little problem: 3 large textures (4096px x4096px) should be presented as sharp as possible on an HD screen. I tried a basic shader but it looks very soft. also when i take 3 filetextures it looks a little bit soft…
try playing with texture filtering. change from linear to anisotropic or point for example. or try to play with mipmaps. 1mm is the sharpest (as i can remember, i’ve never gone deeper in mipmaps) or read the limitations of your videocard (maximum texture resolution (my older one has a maximum of 4096^2 texture resolution)) feeding it something higher than that could cause some artifacts.
but yeah the definition of “soft” and “a little bit soft” would come handy ;P
