sure that they have been named properly and that both the mesh and collision was selected during the exporting process, I suggest looking at the import tool. The import tool allows you to ignore a collision on import.
It’s been awhile, but I think I was able to narrow it down to the simple fact that the collision volumes weren’t triangulating correctly when imported. I notice that depending on the setting in UE4 mesh import for collision imports (one convex hull per UCX or not) that the range of geometry that the importer can handle seems to vary. Easily triangulated meshes such as simple cubes and prisms are the most reliable. If the mesh is more complex than that, there seems to be a chance that it doesn’t triangulate correctly, and isn’t imported.
