No lens effects and glare

[Makushimu]

I don't know why I don't get any glare and lens effects. In VFB2 glare channel is black.
I have spot light sources on the ceiling and the scene is additionally illuminated by HDR
I think, that in older vray5 releases this worked normal. I'm working on the December 10 release

Hi Makushimu

Can you let me know how the lights are done/what type of lights are used in the scene? Lens effects should be working just fine, are you sure all the lights are enabled? If you disable them and re-render, are you getting the same results?

Might be a good idea to forward us the project so we can investigate further - you can do so by reaching out to us though our contact form. Make sure to mention this thread in the email.

Some time ago, lens effects worked in the same configuration as in this scene.
Dome light from HDR + area lights or sphere lights. Previously, with the HDR alone, the lenses also worked.
Sphere lights are used in this particular scene. On a ceiling.
All other render settings are default, I use auto exposure but also no lens effects without it, I tried different aperature settings.

....
I found it.
I've noticed that lens effects don't work with color mapping set to exponential.
I have a feeling that in earlier releases it worked with any color mapping.
With reinhald lens fx work fine. I did not check the other color mappings.

Thank you for clarifying. The effect is based on pixel values, using Exponential will clamp the color values which will result in low intensity on those pixels - they can't be read; I'll actually make a note for this to be added in the docs as well. You can use Reinhard and control it with the Burn value - if set to 0.0, the result is the same as Exponential. Values between 0.0 and 1.0 will blend the two types (Reinhard/Exponential).
