Distributed Render blur/distortion

(1/3) > >>

mikerogers74:
So when I render locally all is good. When I use DR I get distorted/blurry regions. These occur when the node synchronizes to the server. I am running same Max (2025.3) and Corona 12 Update 2 on both machines. I have tried the lock/unlock render view trick I read about in another post. Attached are samples of with & without blurriness.

Thanks

Hi,

This looks like a clear bug.
Please send the scene over so we can check.

You can as well do this through ticket: https://support.chaos.com/hc/en-us/requests/new

Thanks Aram,

I have literally stripped the scene back to nothing.... a plane with a material with a png feeding displacement and a camera with environment lighting. And still the issue. Zip attached.

Some more things ... I have identical NVIDIA studio drivers on the two PCs, system unit setup the same. Not sure what else to double check.

Oddly, using a Noise instead of a Corona Bitmap to drive displacement does not cause the issue. When I add CInfo_NetworkRenderDebugging I get blurry results

I don't see how it could be a bug with such a simple scene?

Avi:
I am unable to reproduce the issue on my end. How many passes did you render it?

TomG:
Just observations to go into the bug searching

- Since it is the middle third of the image, looks like something to do with sections of the image rendered on one machine vs. another
- It looks less like blurriness and more like ghosting, it's as if three or four versions are overlaid each slightly offset
- Does changing the synch interval and/or max pixels to transfer at once make any difference? Either resolving it, or changing where it happens in the image? The end render is very large so there could be something to do with the network itself getting overwhelmed with data (what is your network speed btw?)
