In The XCC Mixer, on all the maps and buildings, the pics are blurry, is there a way to make then clear?

can you show me a screenshot?

Are they different parts of the map in one file, or one thing that is just blurry, cuz it may be the different parts, im sure all have it...so maybe its regular and im just not seeing something...but here is SS:

oh yes, that dds have something todo with the lightmap´s
its normal, and better is dont try to modify them!

Ok ty
