Add emissive without changing the material

I want a material on a object to shine. It is metallic and has a very specific material that I can't replicate when I apply the emmisive shader that comes with daz3d. Also when I apply the emmisive shader the materials change so it looks totaly diffrent.
How can I make it so it gives some light?

    Is this with Iray or 3Delight?

    Iray

    Put the surface colour image for the material in the colour slot in the Emmisive tab, set it at 6500 and lower the Lumens until you get the light and the material balanced so that the material shows through the light.

    As @Fishtales says. Emssive properties are an integral part of the Iray base shader, so just makign the surafce emmisive my adjusting the relvent settings will not alter the other meterial/shader defintions.  What might change things is if you add an emmisive preset.  Also don't forget to change the emmsive base colour away from black!

    I don't understand. What is the surface colour image of the material and where do I find it?
    Do you mean the base colour? I think my material is more than the base colour which would make it look not like my material then.

    My material is this

    Is there a colour image in the Base Colour slot for the material?

  • IllidanstormIllidanstorm Posts: 655

    No, just a colour.

    There is a map in the Top Coat Colour, I would try that one.

    Ok I tried it, now it looks like this?
    I applied the material, then put on the emissive shader and then changed the base color image. It does not look like metal at all anymore. What am I doing wrong?

    If a surface is emissive that overrides other properties, you can't have a material that looks normal but emits light. One way to handle this might be a ghost shell - create a Geometry Shell, apply the emissive preset, and lower the Cutout Opacity to a low but non-zero value.

    Good idea. It worked. Thank you. Now it can give a red light.

    Drop the Luminance down to 10 it looks too bright at the minute and change the Temperature to 4500 or 6500 and see if that helps.
