I placed a few rocks on my level, scaled them non-uniformly, rebuilt level (geometry and lighting) and yet player can walk through the rocks 
I can see there is collision primitive when inspecting rock mesh in the Static Mesh Editor, but collisions arenât working.
Any ideas whatâs going on ?
Thanks
Hit ALT+C in the viewport to see collisions, just to make sure theyâre actually there.
If they are there in the level, it is prob the collision channel that the rocks/player capsule is set to. I would look at that, it will prob solve your problem.
Thanks, will check it out.
Alright, solve the issue. My player spawns on one place, then itâs being teleported to the desert. For whatever reason teleport destination point was high above the ground. When player got there, it didnât drop down to the ground for unknown reason. So when I would âwalkâ, Iâd walk in the air above my rocks (I donât know how I didnât notice that view is is unusually higher above the ground :o ). Surprisingly player would follow terrainâs curvature while âwalkingâ in the air!
Moving teleport destination down to the ground âfixedâ it - player walk on the ground and collides with rocks.
