This. Is. Outstanding. That idea is long overdue, and you is the genius who finally did it!
Your optimizations are also impressive, but i see that you had to sacrifice compatibility with DecalMaker plugin. Any chance to add option for your textures to appear simply on the top of DecalMaker textures? Even if it will cost FPS drop, letting users to choose between performance and DecalMaker compability will be nice addition :)
I will be looking into this in the future because it is pretty distracting, especially in VR that there is essentially just a text dimension inside the body, you do give me an idea for a separate plugin though.
