Line Trace on Skeletal Mesh

Hi,

I’m having an issue where my line traces aren’t hitting the pawn’s skeletal mesh. If i enable ‘Enable Per Poly Collision’ on the mesh it does register a hit but I’m then unable to simulate physics (comes up with error)

Any help with this one would be greatly appreciated.

Don’t worry, Once again I’m stupid. I had enable per poly collision turned on also on the mesh in my character BP. must negate each other?
