Why I have those multicolored glores in my scene?

lol, ok first, you havent givin us any info enough to help you. Heres a hint:

  • What version of Unity are you using?.
  • BuiltIn, URP, HDRP?.

What i can see is: the rainbow effect ONLY effects objects (plane, boxes, cubes). Most likely a material/texture import setting, shader issue, etc.

I use unity 2017.4.4
It effects on objects without any textures or materials

BuiltIn, URP, HDRP? I don’t know what is this

Hi, have you tried installing a newer version of Unity (like 2022.3) and see if it still happens?

You even cannot submit a bug report because the support for 2017.4 was ended in 2020.

I would also suggest a newer version (latest 2021 IMO, but any, really).
