I've had this idea in my head for quite some time, using DECALDEF to create cool animations on the walls. You could create groovy disco lights, team-icons for CTF bases, projectors etc. using animated decals. I've never seen it done before though so I thought I would submit this to FX as an example (which is useful in its own right for maps)

Submitted: inkoalawetrust Code: inkoalawetrust (Improved code), DrPyspy (Original base code) Sprite Edit: Custom sky camera graphic by Tabijaky, made from GZDB/UDB's sky viewpoint graphic. Idea Base: Source Engines' 3D skyboxes.
An improved variant of ZDoom's existing static sky viewpoint actor, unlike the ZDoom sky camera, this camera will move relative to the players' camera, making it so you can move closer or further from objects like distant hills that exist within a skybox sector, instead of the camera staying in place, similar to 3D skyboxes in the Source Engine.
