IRay Emissive question

CrystalwizardCrystalwizard Posts: 102
in Technical Help (nuts n bolts)

I have an existing object from an older product that has flames as part of it. I would like to add the IRay  Emissive function to the flames. I do not want to just load a ghost light and put it where the flames are, I want the flams to glow and be the light source.

However I can't find anything that explains how to do that. Can anyone explain, please.

    load the item into the scene. Select it, open the surfaces tab, select the surface you want to emit light. Find the iRay Uber shader preset at My Daz 3D Library ->Shader Presets ->Daz Uber->!Iray Uber Base and apply it (by opening it while the correct surface is selected)

    Now on the right you should have a bunch of property sliders for the surface. Find Emission Color. Click the color bar (should be black with 0.00 repeated 3 times) pick a color you want the flame to be.

    Now a bunch of new properties are available under that. Emission temperate will determine the color of the emitted light. Lower numbers are more red. start with 1000 and adjust from there.

    Below that you'll see Luminance, and a luminance units picker. The higher the luminance the bright the light will be. Since Iray models light "accurately" light intensity falls off dramatically with distance so do not be afraid to bump the luminance value seemingly quite high toget a satisfactort result.

    Click on the fire, go to surfaces tab, scroll down to the emission section, plug the fire texture in there, or you could just turn the emission to a solid color, depending on how "hot" the fire looks. Or you could also turn emission to white, and control the color with the temperature slider that should pop up as well

    I would, but there ISNT an emmission section.

    That sounds very promising. I'll try this, thank you.
