I'm trying to achieve a specular highlight on my rock face, not going for strict realism but something of a wet look. I plug in a reflective shader both on its own and separately as a part of a default shader and am not getting the desired results. Either nothing happens at all (visibly) or the rock face goes completely black. Any ideas? Is there a best way to set this up,or any non intuitive settings I should be using? I'll post some tgc's later if I cant find a solution.
Thanks in advance
Richard
