I rendered these as a test to see whether the engine of BF2 can handle lightmaps at this resolution or not. Luckily it seems that there isn't a major performance impact so far, but at this moment I can't also say that this will cause a smooth Bf2 either. Once I have rendered all the objects as well as the terrain, then I can see if this can feature in a mod. Take note that these screenshots only show the HD lightmaps on the static objects, and not on the terrain, so don't ask me why the terrain is so low definition while the buildings are so HD. :)
