Color Balance node will not update Render Result in Image Window, once a Keyframe is set.
Threadripper 2990WX 64GB Ram
Operating system: Windows 10 64 bit pro
Graphics card: NVIDIA Quadro P2000
Tested with blender-2.80-25772c9e1d2d-win64
Bug appears regardless of CUDA or CPU settings, same effect in both Cycles and Eevee
bug/ has .blend file bug/images has image frames to process bug/render is output directory for render
- Press F12 to render current image. Notice rendered image in Image Edit window and that frames advance when Timeline is advanced to later frames.
- Move sliders in Color Balance node. Note interactive changes in Image Edit window.
- Set a keyframe for Lift/Gamma/Gain in Color Balance node.
- Advance to later frame and then try and adjust Color Balance sliders.
.. at this point, any change to a previously keyframed value will have no effect in
the Image Edit (Render Result) window. New keyframes may still be set, but the user
is unable to see the effect until after a new keyframe is set and manually
This feature worked properly at and before June 1 (blender-2.80.0-git.b3f96da2e605-windows64)
I use a more advanced version of this setup for movie film restoration. It is very important
to be able to adjust Color Balance sliders and preview results before setting keyframes.
It is possible that this bug is similar to report T66073, but I haven't investigated. The attached file reliably demonstrated this first problem.
The Image Result view (in Image Editor) is also now unstable. Render Result will now disappear
and will not return until program is closed and then re-loaded. Scopes seem unaffected.
