Doing what? The thing @8Keep123 talks about is already done, as I’m pretty sure he’s referring to: Support for geometry and tesselation shaders (diff) - #84 by Empire_Phoenix.
You called these sort of things ‘hacked together stuff’ in an earlier post and that people are basically too lazy to implement it in the engine leaving it to do for the core developers. But if someone like him actually wants to help but doesn’t exactly know what needs to be done (the how in this case), then an answer like ‘The problem is not how its done, its doing it’ won’t help anything.
