I tried again to get the correct result. I updated all drivers and installed the latest Blender 2.93.6, 3.0.0 Beta and 3.1.0 Alpha releases. I can't understand what the reason is, but again on Beta and Alpha - when rendering Cycles, the result is incorrect. According to your advice, I turned off all the reflection nodes and others, left the texture leash - the result unchanged (((I also tried to render with the processor and on the video card - the result is the same (((And on version 2.93.6 - in all scenarios it turns out the same correct result .... Tell me, what could be the matter ???? I attach screenshots
