I have a blueprint system for some procedural roads, in editor everything works as expected, road manager spawns road anchors, road anchors spawn roads, roads have a spline and finally roads spawn a spline mesh to follow. In editor collision is set to complex as simple and everything seems perfectly fine, physics interactions are complete and normal.
However in a packaged build spline mesh components have no collision. Checking with the show collision command shows no collisions either.
Collision settings are set in both the static mesh itself and in the blueprint spawning them.
What do I do about this?
