Hello,

 

I'm trying to display a texture over my terrain (which is pretty large), and I don't know what I could do to have the best effect possible.

 

I want to see the textures in a good quality when I'm close to it, but if I duplicate them the same size all over my terrain, it's pretty ugly and "noisy":

 

Far distance:

Close distance:

Shader:

So, what could I do so it doesn't look that bad on far distance?

 

Thank you!

One approach is to sample the same texture twice but at different scales, but it looks a bit cheesy nowadays.

 

Another is to simply have lots of different textures to hide the effect.

 

Yet another way is to use wang tiles - http://graphics.cs.kuleuven.be/publications/LD06AWTCECC/LD06AWTCECC.pdf
