[solved] Sound shooting / walking on staticmesh

[Crozz]

EDIT: Found it.. in the material editor u can set PhysMaterial:)

I changed the material on some stairs to something more metallic looking, but the stairs still sounds like wood when I shoot it.. It also get ember marks on it.
Where do I go to set it up so that it sparks and sounds like metal when shot?
