So yeah, in case anyone hasn't heard yet, the BoM Firestorm came out a couple days ago. I've been using it and I honestly can't tell if I've run into anyone using BoM yet - which I suppose is kind of the point, being a QOL feature for people building their avatars and not necessarily for the ones viewing.
A well crafted avatar works on all Viewers. Mine doesn't use BOM so it would have looked fine on Firestorm regardless.
Besides, if you derendered me i wouldn't even know and if you blocked me i wouldn't know either, jellydolling me wouldn't help since i wouldn't know that you jellydolled me... so this whole thing is kinda pointless?
It's one tool more to aid us in optimizing content and reducing both mesh complexity and memory usage. Badly used, it saves 1-2 layers of your body that would otherwise double or triple your polycount and texture memory usage. Properly used it can save all layers and can be used to quickly and on-the-fly alter a texture. The possibilities are quite huge, people just don't realize what BOM entails and what it opens up. An extreme example: I could use it to split a body texture into several layers, taking a dragon as example, i could use a base color, multiple gradients, tattoos, markings, details, extra body details (such as bits and nips) and even a multitude of different scales variations (amount, density, color, size, area covered) and they all can be mixed and matched and combined infinitely, not to mention that with them being handled as clothing we could easily do extra things like recoloring them.
BOM is much more than just oldschool baking on mesh.
