For all the large rocks that make up the world on my map, I don’t import collision meshes for them. I instead uncheck these boxes under the mesh collision settings:
UseSimpleBoxCollision = False UseSimpleLineCollision = False UseSimpleRigidBodyCollision = False
I have thousands of these rocks on my map, each with around ~4000 poly’s.
These rocks don’t seem to have any performance cost. If I delete them, I barely notice any difference in performance.
I have always assumed that importing low-poly collision meshes was important for performance, so I’ve never understood how all these rocks perform so well.
Can anyone give any insight on what the actual cost of collision is?
