As an applier creator for body materials and tattoos for mesh bodies using the SLUV - it is tiring and quite redundant to program applier scripts for each body (and heads) that I would like to support. It would be an infinately more efficient system overall for all bodies if they could simply utilize a specified UUID channel that grabs those textures from a BOM wearable to get directly applied as materials on the rigged mesh wearable. Something like additional AUX layers that had multiple channels for normal and specular (or even PBR materials) for head/body UV in them. Almost all mesh body wearers have updated to BOM skin for bodies and heads, and often struggle with adding and removing materials in HUD based systems. Implimenting a system like this would make changing materials on bodies easier for base line consumers who are about to experience materials for the first time when all viewers have updated to PBR. Along with this request, I need to stress the importance of 2K bakedown service for these materials to be worth making a BOM asset. The payoff being - bodies would not need to add another stack of scripts to compensate for PBR materials on their mesh bodies and heads, which consumers are already wanting. Addressing 2K BOM requests with the ability for materials to also be BOM would greatly combat an increase in constantly running scripts in bodies and heads, and would make the entire community much happier for it!
