IMPORTANT! The newest file is the 0.3h Hotfix which is a improved version and fix of the "Hoth" retexture. It fixes the missing-textures-issue, which some users have reported. This is an addition to Full Version 0.3 and 0.3.1b, so if you didn't already, download all three packs together.
It looks blocky, or hoth isn't a good example.
What exactly do you mean? DO you mean the level looks blocky? Well that's got nothing to do with the textures, I don't edit the meshes, only the textures. Just compare the two pictures in highest resolution and you will see this one has much nicer textures which look more realistic.
