Short description of error
EEVEE Next viewport render (
Viewport>Viewport Render Image) always look like 1-sample render, regardless of viewport samples setting.Viewport render with 64 samples:
It seems it actually does sampling but always use the same noise patterns.
Viewport render with 1 sample (zoomed in):
Viewport render with 64 samples (zoomed in):
Short description of issue
RenderedViewand pressViewport Render Image- Note that the resulting image has 1 sampleViewport Render Imageagain - the resulting image has 2 samplesViewport Render Imageagain - the resulting image continues to have 2 samplesSeems, that voxel size is fixed in screen space, and it is quite rough. Not sure if I would call this a bug, seems more like TODO item to me.
In addition to volume voxels, this report also mentions viewport samples (which soften shadows, volume, edges...).
I'm not sure how these samples affect Viewport Render, but the current behavior does not seem to be as expected.
So I'm confirming for now.

I think this was caused because some object types caused the renderer to reset every frame, which was fixed a while ago.
In any case, the issue doesn't seem to be there anymore, so I'm closing this.
I checked in again and the issue doesn't seem to have been fixed.
I noticed that the steps to reproduce the problem were missing. So I added it.
Apparently for
Viewport Render Imagethe steps are limited to 2, I don't know if this is somehow expected.In EEVEE Legacy, the greater the number of steps, the longer the viewport render time.
@mano-wii Thanks for adding reproduction steps.
Yeah, I don't think this is fixed.
Final render (64 samples):
Viewport render (64 samples):
Oops, sorry. I've missed the Viewport Render Image part.
I'll check.
