  1. Hi James, yes, I was talking about the OCIO adjustment layer. Thanks again for the explanation, very interesting and very useful especially with the naming convention!
  2. Hi James, thank you for looking into this and the detailed write-up. The workaround works fine. It also worked by assigning the mask to each layer but that's not very efficient. So thanks for the workaround! I'm fairly new to Affinity and all the OCIO and ACES workflow. I'm working in Cinema 4D with Octane and I usually produce more animations than stills, which worked pretty good so far with linear. Stills however are different because of the ICC system. Regarding the object layer color: it can be expensive to render out straight alphas for animations but I also got to say that I don't use the object color layer workaround “correct” here, but so far it always worked in PS. If you're interested in this workaround, there is a talk from Drew Nelson who explains this workflow [at 10:10]: For stills however it's absolutely manageable to render out clean alphas and I will just do this now or probably switch to cryptomatte in general. With the exr stills I want to completely finish my frame in Affinity so the output will be 8/16 bit. I usually work with the ICC display transform turned on. I quickly rebuild the image in an extra Affinity file as I didn't save the history before, so I probably just didn't pay attention to this. But thanks for the explanation and the procedural texture solution! My workflow with this rendering was using the OCIO with source color: ACES — ACEScg, output — sRGB and the LUT is used to convert the image from linear to ICC srgb, so I can assign the sRGB IEC61966-2.1 (Linear) ICC Profile and get a correct export. But as I'm said, I'm new to this so its totally possible that I'm also making a mistake here. So far, the final export looked like it should. 🤔 Thanks for all the help!
  3. Hi Chris, thank you and thanks for the reply! I uploaded the EXR, affinity file and the LUT into the dropbox. I had this problem on all my EXRs so far, unfortunately I can`t share the others because of NDA but let me know if you need another example.
  4. Hey everyone, thanks to the great OCIO support and the performance, I´m using affinty photo more and more to process my still linear exr renderings out of octane for cinema 4D. Unfortunately I'm having an issue with alpha masking of groups with this workflow. These are the steps I take: 1. I'm rendering a half float linear exr and use the "object layer color" for alpha masking [because it's faster to render inside of octane]. 2. I take the exr into affinty [1.8.0.585] 3. Use OCIO to convert the Image to sRGB 4. Below that, I adjust my exposure if necessary 5. On Top, I have a LUT to convert the Image to sRGB ICC 5. I right-click my black and white (but still RGB) object layer color and rasterize to mask 6. I drag a drop the mask on my grouped beauty [regular beauty and denoised beauty] 7. As a result, the mask is very pixelated and unusable. Masking a group seems to cause the problems. Without the group everything works with and without OCIO. The same mask and grouping works fine in Photoshop. The Photoshop files looks different because its without OCIO but adjusted exposure, otherwise it would be way too bright. Thanks in advance!
