I've got a lot of flashing going on with my reflections.

I'm creating a walkthrough video in a building model and have a lot of weird flashing going on in the reflections. I've maxed out the samples and have a strong machine to handle the path tracing. I've done several renders with different options, but it happens every time. Here is a link to an example

Any assistance to get a clean render out would be appreciated

Hello ,

Thank you for posting in the community and this is a common question with Path Tracer and you can reference theses previous discussions posts:

Keep in mind you can manually increase the sample by pixel by typing in a value and not using the slider (the max value is 65,536). Did you try with Denoiser off and fireflies off? I see you posted in the Facebook group and you will get good feedback there as well.

Here is a link to a good overview post:
