Started render, 8 hours later, still optimizing?!
I was curious about the changes to the render engine in 4.6 so I opened an older project and started the render process. In 4.5 it would take about an hour or so to render the image. With 4.6 I started the render, it said "optimizing". After 5 minutes and still no sign of progress I went to bed. Woke up this morning and went to check my email (forgot about the render). When the screen came on I saw DS and it was still optimizing?! I stopped it. I noticed before the pop-up window went away there were some additional notes to the log, but I could not read them before it closed.
Is there something I need to do in 4.6 before I render any more, so that renders take less than 2 hours?
