Is there a way to make fur glow? *Solved*

I made a custom texture for oso fox, and I would like for part of it to glow.  I made an emission texture, but I don't see anywhere to plug it into the fur surface.  Does anyone know if there's a way to do it?

    Ooh, glowing fur, my nemesis.

    I can't tell if by "custom texture" you mean you're just basically recoloring the fur that came with the fox, or whether you're using a different shader, or what. If you're using the dual-lobe hair shader that Oso used for that fur, then you CAN force it into plain Iray mode (using the "Iray Uber Base" tool). Then you'll have an emission setting.

    BUT I warn you now

    1. You may get strange results (for one thing, you may find that a color/surface image you put in the Emission Color slot gets ignored)

    2. Your renderer is going to hate you. You are making an emitter for every strand of hair. I have a fairly overpowered machine and when I tried a test, it sat in "Retrieving lights" for close to five minutes trying to wrap its head around all those emitters.

    An alternate approach, and one which your renderer will hate far less, is to make the SKIN glowy, not the fur. The glow will shine through the fur, and, depending on how high you turn its luminosity, gives effects ranging from subtle to "spectral blob." This one's set on subtle. I have made ONLY the "coat" surface of the body emissive, and given it the same emission color map as the base color itself.

    I have the hardest time using the right words for stuff XD  What I did was take the white fox texture into a drawing program and draw over it on new layers, basically.  Then I merged one with the (copy of the) original for the skin, and put one over a black background for the emission.  The emission works perfectly on the skin, but I want the emission to glow on the fur as well.  

    I'm a little worried about making every strand emissive, that sounds dangerous lol!  But I guess I'll give it a try, maybe if I render the fox on its own, and then stitch it together with the background in my drawing program, it might work?  I'll give it a try.

    Thank you very much, columbine!

    That's what I ended up doing.  I split my emission map up and the parts of the hair that were longer and thicker, I made a geoshell for.  The couple of pieces I needed brighter I just cranked the luminance way up.  I think that's going to work.  Thank you so so much!!!

    You've got lots of clever ideas in your gallery, I hope to see what you come up with.

    Thank you so much!!!  When I get it finished and posted in the gallery (probably in a week or so), I'll post the finished result to this thread as well.
