Problem with distance

Hi everyone, i don't think this is a shaderlab problem, but i don'y know where to ask it...and maybe it really is a shader problem, i don't know^^

Look at the image i uploaded:
As you can see, there is a precise point in depth, where the rendering of this long cube starts behave in a strange way...this is horrible to see, and i'm sure there is a way to solve this...any idea?

 

You can most likely solve this issue with anisotropic filtering and/or trilinear filtering. You can find these settings for each texture in the texture import settings.

 

Thanks, exactly what i was lookin for!
