« Last post by piotrus3333 on Today at 09:07:44 »It would be nice to have your resolve/fusion workflow to see how you manage to create those LUT's... ;)
Between the -1.2 string, the "log" option in the vfb lut, the AgX ocio and DCTL (that i managed to install in resolve+fusion), the custom color correct node, well...it gets a little confused ;)
So when i color edit a 32bit image with Agx and dctl, i have trouble exporting to a lut to have the same result in the corona vfb
well,
feel free to ask the Corona Team why things are so convoluted with luts in CIE and frame buffer: https://forum.corona-renderer.com/index.php?topic=40988.0;all
if you're on 11.1 - you can use Gamma Operator 0.455 before LUT operators and the rest of invisible gamma transforms is cancelling itself out. no need for string option and this would work in CIE as well.
Fusion exports luts only for closed domain of 0-1 float, same as photoshop and most lut tools.
Easy way of doing that in Corona is Highlight compression 999 (Reinhard tonemapper x=y/(y+1)) - it acts as your log encoding - raw render is compressed into 0-1 range and lut can access those colour easily.
So in Fusion after creating hald image you need to apply reversed Reinhard on it, convert to arri logC3 and then AgX DCTL >>> and you have a lut that does Reinhard to one of AgX DCTL displays.
what are you trying to create exactly? a macro from Fusion is of no use if you do not know the math behind.
