When my player goes onto some curved part of a mesh/model, it falls. Here is a part of the model rendered in SketchUp;
At the start/bottom of the loop, the player suddenly falls. The same thing happens to other models.
The mesh is a whole model that has a mesh collider. Straight surfaces seem to work but any surface which is in a different angle doesn’t work.
I’ve edited it but I think they’re non-obtrusive additions.
I’d be so grateful for anybody who finds an answer.
