Hi,

What's the best way to handle drastic changes in scene charateristics with the new MTLFXTemporalDenoisedScaler?

Let's say a visible object of the scene radically changes its material properties. I can modify the albedo and roughness textures consequently. But I suspect the history will be corrupted. Blending visual information between the new frame and the previous ones might be a nonsense.

I guess the problem should be the same when objects appear or disappear instantly.

Is the upsacler manage these events for us (by lowering blending), or should we use the reactive or the denoise strength mask or something like that to handle them?

Hello,

Using the denoiseStrengthMaskTexture to work around these anomalies appears to be a sensible choice as these areas don't contribute a significant amount of meaningful information to drive the underlying denoising algorithms.

Put another way, these changes are radically "noisy" by definition so attempts at denoising them don't appear to provide significant value, and therefore we can use a strength mask to avoid unnecessary work.

reactiveMaskTexture is geared for particle systems which can appear and disappear quickly.
