Post processing (contrast, gamma, luts) OCIO configs in LV

[mohari.mate]

Hi guys, when i load aces ocio 1.2 config and switch to ocio in LV, is there any chance to increase the contrast of the image ? LUTS, gamma, etc doesnt work, only exposure and saturation. Is there any way to postprocess the image ? It would be fantastic. Cuz sometimes it looks flat and dull.

Thanks, Lev

I understand what you're saying, BUT I can still go into a custom AOV group, and tweak to my hearts desire because it's a POST addition - so in short, an ADDITIONAL LUT channel inside the POST EFFECTS tab would yield additional POST control that is external to all of the OCIO response - correct? That's where I would suggest an additional LUT channel be where custom LUTs can easily be generated from photoshop and applied as a post effect. The same way you would from opening to composite after the fact, just inside octane. Inside the imager would infact be a more non destructive approach - but simply put, you want to open up all shadows, adjust color, anything you'd also see from the magic bullet options, you should still be able to do regardless of the OCIO config with ACES and it just saves with an ACES-sRGB output jpeg/png?

Just getting back to this, I completely get what you're saying I'm not talking about adjusting anything in OCIO or to the raw render data, as a POST step and process just like using a custom light AOV and setting it to soft light with a red hue... that effects the color and values post ACES OCIO, my point is a LUT or Gamma tab at the top of the hierarchy for the AOVGs does that not make sense. I can add a custom render layer mask with a value to adjust the black or white output, color, etc all in AOVGs with some layering. You're suggesting adding a few additional post elements isn't an option it's already rendered and these are post processes that effect pixels with already assigned output color transform from the OCIO. The AOV groups do not in anyway effect the render or image itself but are passes composited together the same way you'd utilize them elsewhere. Having a Curve or Levels histogram or LUT input atop of the stack is all im suggesting for additional flexibility.

• Using OCIO Filmic (from Troy Sobotka) provides various "contrast-looks" - I have attached a .gif (I do not know if it will preview on the forum).

As I said before, at the moment using any of custom OCIO profiles like this generate only 8-bit output so this completly ruin any further software montage or post processing. Just like using standard Octane camera post processing.

Unfortunaterly whetever export settings and file type are used it has always only 8 bit depth if custom OCIO settings are used like Filmic Blender or even ACES Rec ones. I will try Octane Standalone maybe this is Cinema 4D issue.

Hi guys, is there anything happening with this thing ? At a curve adjustment lay or at least a lut support would be great for ocio LV look, finetuning the image before rendering is a huge plus, which is available in linear colorspace but not with ocio.
