So I’ve been waiting for this feature for a while and really glad it’s made it in to the new update. I may be being a total dumbass, but how do I actually specify which ICC profile to load into V-ray? I can see the ICC toggle in the VFB but nothing happens when I click on it. ---

The ICC profile itself can be selected when you open the color corrections tool palette (the first button of the lower toolbar), just below the LUT correction. Best regards, Vlado ---

Ah, thanks Vlado. OK so I tested it with a few different printer profiles just to make sure it works and it does. However, when I browse for my moitor ICC profile, V-ray doesn’t recognise it… it doesn’t show up in the folder even though it is an ICC file. Any thoughts? ---

Does the profile name need to be a specific format? At the moment it’s Dell\_3008\_201211\_1.icc. Made with Color Eyes Display Pro. ---

I was really excited to see this feature too! Thanks! I’m hoping it will make things easier for us. Ramsay, I’m using ColorMunki for my monitor profile, to test it out I had to change the extension from .icm to .icc but it was recognized and it’s named in a similar fashion ColorMunki\_20120104.icc So I’m having some issues with the ICC profiles as well, same as dlparisi. Currently work in linear space and have made sure to follow any directions concerning icc profiles on this thread and the one dlparisi posted a link to. However, I don’t see any colour shift at all when applying the profiles. I’m using a wide gamut display so the difference between my monitor profile and srgb is quite apparent and I should be able to see a difference. Like I said, I am working in linear space, my gamma is 2.2 as well as the output. And I’ve tried loading my monitor profile, adobeRGB and srgb, all all images come out looking exactly the same. If anyone has any insight on what I may be doing wrong it would be appreciated. Thanks ---

Can you get me your profile to [vlado@chaosgroup.com](mailto:vlado@chaosgroup.com)? This seems to work fine for the profiles we have tried. Best regards, Vlado ---

That’s it. The problem was windows was showing the file as an ICC Profile. I turned on show file extensions in the folder options and the file was actually an .icm. Changing the file extension worked, I can now load the profile into the VFB… thanks for the heads up! 🙂 ---

I can report the same as aristas. I too have a wide gamut display and so am hoping this could be a solution to the problems of working with max and a wide gamut display. I’ve followed dlparisi link to vlados linear work flow as well as trying many different colour profiles and everthing looks exaclty the same for me??? Generally for correcting colours on a wide gamut display in max i frequently either just use the color correction map to shift the colors back to somewhere close as seen in photoshop or ; the only way to see the exact colors for a map in max as you do in photoshop is to apply your calibrated monitor icc profile to your map (in photoshop using convert to profile), then it will appear correct in max - render scene - open render in photoshop (missing profile should be ticked in color settings) - assign monitor profile and convert to pro photo or whatever you prefer. Not an ideal workflow but it works! ---

What are you guys using to create your profiles? I’m using a Spyder 3 with Coloreyes Pro to calibrate my wide gamut Dell 3008WFP. When I switch between my monitor ICC profile and the sRGB profile using the tab in the VFB, I get a definite shift in colour. Are you sure you guys aren’t just using a profile that is very close to sRGB and therefor not seeing a difference? My profile is very close to AdobeRGB profile, that’s why I’m seeing a shift… the colours look a lot more natural especially with Vray Sky. ---

Great Ramsey, glad I could help! I’m using the program that came with my ColorMunki to make my profiles. My profile is also very close to Adobe RGB, so yes, I should see the shift like you. I’ve tried using my display profile, AdobeRGB and sRGB and which ever one I use, I see no change. macca, thanks for sharing, I had realized the same thing once I finally fully understood ICC profiles, unfortunately I work with a group of people and we all have to work on the same images so saving maps with the monitor profile is unfortunately not an option. ---

Just to make sure - after you’ve loaded your ICC profile using the colour corrections window, how are you trying to activate your profile? Are you clicking on the sRGB button at the bottom of the VFB window? Just in case you didn’t know, if you click and hold down the sRGB button you’ll get a drop down where you can pick ICC instead of RGB. Hope you don’t think I’m being patronising, just trying to make sure nothing has been missed 😄 ---

I don’t think you’ll see a difference using this method. Set your output gamma to 1 then use the ICC tab in the bottom row of the VFB, you should then see a difference. ---

I’m using a huey pro on a Dell 3007wfp. My calibrated profile is also similar to AdobeRGB. I get no color shift whatsoever when changing any of the color profiles using the tab on the VFB. ---

Yes, perhaps it is not very clear that the sRGB button is now a flyout button; if you click and hold it, it will expand to allow you to choose between sRGB and ICC color correction. Best regards, Vlado ---
