Weird Moire Effect

[Blmrs]

Hi All,

Have this issue with my renders and I can't seem to isolate what's causing it. It look like moire but I'm not sure. Maybe someone has an idea what's happening and why?



I've tried higher res textures (1K to 4K), tried using HDR instead of V-Ray Rec Lights. Played with subdivision levels on lights, materials, reflections and render settings. Messed with AA. Nothing.

No clue where to go next. Any help is appreciated.

Cheers.

Do you have some displacement or bump map? Is it an 8-bit map?

Best regards,

as vlado says, that definitely looks like an 8 bit map in there. you need to re-create the map in either 16 or 32 bit to remove the banding.

Displacement, yes. I'll check but I think they are 8 bit. Sigh...
