So, I've got this VR/360 scene rendering: the camera swoops into a room and then just sits there for 600 frames. SOme cyclical things are going on, but nothing big.

But the render times are inching up. This is not one continuous render session, it's been interrupted a couple times. But the render was running about 8 minust, and now at f785 it's up to 17 minutes.

Basically, very little is happening/changing, so why would the render times creep up?

This is using GI, if that makes a difference.

Sounds like typical Animated GI cache issue.
The more samples are added to GI cache, the slower to evaluate given spot.

!?!? And this accumulates even between sessions?

Cache is written to disk.

Oyyyy..... ::sigh:: So much to learn. And then re-learn.

Off to read the Unity manual. LOL.
