Dear Corona Team,
We've encountered a strange issue which might be related to CPU manufacturers. In our office, we have dozens of Intel Xeon and i7 machines, as well as AMD Ryzen machines.
We are working on an animation, which involves river water rendering. The river water geometry is a simple plane, with a simple material, with bump, diffuse, etc, so no simulation included.
We experience that our ryzen and intel machines render the water differently, but the difference only occurs in the far distant areas, close to the horizon. I've attached the same frame rendered by a ryzen and an intel xeon machine. (We have the exact the same version of corona, max, plugins, scripts installed on all machines.)
We tried to investigate the issue by turning off diffuse, reflection, refraction, bump, etc, and what we experience is that this problem is most likely related to bump. If we turn off bump, the renders are the same. We turn bump on, it's different. Changing the bump texture in any way does not help.
Do you happen to know the reason or the solution for this issue?
Thank you,
