What is better for collisions. Multiple simple. Or fewer complex

id like to get some peoples opions. when setting up collisions on complex items. what is best. fewer more complex collisions. or several smaller simpler collisions

I’m just guessing, but I’d think that whatever method has the fewest faces will have the lowest performance cost.

Id love to assume that also but ive been told that the simple spheres cost the least and i dont have any other info to go on

Whichever is the best between what you want vs performance.

But what is that factor of performance. Ill be working on my assets soon and ill gladly make my meshes either way. But what is less stressful on the engine. A bunch of simple collisions on one object or a big complex of about the same vertex count.
