Filmic or AgX from Blender EXR to Natron or Fusion

when you save your render from blender as exr you retain all the scene values and multiple render passes but the safe color space will be linear so we'll lose anything you set up in the color management tab if you put normal image in later on it will convert it from srgb to linear the output will convert it back to srgb after the composition our exr is already linear but wasn't converted from srgb use the Ocio color space node to direct the compositor and convert it from srgb to linear yourself before that we have to pretend we are blender and make the srgb from the linear but using filmic agx or whatever connect Ocio look transform before the color space node filmic is already in Natron input should be a linear look whatever you are using in blender and output filmic as RGB from display menu if you are using something else like me you have to provide the different config file for Ocio for agx the settings are the same input should be linear if you see an error there just choose anything else and set it back to linear look again whatever you are using probably Punchy and output agx base from imagery menu one more thing to solve is the exposure important note the nice 32-bit values to modify live before the look transform now anything after is a standard 8-bit image that means we have to edit the exposure before the loop transform simply modify the image by some value the multiplier is exactly 2 to the power of the exposure my case the exposure is 1.2 2 to the power of 1.2 is 2.2974 so I will multiply it by that another note if you are using Fusion there is no multiply or exposure node use brightness contrast note the gain option is exactly what you are looking for that's the multiply put the 2 to the power of exposure there this is it nothing more just two Hammer the point home let's try an example of combining track footage with overlay render my output settings are ajx punch a with exposure of one and the exr contain combined layer ambient occlusion and Shadow catcher I will use Shuffle to find the shadow catcher blur it by just one pixel and multiply it with the footage then I will shuffle for the combine pass and do the trick multiply it by 2 because my exposure was 1 and 2 to the power of 1 is 2 look transform with agx Ocio config linear input punch look and agx base output and conversion from srgb to linear finally shuffle for the embed occlusion with the alpha of the combined pass multiply the combined path blur it a bit again and merge it as overlay over the original footage done just remember this is only a rudimentary setup without any actual composition so start here and go wild before Loop transform you have all the values after just a set 8-bit tabs hope it helps thanks for watching and till the next time happy blending
