Bloom and Glare

Hi all

Just wondering why the output window reports a repeat of Bloom and Glare, instead of applying the post effects once at the end:


[2017/Oct/10|11:59:31] V-Ray: Noise threshold lowered to 0.000015 with 4.6 percent active pixels.
[2017/Oct/10|12:00:14] V-Ray: Noise threshold lowered to 0.000008 with 4.6 percent active pixels.

And does each 'bloom and glare' pass include a noise refinement/increase in image quality?

With progressive rendering, we update the post-effects (denoiser, bloom/glare) periodically during the actual rendering. We don't seem to have exposed the option for controlling this in the UI, but you can use the following post-translate Python callback to force the update only at the end of the rendering:

from vray.utils import *

p=findByType("SettingsImageSampler")
p[0].set("progressive_effectsUpdate", 0)

You can set it to other numbers between 0 and 100 to control the frequency of the updates.

Best regards,

Thanks Vlado.

It's not a biggy for us, so no worries on having the feature exposed.

Thanks for the code. Do I run this in the Script Editor before setting off a render?

[vlado]

You put this into the post-translate Python callback text box in the Common tab of the V-Ray render settings.

Best regards,
Vlado

Cool, cheers.
