I ended up using Irradiance Cache for primary (with a custom sample count of 200) and Light Mapping for secondary.
I had a very subtle camera push and very subtle object animation, so I want to test my current settings with more extreme animations.
Yes, I did have GI Area Light selected for all polygon lights.
You are absolutely right about the light fixtures. At first I had polygon lights, so no amount of sampling would get rid of the spotchyness (even in when rendering stills). But I used Cinema lights and it worked great.

In case anyone is interested, I think I’ve figured out what settings to tweak.
I started with the preset “Interior – High (High Diffusion Depth)” which uses IC+LM. And the physical renderer.
I found the most important parameter to be Path Count under LM. I doubled the default (from 10,000 to 20,000) and that cleaned it up a lot.
I also changed the Record Density under IC from “Med” to “High”. I used a custom Sample Count of 200 (under General) because I don’t really understand the % increments. I find it more intuitive to use custom sample counts.
I also enabled “Build Radiosity Maps” under LM to improve render time. At least I’ve read that this setting improves render time. I want to experiment with it and see how much of an effect it has and if my system can handle it.
Finally I upped my AA from Med to High (just for funsies).
A 1280×240 frame it took me just under 2mins to render, which I think is great. The image is 98% flicker free!
My machine has a Cinebench score of 690, so I can afford using higher settings, but you could probably use lower AA and Record Density settings and get away with it. I’m creating video for a giant theater, so I need very clean renders, but for web video, I think this is amazing.
I’ll post my renders in a bit, but I’d love to hear other people’s experience working with the new R15 GI.

I tried using Stitch and Sew, but I think I had a lot more vertices on one shape as compared to the other, so it made Stitch and Sew freak out. I had to go in a do it a bit more manually, but I eventually got close to the look I wanted.
I’m trying to make a wax seal, and have gotten pretty far, but I’m running into some sculpting and texturing issues.
As you can see from the image, the base layer near the bottom rim is not flat, so it’s catching the light in strange ways.
Is there a sculpting tool to flatten in out?
Obviously the base layer should be totally flat, but it has a number of undulations that Smooth just isn’t taking out.
I’m also getting weird texture issues from the mesh. It’s most pronounces around the upper magnet area. There are waves that make the Bump look strange.
And suggestions on how to fix that would be much appreciated!

That worked great! Sorry for the late response. Appreciate the help.

Wow! That took the wrinkles right out 🙂
Thanks so much for your help Adam. I’ve seen your posts on some other threads in the forum. Really appreciate your contributions to the CC community!

Ah ha! That was exactly the problem. Thank you Mato. I shan’t make that mistake again!

Thanks for the suggestion. However, I tried turning Open GL off and it didn’t help. I also played around with the various settings but it didn’t help.
The problem seems to be with this particular composition. I just remade the comp from scratch, applied the same effects in the same order, and dropped it into my main comp with no problems. I have no idea why the dot cloud appeared, but I was able to rather inelegantly workaround.
In any case, thank you so much for your help!

The white rectangle is in a pre-comp. I’m sorry – I should have been clearer about that.
The dot cloud appears when I apply the drop shadow to the rectangle inside the precomp and when I apply it to the precomp itself.

Changing the refresh rate did the trick! Thanks so much!
I’ve never ran into this problem with FCP because it was easy to alter the sequence’s codec and frame no matter what codec and frame rate of the original clip was. Of course then you had to render, but that seemed like a small price to pay for such flexibility. I’m a bit disappointed that PP doesn’t have that same functionality, or at least doesn’t offer it with the same level of ease.
Anyway, thanks again for your time and help!

Thanks Buck. The problem I’m running into now is that I can’t match my settings exactly, so my footage looks blurry. The only way I can get my sequence to exactly match my clip (for example, its frame rate is 30.3 for some reason, even though I set it to 30 in Snapz) is to drag the clip into the Create New Item icon.
When I do that, I can no longer change the frame size. Have you ever run into this before?
