I've been messing around with the LambdaGeneration API, though I don't actually know how (or if) you can get comments for a post using it. So perhaps there should be some API docs, or just telling me what API route to use to get comments would be good enough.
If there's any features you want in StudioMDL, please tell me! Since I have a custom version of it, which is basically at Sven Co-op levels in terms of vanilla GoldSrc. I can add pretty much anything. So for example, I may begin working on adding support for pretty much every 3D model format out there, so you can export to OBJ and be able to reference it in your QC and it'll just work.
I've been working on a custom version of StudioMDL, it's not quite ready for release yet. From a vanilla GoldSrc perspective, it's at the level of the Sven Co-op version of StudioMDL. It also runs natively on Linux (thanks to fnky's cross-platform version). And since it's my own little project, I can add any features I want! So, you'll basically be getting the Sven Co-op compiler but with more features. I've mainly been fixing bugs so far, but there are some new QC commands (mainly flipping UVs horizontally and vertically).
"The skybox at the end of the tunnel" I don't really know if I should put it in Source, or in Half-Life, since it isn't Half-Life related, but is fan art (I made it in Blender).
