create a simple room and insert your wanted shaders - see if they all act as they should.
try moving around the shaders and look for duplicate faces that use the same shader.
try replacing the blue with red just to see if the glow is as strong there.
the shader had the same properties as far as i could see - the only thing that was different was the surfaceparm that had metalsteps on one and nomark on the other.
keep up the good work! don't make the steps too narrow
