Soap assets

Hello everyone, good people, I ask you for help. I was doing a project, decided to increase fps and went into the rendering settings, disabled a couple of functions lumen and ray tracing according to the guide on YouTube, and then after that I had a problem that all the assets about the zoom became so terribly soapy, disgusting. I will say right away, I did not get into the texture and material settings anywhere, I am a newbie in the engine. I tried to delete the entire project and the folder with all the assets from megascan and deleted the engine and downloaded a new version, all useless, the problem does not go away. If you know how to solve the problem, then tell me in detail. And also I have VT turned off.
