Noise on textures

I don’t know but if I look textures with a certain distance and angulation, sometimes I see this:

You can see a “noise” on the texture, and sometimes this noise can be harder.
What causes it?

Your code doesn't make much sense as rotation.x is not an angle! You're dealing with a Quaternion here. You probably ment to use transform.eulerAngles.x. However the euler angles representation of a rotation is not very reliable.

Try increasing the aniso level in the texture import settings: Unity - Manual: Texture Import Settings

Unfortunately it doesn't change anything :(

Another photo with this “Noise”, maybe is shadow caused this?

What you’re seeing is a Moiré Pattern. In general for game engines, it’s caused when a texture with some sort of pattern to it mixes with another pattern. For example, a checkerboard pattern can display this problem very noticeably simply by being viewed from a steep angle. The limited number of pixels available to display the pattern on-screen results in the texture skewing in this manner.

An additional potential cause, however, comes from shadows. Potential solutions to this can be found here. In general, tweaking shadow settings on lights can potentially solve, or at least mitigate the problem.

changing Aniso Level in ALL textures doesn't solve the problem... anyway i think that the problem is the directional light, becuase if I disable it, there is not problems i tried to change settings of the directional light, but the problem will solve only if the light is off

OK, i solved a problem using the correct value of Bias on the directional light... but i discovered that problem in the first image is different, where adjusting shadows and aniso level doesn't work
