Nice roach!

ohyeah,
Goto www.highend3D.com and under the Maya shaders area there is one that I found! Haven't looked at it yet cause I have no need at the time but if you want a quick shader go there.
I'm not the master texturer (is that a word?) in Maya yet so I use premade ones when I can't make a good one! But look at the shader in the attribute editor and learn from what others have done! Helps a lot! Hope this helps.
