And part of it could be that no one as developed a "nice" looking texture for that material type. I also see that one material can have several texures assigned . > Are they selected randomly at startup ? > This I believe was added so that you could do some randomization and reduce the problem with repeating artifacts in the land cover ... the downside is that this randomization doesn't blend well at the borders like you can do with a single tiling texture ... but there are always trade offs to everything I guess.
