Footsteps

I have been busy for the last few weeks so I only saw your reply now. I haven’t tried this yet but I will tonight. Any idea how I could have different sounding footsteps. One for grass one for wood and so on. I know how to set up the materials for different sounds but again that only works when an object physically touches the material not for a vr pawn. Someone said setting up a line trace but how would you get that to work with your bp?
