    Good day everyone!
    Colleagues, tell me, please, what are these circles and how to remove them? Nothing helps. Thanx!

    it's mipmapping. beyond the distance of these curves you're seeing, the texel/pixel ratio gets too high so a lower mipmap level is accessed. Since you set your filtering to bilinear rather than trilinear, you're getting hard edges rather than blending between different mipmap levels.

    Thank you so much! Helped a lot)) What do you think, is it better to apply trilinear only on terrain or to all textures in the project?
