im having a trouble rendering a gold material, i always get this step-like gradient in the darkest parts of render.
the problem is that when i try to render in a small resolution (like 2000x1000) with like 5000-7000 samples - i dont get those steps..
but when i set resolution to 10000x5000 - i always get this problem.

i tried making my hdri like 5 times bigger, bit more blurred and even with some noise added, just in case.. but the result is the same.
i dont use post-effects (bloom or glare).
im my gold material i got rid of most channels, that could have done this.. have only diffuse/specular/roughness left, w/o and channels/textures inside.
and i still get these stripes in gradient.
tried rendering 8bit and 16bit in tiff or png.. no use

please help

ok, can you try with floatbuffer and 32bit tif output?

where can i find a floatbuffer?

render settings->buffer type = float(tonemapped)

kk, trying that, thanks..
will take bout 30 mins of render to see if the steps r gone..

YES!!:D

Thanks a lot, aoktar!

it works!! :)
