Unsolvable Flickering

[aggiechase37]

I've got a scene that I just can't get to stop flickering. I tried a number of settings changes, and nada. The worst is on the lower left hand corner, on the rim of this connector. Can someone smarter than me take a look? Any help would be greatly appreciated.

Coherent ratio can cause flickering. If you still use it try "static noise". It helps to ride the flickers accordingly my tests. Also why caustic blur=0 ? Do you need caustics? It can cause lot of fireflys and i think that's the reason your making gi_clamp so low. When you use low gi_clamp, you'll cause to cut lighting effect too much.

I tried coherent ratio at zero and still flickering. It seems to be that the faceting of the polygons is showing up. But that faceting is showing up on what should be a smooth surface. The flickering is occurring within the faceting.

What's this object? Is it a small part of a machine? Are you working on real scale?

It's an electrical cable connector. They're normally about 6 inches long.

It seems 100 meters long in scene. Ray epsilon can require an adjustment for big scenes. Or scale down your objects. I can't do test renders atm but these or a bad uv mapping can cause this. These are my thoughs atm.

And you don't need to add a lot of object tags to every objects. It will cause slow downs in plugin. Just use on top of groups if you don't need else.

I'll keep trying stuff. Thanks for the help though. I really appreciate. And please do let me know if you get a chance to solve this puzzle for the ages

I'm hoping to make some test renders on tomorrow. But seems that you choose a hard way to setup scene else of other issues. Lot of indirect light sources, semi closed environment and path trace. Let's see.

Ended up just taking out the geometry that was flickering, and replacing it with new geometry and a new texture that didn't have the noise. That seems to be doing the trick.

On an unrelated note, it's interesting, but with this scene, direct lighting and pathtracing seem to have about the same render time.
