viewport and gpu compositor rgb curves difference

laplace diff between viewport comp and main comp

shouldn't the one being shown by the image editor (view node) be the same or similar since it too is going through the same scale node?

HSV in viewport compositor give different result than on CPU.

one last thing. Other compositors allow out of gammut colors as well in their working space. They just give you options for the mapping. Input and output would have mapping options with a good…

Hue correct node does not match other hsv nodes

If you make colors outside the rec2020 gamut then there will indeed be the same problems as well. The compositor should make it difficult to generate such out of gamut colors in the first place,…

Hue correct node does not match other hsv nodes

One more video using agx this time. Similar situation happens with aces config.

Hue correct node does not match other hsv nodes

Added a video to show the problem. In the video by adding an hsv node before the huecorrect node I get the same color output as the hsv node, but before that the huecorrect is giving bad behavior.…

Hue correct node does not match other hsv nodes

the same issue happens when using an aces config and agx config with rec2020 working space. should not get different results from adding hsv, hue correct, or separate /combine hsv when none of…

Hue correct node does not match other hsv nodes

This is the type of graph I have to build to work around the the saturation and color shifting issue for the hue correct.

Hue correct node does not match other hsv nodes

as with my other bug report, this clamping will be more of an issue with aces and agx; maybe a clamping button like the mix node or delaying for blender 4.0.

HSV in viewport compositor give different result than on CPU.
  1. neutral hue correct node gives different results to neutral hsv

2.)all those node nodes show color shifts when using aces or agx configs

for number 1 , bring the neutral hue correction…

@omaremaradev the issue with the clamped saturation, can that fix be applied to the Hue Correction node as well? It would be needed for both viewport and cpu compositor. It would allow me to…

HSV in viewport compositor give different result than on CPU.

Did some more test on my end to find out why I was still getting shifts. Everything seem fine visually with blenders default color config, but when using agx from earychow or troy I can see the…

added a smaller blend file to make it easy for anyone one else who looks at this.

hvs node changing input colors with viewport compositor

did some quick test for completeness.

colors come through from color correction node and yuv mixer group

  1. hsv node (bad on gpu, good cpu)
  2. hue correction node (bad on both)
  3. hsv…

I only made a diff bug report because they were diff nodes
