So for a bunch of frames I set off to render this weekend, the render time was reported as 46min on a few machines. On identical machines the render time was 1hr ~40min, and later in the animation the same machines that did 46min frames went back to doing them at 1hr ~40min.
The 46min frames look identical to the ones that took nearly 2hrs. Anyone have any ideas on what is going on here?
You may want to check this: https://coronarenderer.freshdesk.com/support/solutions/articles/5000678431 maybe it’s FTH issue?
Thanks, but that’s not it unfortunately, there aren’t any records relating to max/corona etc.
Which version of Corona? :>
1.1
Annoyingly, I don’t think I can even recreate it because the machines that did it in 46min, later did frames around the 1hr 40min mark 
I hope you mean 1.2.
either way, try 1.3 RC1 to see if a warning pops out
I’ll have everything on 1.2.1 on Monday. I’ll test 1.3RC1 on an effected machine later this week and report back
