I know it's a stupid question but - how can I make my FPS controller collide with rocks I add from "paint details"?

I'm using the stone detail mesh that comes with the demo terrain assets - I did check "generate collide on both "RockDeatilMesh" and "RockMesh" but I still cannot collide. How can I fix that?

It's the FPS Controller that comes with the standard assets, I haven't modified anything. The game will be from the 3rd person perspective, but we just started so we're using the FPS controller to walk around the map, see what we've done so far.

Yesterday I managed to make the rocks collide with the FPS Controller, but I forgot how.

Detail meshes won't generate collisions. What you could do is to add CapsuleColliders to your Rocks, and add them as Trees instead of as detail meshes, that should work.
