How to fix error CS0246?

Question

Unity

Hello! I downloaded post processing from the package manager and now errors CS0246 have appeared, what should I do?
Deleting post processing didn't help.

Answer 1

apparently you can't find TextureGenerationSettings somewhere

The type or namespace name 'type/namespace' could not be found (are you missing a using directive or an assembly reference?)

Answer 2

After downloading, did you update the textures using Post Processing itself? After connecting the package, you need to update the materials, etc., this is done automatically in the Edit tab, if I'm not mistaken. Or better yet, study the introduction to Post Processing in more detail.
