Today I created a little room in WED. Just a few blocks without any shaders. I reduced the image size even to 512 for the walls and 256 for the rest and it still looks good in-game and runs very fast.

I used only a few of our 88 sci-fi textures:










A shader level in Sphere will follow soon.

PS: I am still uploading the big texture pack and will tell you when it is finished.
