with a checker texture but it didn't illuminate the environment.Originally posted by THX1138
It's a texture map you can paint and apply to your model so that certain parts will glow. It's applied to the incandescence slot of your materials attributes. It works best when used with final gather. Here is an old test render I did years ago using such a map.
Yeah there was, there were tutorials everywhere on GI but only fuzzy parts on how everything worked!Originally posted by GecT
Neo, I actually did a few more tests but that would've made this image too wide and I figured I'd skim it down, three was enough I guess. Is it just me, or a few years back, wasn't there like a boom in GI tuts all over the net, but they weren't explaining anything about MR? Just click here and click there.

Benny you only need to turn on FG in Mental Ray to get the shader to illuminate, no need for a photon emitting light (just make sure you uncheck the use default lighting option in the general tab of the render settings) As THX said boosting the incandescence will help, you have to watch it with that though or it'll create hot spots and still may not illuminate as much as you want, and that's when you'll need to pull it back some and boost the FG scale in the render settings (those numbers depend on the scene scale, so its a lil trial and error).
