lenseffect not working with mask (neither matID or ObjectID)

[fraggle]

Hello,
I'm trying to applied a glare only to the candle flame.
I assigned both ObjectID as well as MatID but none is working using the mask.
I add renderelement for ObjectID and MatID just to make sure there was no problem with the ID. I can confirmed the renderelement render fine with just the flame.
It works fine without using the ID mask, but as soon as the ID is turn on it doesn't work anymore.
Same behaviors for glare or for bloom.
Vray 4 (next), last version.
Any idea?

After some test, I discovered that the render mask is not interactive. Each change on the Object ID need a new render.

Yes, it needs a re-render. Not sure if you will like this or not, but for the V-Ray Next update we have removed the Object ID/Material ID controls; instead there is only the intensity threshold. This allowed us to reduce the memory usage for the lens effects and to speed them up significantly. They are also reworked from scratch so they should work better in general.

Best regards,
Vlado

Good news, because it's really slow on large image and mask can, most of the time, be done in post prod.
