Is there a way to render and animation and get VRay to save out the LensEffects Glare channel, as well as the RGB WITHOUT LensEffects applied? So I have the lens effects by itself to apply in post…
I never seem to be able to make this happen. There has to be a way short of rendering twice, right?
There must be a better way i am not aware of, but in the while you ought to be able to get it done by adding a light select at defaults (i.e. “Full” mode.), with the include/exclude mode set to exclude.
The list being empty, it will include all that’s lit, and won’t be touched by the lens effects.
See attached.
Creative. Thanks.
While Lele’s workaround is indeed working, there is a simpler solution already available: In the Lens Effects settings, enable “Save Glare channel” as well as “create effectsResult channel”. This will give you the following output (no matter if saved manually via VFB or automatically):
- RGB_Color with Lens Effects baked in
- origRGB without Lens Effects baked in
- and the Glare channel with Lens Effects only
By combining the last two, you can recreate the RGB_Color.
However, there still is a caveat to that: Depending on how you save, the channels are named differently. I still consider this as a bug. Don’t know if this is still a thing in 6, in 5 it definately is:
ah-ah! Indeed, that’s when it shows up, on save. 
Nice find Olli, thanks for that!
I am happy that Chaos still listens to it’s users (well, most of the time :-P) because it was still a request a few months ago. If the discrepancies could also be fixed in the future, that would be great. Maybe they already are, I did not check in 6 yet.
with VRayLightSelect remember about adding VRaySelfillumination as it is not included.
