I would like to use vertex color information for texturing. I found some description on the web but there is something what I can't figure out. If I use a color at 0.5 value, the FAC value through separate RGB node looks like not 0.5 result. What am I missing?enter image description here

  • $\begingroup$ If I disconnect node from FAC at mix shader and set the value manually to 0,5 I get the result I'm looking for. $\endgroup$ – hiuuz Aug 31 '18 at 5:03
  • $\begingroup$ I put a 'Gamma' node between the 'Attribute', and 'Separate RGB' with a Gamma setting of (1/2.2), that is to say, (0.45454....) and it seemed to correct the 'Fac' in the mix. A proper answer would explain which color spaces get used down this pipeline, and justify the setting, so this is just a comment. $\endgroup$ – Robin Betts Aug 31 '18 at 8:20

  • $\begingroup$ The gamma node really helps, Thank you! The background of color spaces is "chinese" for me at first look, but maybe later I will learn about this. $\endgroup$ – hiuuz Sep 2 '18 at 17:43
  • $\begingroup$ It is confusing, because which spaces are used by which bits of the system is not always well documented. $\endgroup$ – Robin Betts Sep 2 '18 at 18:19
