Title: Whiskey tumbler
Post by: stevenchman on 2013-07-04, 11:42:14

Just a quick test.  Wanted to see the quality of glass from Corona and I am happy with it :-). 

So here's the raw render and one with some very rushed post.

I left this running overnight - 8 hours - but still getting some noise.. Any suggestions?

PT+PT Progressive on i7 920 - 2.6-3.2GHz

Just an update/question.  I left this to continue running for a whole day and it went up over 1000 passes, yet there was still a big noise problem.  Can anyone suggest anything?

Can you share this scene?

You should probably post render settings and scene screenshots when asking why so much noise.

Did you adjust the contrast in the post-processing options?

If so, don't do that. It looks like you're getting a lot of black clipping. That'll increase the amount of visible noise.

Thanks for the replies.  I've attached the model with the studio HDRI that I used.    Also attached is a screenshot of the settings.

Yes I did adjust the contrast so maybe that was it.
