Title: LUT Correction
Post by: aref3dsmax on 2020-06-25, 09:32:14

Hi. I have a question about LUT
when I turn on LUT my scene render will be good but my sky going to wrong color
and then turn off the LUT my scene look bad! but my sky is very good.
so how can I separate it?

is that way to exclude an object or material from LUT ?

You can use Corona Tonema Control for that, you will be able to disable exposure, tone mapping and lut's for the background sky or hdri.

Just a note: Tonemap Control will not be always able to negate the effect of LUTs. Sometimes this is not a matter of simple "inversion" and then it fails.
