![]() I’ll need to investigate that more.īased on your explanation, I did some quick tests with mixed results. ![]() The conversion process sometimes results in values above 1 which can cause incorrect calculations in PBR shaders which is why I was asking about working w/ Color Management turned off. I was creating some transmissive shaders in Arnold recently and ran into some unexpected results that seemed to break the material when working with output-sRGB values. If I input RGB values with ‘Color Management’ enabled, ACES will convert these values to ACEScg using an inverse of the ODT (which includes the RRT) that’s been specified in the color management settings. When Color Management is disabled, they are scene-linear values within ACEScg colorspace. Just to make sure I truly understand, with the OCIO config setup and ‘Color Management’ enabled in the color picker, the RGB values I’m seeing are display-referred sRGB values. Thank you for the explanation! I take comfort in knowing I’m not the only one who feels like my brain has been put in a blender when trying to wrap my head around this color picker stuff. The swatch below was created in Photoshop with the following RGB values: 95, 148, 208. How do I correctly input RGB values to match color swatches or other materials that require specific RGB values (like metals). When Color Management is enabled, is this applying the RRT + ODT to the sRGB values which ends up tone mapping pure white values from 1.0 to 0.811? Does this mean I should be inputting my sRGB values w/ Color Management disabled to avoid getting values above 1? In Chris’s article about color picking, he states these values are display referred, which leads me to my next question. I’ve been struggling with inputting sRGB values into Maya’s color picker. I’m using VRay and the OCIO ACES 1.2 configuration. I’ve decided to convert to an ACES workflow this year and like most people here, I have questions! I’ve been reading forums, how-to articles, Chris Brejon’s awesome explanation on ACES, and just when I thought I understood what I was doing, my confidence has been shattered yet again. ![]() This is my first post, so I hope all the images upload correctly.
