Can you have "glow maps", like a bump map?

When in doubt, delete history and freeze transformations.

I assume its like a transparency or bump map

Oo, OK, sorry for the stupid question... I had something else in mind when thinking about the glow attribute...
I gust tried it in Maya BTW, and it doesn't seem to work right
Maybe it's just me...
edit: it does when using alpha gain as value

what's a glow map?

---

that's a "Ch" pronounced as a "K"

Computer skills I should have:
Objective C, C#, Java, MEL. Python, C++, XML, JavaScript, XSLT, HTML, SQL, CSS, FXScript, Clips, SOAR, ActionScript, OpenGL, DirectX
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D

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.

You assign it to the incandescence slot? not the glow slot?

i assumed it was putting something into the incandescence slot because i never heard of "glow slot"

thanks for explaining THX1138

There is a glow slider on Maya materials, under special effects I think, though you can map stuff to it I don't know how much control you'll get with that since there is a node that influences all the glows in the scene anyways (that default shader glow that you see in hypershade). Its worth a try.

Ok, but whats the glow one for then?

There is nothing labeled glow slot. It's labeled special effects and the effect just gives you a flaring gradient effect. Like the flaring gradient from a light sabre. The biggest problem with it it is that the flaring effect gets worse ( it gets huge ) the further you move your object away from the camera.
