Hello GA members,

I made sure I checked the search function before posting this so I think im good, then again I could fail super hard at the interwebs and it could have been the first search result and I was just too dumb to realize it.

Anyway I have a model that I wish to glow using an emissive. Did the whole jazz of creating the emissive and got it to make it look kinda like a light bulb in max but not glow. Didnt care to much about that since I knew you could do it in UT3.

On my model I wanted a kinda back computerish screen to glow blue, and white text and a palm print to glow white. There were some other side lights to glow blue and other text to glow white also.

Problem is that when I hook up my emissive map in UT3 its making my model glow the color of the emissive map instead of making the textures from the difuse glow. I assumed that the emissive map would just make the colored textures on my difuse glow depending on the intensity of white/grey on the emissive.

To check if this was acutely the case I hooked up a Constant3Vector with a blue color and a multiply and used this with my emissive. Sure enough everything glowed blue and totally ignored the colors of my difuse.

So my question is, is this this even possible to get these multiple colors to glow? Or can an emissive only do one color? Checked for tuts online but every example i could find used 1 color in there emissive so it didnt really help. If anyone knows I would extremely appreciate some insight on this.

Here is a quick render of what my object looks like in Max (its not really glowing, its just kinda lit, couldn't figure out how to make it appear glowing) And of what it looks like in UT3 with the emissive hooked up.

Thanks again for any help.
