The collisions for the weathered rock items don’t match completely with the actual models, so there’s a lot of spots where, if they’re scaled up, you can stick your head into the rocks or you’ll get stopped before you’re actually touching them.
I know they’re probably just like this since the rocks are tiny to start with, but I use them scaled up a lot for making natural scenes where the inaccurate collisions are a lot more noticeable. Maybe the collisions could change depending on how much the rocks are scaled up, if possible?
