how to quicken an Iray animation in the settings

Toobis

In order to speed things up when doing an Iray animation at the expense or losing some or a lot of quality or detail, what is the best things to adjust in the settings please?

I set path length to 8

Filtering to Mitchell

post denoiser enabled and max iterations to 20 for speedy ones

avoid emissive surfaces if not needed IE outdoor scene

using only dome not scene makes it considerably faster too if using a HDR but no good if you need lights and emitters

You can also use the interactive mode instead of photoreal, since you said you can go with loss of quality. Or use filament. Personally with iray I can't go below photoreal with 128 to 256 iterations for my quality taste, depending on the scene, even using the denoiser.

p.s. Of course these are just the settings. The first thing you have to do is simplify the scene, for example using the scene optimizer addon.

for still images that is understandable but for animations it is less crucial
