Best way to detect ceiling when uncrouching

[Salepate]

I had to implement custom crouch for some reasons and now the pawn can uncrouch even when he's not supposed to, (either because there is bsp or a static mesh right above him). I wondered what was the best way to detect such case. Would a trace be honest?

Trace is probably your best bet. Not much of any other way to find out if something is in your way.
