Like the title says

I noticed with some of the LEGO materials I've been experimenting with, there are some that have some degree of emission under UV lighting and such. I know we can't do that with LuxCore, but in direct light they do have emission as well, like so: Is there something special I need to do or is it simply a matter of adding an Emission component? I don't want to turn it into a full-on light source, it's more of a volumetric effect from what I am gathering. Maybe I'm wrong?

You can add emission to the surface or to the volume, in both cases, it will cost nearly nothing because it will not affect direct light process (assuming the item has several hundred of triangles).

Neat, thanks Dade

I'll try it on the volume, see how it looks

EDIT: Alright, I think just doing emission on the surface is best. Volume-based emission for this is extremely overpowering.
