Acutely the only thing thats helping with the Fake Bumping is the armor and alittle bit of the rubber. It makes it look more sharpand intense (depends on how you set the levels at). In the normal the R and G channels help the rubber mostly while the B channel helps the armor more.

Never the less its still good to have a tut our there to do it the "right way" as dee calls it but meh.


Well all i did was gray scale the normal, then added the blue channel back on as a multiply like dee does it. Adding the RG channels when you have the blue channel on already on the diffuse really only helps the rubber parts mostly.
Here is the diffuse with all the channels attached to it



And pope ill do that. brb
