Yea, maybe CMP or someone has gotten permission. But make sure not to release it without getting permission to use the stuff. We have to respect other people’s work, no matter how old it is.
Honestly, if the map is good, someone could come along a make some statics for it one day, you never know. Just concentrate on gameplay, I believe people liked the first test, so with tweaks hopefully it can be better on the 2nd test.
I think that once gameplay is where you want it, you can comb through an polish it to fix things like player movement and FPS drops and memory issues. Then things like textures, statics and lightmaps could be worked on to make it feel finished.
