@Hornet3d Are you rendering in Firefly or Superfly? Making the luminous parts cast light might give the gentle fill light you want. I have a partial material, an MT5 which is only a group of nodes, which you can add to (not replace) those materials. Works great in Superfly. In Firefly, I have to make extra parts, unseen clones of the parts which need to glow.
For example, if those amber illuminated bits use a texture JPG plugged into the root node's ambient socket, you would add this group of nodes, and plug the texture map into both of the places shown in the new nodes (pink wires). Then plug the lightcasting output into the root's ambient, in place of the direct texture map connection. Adjust the "
light boost adjust" color block to adjust the strength of lightcasting (darker gives stronger response). Zip of partial MT5 attached.
