Here we are !
Given how extensively this gimmick has been used, I can start to release it at 1.0.
You know what they say, if at first you don't succeed, name it 1.0.
Still, this works fine for a lot of cases :
demo-vrchat-blender.webm
demo-vrchat-vrm-tex-converter.webm
The UI still need to be vastly improved.
But the core project is now mature enough to be released on different websites (Booth, Gumroad, Vket Store, ...)
