Hello
I am trying to understand why my character falls though my boxes while it don’t fall through the plane. Two of the boxes have different scales. I feel that its something basic that’s missing or some ECS logic that i am not considering in my physics setup. No errors or warnings so i am kind of lost were i should start debugging. I might suspect the parameter CollidesWith in the RaycastInput, because i don’t understand why i need to select physics layer with bitshifting.
I am thankful for any advise.
