Welcome to GrangerHub Previous69 ,
You may or may not be aware, but GrangerHub is currently working on the next version of Tremulous, with a new client and new servers (There will be a post soon elaborating further on this project). One of the features of the new client (besides being multiprotocol and capable of being played on all 1.1 servers, gpp servers, and the new servers) is a new OpenGL2 renderer. The new renderer looks awesome (while still having good performance on lower end computers) even on old servers with the old assets as you could see in the screenshots of this post:
But to take the renderer to its full potential, new assets designed to take full advantage of the new features are required. If making such new assets to be tried on the development server is something you might be interested in, I recommend that you take a look at this topic:
I would like to add that having multiple skin sets that players could choose from and switch between in the new servers is definitely a feature we would want to include in the new version, when the appropriate assets are available.
