BOM layers that can glow.
Would be quite nice and remove onion layering for mesh models and help save on resources.
I know PBR is a thing but it does not allow the flexibility of BOMs. I have species that have different glowing markings and bioluminescence on their bodies that I'd love to be able to do in SL.
My team and I heavily utilize BOMs so our customers can make rather unique pattern and color combinations.
Shiny BOM layers would also be really nice.
