Texture blurry on distance

Hi there

I’m pretty new to blender and I’m working on a 3D Tetris. I just started and I’m trying to get the level design done. I created some textures but the get blurry on distance in Unity. When I move the camera by them, they look good.

Can someone tell me how I can fix that?

Thanks

The texture size is 1024x1024 ( I tried it before with 256x256 with out any change)

that’s because of the mipmaps,

you can either turn them off, which will cause the lines to become pixelated in the distant,

or you can use anisotrophic filtering, which will give a nicer effect (smoother lines), but is more expensive.

You can change these settings in the texture’s import settings
