Title: Tonemapping (Vignette): Beauty vs. Interactive Light Mix
Post by: cjwidd on 2021-11-01, 22:33:06

Saved a multilayer .CXR that show vignette OFF in Beauty Pass but vignette ON in Interactive Light Mix pass. I have not seen this behavior before, but I don't recall the steps to recreate the issue. I'm only posting in case this issue has been detected already - mostly looking for feedback.

The only case I am aware of would be using the "2D Pan Zoom" option in 3ds Max viewport while running IR. If you pan farther away from the image center, you will see stronger vignette. This could be described as "no vignette in production render" (the vignette effect is really there, but very weak) and "visible vignette in IR" (because the vignette effect is much stronger farter away from image center).
If it's something else - we will need a scene or a better description to reproduce this.
