LONG pause during 3Delight render

JonnyRay

I have a simple scene. One figure with clothes, hair, and a pair of wings. Three basic spotlights setup in a Main, Fill, Key configuration. When I render using 3Delight, it starts rendering as normal, does several buckets in the middle of the image (using spiral). Then, around 45 seconds into the render it will pause. Nothing is getting rendered at all. If I let it sit, then around 10-11 minutes later it starts rendering again and the whole thing finishes less than 4 minutes later.

I just built this machine last winter so I'm sure it isn't the computer causing the delay. I've tried removing the wings and other items, but nothing seems to make a difference. There's a long pause for nothing and then the render finishes relatively quickly. I'm stumped.

The log file seems to tell me nothing...

Update: I increased my bucket size and it seems to be focused on the skin / body of the figure. The buckets which rendered the wings and clothing went quickly. The ones that got stuck were the ones working on parts of the image where his skin was showing. I may fiddle with the skin shader tonight.

Such pauses as that I usually associate with transparency maps on hair and some wings.

There's a pause when the render first hits a bucket with a surface with SSS - or rather each time it hits a surface using SSS and a different Group ID value. If the mesh has an HD morph the pause will be substantially longer.

I thought that pause (to do with AoA SSS) took place 'globally' at render start

No, or not unless it is a new behaviour. You are, however, right that transmapped surfaces will also slow the render down - but that applies to every bucket they are in, the SSS pause happens only once per GroupID.
