Studio parts editor, decals, connectivity...

[Philippe Hurbain]

I’m curious why they chose to “roll their own” solution instead of using the already existing texmap support for LDraw.

I'd like to know too...

I like Studio but I’m having a hard time recommending it because they’re not giving back to the LDraw project.

Not completely true now since Studio part admin is a new but active LDraw part author!
