Introduction to Maya - Modeling Fundamentals Vol 1
This course will look at the fundamentals of modeling in Maya with an emphasis on creating good topology. We'll look at what makes a good model in Maya and why objects are modeled in the way they are.

But for a glow map, you need to apply it to the incandescence slot in your materials attributes and control it from mentalray. Object illumination is really fun to work with.

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.
does someone know how to fix this?
EDIT: I used mental ray with final gather and photons
Thanks in advance,
Benny

I did a quick example of what the effect looks like. I also applied the special effects glow option to get the flaring gradient effect. I still think that effect sucks when done in maya.

when i was learning lighting and shadows (hell i STILL don't use MR, let alone haven't really learned how to use it) for raytracing and soft shadows and the like, there were only a few tutorials that helped, because instead of saying 'do this, now do this, now do this' (which just gave you their result instead of how to achieve your own) they would have images like yours that would show incrementations of settings to show you how it alters the render and to what extent.

Benny, grats, lol now all you have to do is tweak that and add the glow in post. Personally I rather map the ambient, boost the incandescence just a wee bit, and crank up the FG scale settings rather than hiking up the incandescence too much.

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.

those are the ones that actually help someone learn the ins and outs of the program... the others just show you how to do what they did.

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).
