Iray glow question

I am wanting to use Foreverstones in my render but I can't get the color in the stones to glow like the promo because it is an older prop. I am wondering how I can get it to work for Iray?

Apply the Emissive shader to that material zone,
I tried that, but it lit up the whole prop because stone and prop are the same. I don't know if the image is achieved via 3delight render or by postwork
There is an Ambient Strength map called stn01_amb that you can plug into the emission color channel. That will make the viens light up without lighting up the rest of the stone. Here I applied the Daz Studio materials from the pose folder, and then applied the Iray base shader. Then I put the required map in the image slot and grabbed the orange in the color slot.
Here is sample render and my settings. Luminance is set 100000. This should get you going the right direction.
Awesome!!! Going to give it a shot. I did a render earlier today that took close to 5 hours to render and while I was ok with the drab non-glow, once I took it into PS to try and produce something like it... I was admiting defeat :)
Edit: It worked! Thanks for the tip!!
Great! Good luck!
Two related ways...the first requires making an 'emission specific' texture map. You take the image into an image editor (Photoshop, GIMP, etc) and fill in everything you don't want to cast light with pure black. This would preserve things like the 'lava' texture.
The second, create a mask. For the mask, everything that is white will glow...so make what you want to glow white and everything else black.
You then place either into the emission channel. Set the emission color to white for the first one and to whatever color you want the light to be for the second one. Also make sure the color temperature is set to 6500.
This is using a mask in the emission channel (second method)...
And this one uses a texture (first method)
Looks good
The techniques work in 3Delight, also. Use the UberAreaLight and then you just need to plug the mask into both the Light Color AND the Ambient channels. Use the same color for both.
