3.5beta 2 - vray denoiser not generating all the elements it is supposed to.

[JD3D_CGI]

For some reason, a scene that previously had a denoiser is now not generating all the elements when I delete and add the denoiser to the scene.

It works OK when I start a new scene, but I can't add it into a scene I would like to render for production.

Max 2015 / win 10

Does it still happen if you delete everything from the scene? If yes, can you send me that empty scene to vlado@chaosgroup.com so that we can check what's wrong?

Best regards,
Vlado

Done - email is sent with a dropbox link

Your scene is setup with the old adaptive method - there is a warning for that in the log:



You can switch it in maxscript to the new one with "renderers.current.twoLevel_adaptiveMethod=1", then the VRayDenoiser should generate everything as it should.

[JD3D_CGI]

Thanks. I couldn't see where to change the sampling method.

I think you guys might need to consider looking into the presets system - on the vray quick settings I saved some presets; perhaps these need to be interrogated in light of the new adaptive sampling?

[Svetlozar Draganov]

V-Ray usually displays a notification message when opening scene saved with old algorithm along an option to update it automatically.
You can update the sampling method via the following MaxScript command:

renderers.current.twoLevel_adaptiveMethod=N

Regarding the presets, with what V-Ray version you've saved them initially?

[JD3D_CGI]

Thanks. That script is handy - but it's not the way vray needs to work going forward.

I think it was saved with 3.40, but might have been earlier. Perhaps around the time of the change?

In any case - vray did not check for that old method every time the scene opened. It didn't check for it when you opened the example scene did it?

[Svetlozar Draganov]

The popup notification should appear if the scene is saved with version before 3.30.01.
If the scene is already re-saved with a newer version without choosing to update the settings it the warning won't pop up again.

Hello Svetlozar,
how can I check in my scene, which method is already in use ?

is that command recomended for that ?
show renderers.current.twoLevel_adaptiveMethod

Kind regards
Alex

Just "renderers.current.twoLevel_adaptiveMethod" and enter. The blue value below is the result - 0 for the old one, 1 for the new one.
