Pale trees and shrubs

Hi community I have 3 small problems

  1. My whole bushes and trees do not have saturated color.

  2. Not all textures that are where they should be after the upload on Steam.

  3. I have everywhere I look this circle in sight.

Here’s an in-game picture with my 3 problems.
At the place where sand can be seen in the editor is a grass texture


Thank you for your help
