I haven't, the other community I was thinking of is !artshare which has 3.94K subs.
My style is low-poly with vertex colors (no textures). My Blender questions weren't really that important, the roadblock I am having is trying to use said models in a specific framework (or maybe the very specific bindings I'm using) just not loading vertex colors (I am not sure if there is 'help' here, aside from just fix it).
