Making GI Sampling Identical Between Viewport and Picture Viewer

[adploshko]

Hi,
I'm testing out NPR styles that incorporate GI lighting. I want to be able to achieve the look I want in the viewport and have it be identical in the picture viewer so that there are no surprises. However, each time I render in the picture viewer, the result is noticeably different from the viewport result. I believe that the GI sampling is the culprit as it seems to change on each render.

Is there a way to make the GI sampling consistent between renders? If it's not the GI sampling causing the issue, how can I make the renders remain identical?

I've attached screenshots and the project file below for reference.

Thanks

*EDIT: I keep getting an 'error' message when trying to upload images. But the results can still be reproduced and compared in the project file. *

Hi adplosko,

The editor-view IPR for a fast preview. If you like to have something reliable, use the Picture Viewer.

They might come close, but the data is different; it depends, of course, on your monitor and how much you can see.

Render in the editor view. Then use the
Editor> View> Send to Picture Viewer.

Now render directly to the Picture Viewer,
Click to see the Histogram. Can you see how different both are?

Yes, you pointed this out already. But did you see that huge of a difference? In other words, a little more is going on to set the IPR up for speed and the Picture Viewer for quality.

If you think that this, while it is since over two decades so case to be a bug, please check with tech support
