Apparently, you can now move static 3D colliders in Unity 5 without performance penalties (at least in terms of framerate). Unfortunately, the Profiler still spams the following warning if I do so: So, is that indication that the feature is non-existent or is something messed up? Or should I just ignore it and move on? I didn't notice any serious performance issues caused by physics anyway, so I guess it's working as intended. I just wonder if I should still keep getting that message. Maybe that's just a remnant from older versions of Unity which should be removed soon. Or maybe I missed something in the docs.
Hello from October. I just spent some time researching colliders without rigidbodies (and how they're automatically flagged as static) since my Profiler was giving the same message you pasted. Just to underline that the warning is still present and confusing, given the apparent PhysX update obsoleting (maybe?) the problem.
..and hello from 2016! Just noticed this warning, even though I was under the impression moving colliders without rigid bodies doesn't matter anymore since Unity 5.0.
