How to Plug-In Bump2d to Mia_Material

Image from http://forums.cgsociety.org/showthread.php?f=87&t=422814&page=6&pp=15

This really took me awhile to get it~

Because u can see there is no direct way to do Bump with Mia_Material

Here is the trick:

1. plug a misss_set_normal node into the bump slot ( Connect miss_set_normal.message with mia_material.bump)

2. plug in the usual maya bump2d/3d(and link ur bump map like usual) nodes into the normal vector slot of the miss_set_normal node

hope it helps to ease ur pain too :D
