What does it do in Imager settings? The manual only says:
"Maximum interval between tonemaps in seconds."

Hi JC,

It's the maximum time intervals (in Sec) between two tonemapped images as shown in the tooltip help.

cheers
Kind Regards

I don't understand this either. In what use case or scenario would one change this setting, and to what effect? Can any one give a concrete example?

Octane Render works in a linear curve mode on the camera imager like a post processing effect. So, artist can choose any effect giving the ability to save it right away.

Please check the documentation link to refer the render examples [ https://docs.otoy.com/BlenderH/BlenderP ... Imager.htm ]

So what it is for?
What happens when I increase this to 100 sec or decrease 1sec?

It was introduced in the early v3 versions as a means of troubleshooting problems that users with slow PCI-X speeds were having. In V3 the framebuffer was moved to RAM so the frequent transfers of data to and from GPU were causing problems, even more with baking camera and high resolutions. At least that's my understanding of it. Later they also added options to disable tonemapping for specific GPUs for the same reason.
