We are creating a FPS game and have a lot of level objects as you can see in the screenshot below. (With some highlighted colliders.) For the static colliders we used box colliders mostly but they aren't always as precise. Now since they are static objects how would the performance be if we used mesh colliders for these objects since they are static anyway? In a lot of topics I seem to read that it does have that much impact since the physics engine precalculates most of it see: http://forum.unity3d.com/threads/co...lliders-with-one-click-released.154361/page-1. Is this true? And if so could we just switch it all to mesh colliders for static objects?
