Vray 5 Lens Effect Render Element

[hartherb_jj]

Hello,

In Vray Next we could choose if the Bloom&Glare is added to the beauty render or as separate render element.
I can´t find this option in Vray5 and it will always be added to the RGB_color element together with the denoiser.
Is it possible to get the denoised RGB and Bloom&Glare as separated render element?

Thanks

Set the VRayDenoiser's mode to "Show denoiser result channel". This will create a separate channel of the denoised RGB result.

guys this is quite unfortunate.
Why to remove the option of being able to save rgb with no effects and isolated effects layer?
what is the reason for this?

[PIXELBOX_SRO]

what do i do when i want to save:
- tonemapped and denoised JPEG without lens effects
- and lens effects solely?

what i am gettign through back to beauty is:
- tonemapped RGB with lens effects burned
- denoised rgb withtout any tonemapping applied.
- ans some weirdly shifted lens effectz layer appearing quite burde out/red/strange

any hints please?

I've talked about these exact same issues... Major rollback from Vray Next. Actually, this must be the most broken feature right now for us in Vray 5. And there's no good workaround. (the only one is calculating the denoise and lenseffects in Nuke, but that requires to calculate all the necessary passes, which increase ALOT the exr size).

Same thing with denoiser, the CC are baked in the effectsResult and not in the original RGB... Major step back for compositing work.

Hello,

Actually in V-Ray 5 the Lens Effects layer always generates the Glare element.
Then if you follow Aleksandar's recommendation set the VRayDenoiser's mode to "Show denoiser result channel" and then save all channels you get:
- the original RGB as rendered
- the denoised RGB
- the glare element

you can then compose them in a compositing application and apply color corrections if needed.

Best regards,

What were trying to say, Yavor, is that the way it is now, there is no way how to render BEAUTY with CC baked in but without LENS EFFECT applied
all i get is when i do as u suggest:
- glare
- origRGB (rgb pass with no CC baked in and NO GLARE)
- RGB_color (rgb pass with CC baked and GLARE APPLIED)...no idea whether this has DENOISER applied
- VrayDENOISER (basically denoised RGB pass with NO CC)

Its missing the most important output - RGB BEAUTY with CC baked in and being DENOISED

its impossible to either get solely GLARE pass or denoised RGB with CC baked in

No idea why is it done this way but its pretty much useless :-/

If you are going to use an external compositing application, then you already have the important parts available as elements. Then after you add them together you can apply the color corrections in the compositing applications - almost all corrections in the VFB have similar equivalents in the various compositing applications so it shouldn't be a problem. On a side note, the curve control has an export option in the right click menu. Additionally, we are already working on baking LUT files with all the corrections from VFB2 so this will be even easier.

The idea behind this is that if you are going to compose the final image in another application, it is much better (and more mathematically correct) to add the elements together before applying color corrections. So for example if you want to do some corrections/compositing in Photoshop:
- you take the origRGB channel - if you don't want denoiser
- VRayDenoiser if you want the fully denoised version
- blend between the two in any way you like
Add the Glare element on top - it contains the lens effects with intensity 1.0. You can additionally boost the intensity before adding the Glare to the previous layer.
Then you add any color corrections on top of all that.

At the same time, if the color corrections in the VFB are good enough for your project, then the effectsResult channel will hold all information of the denoised image with lens effects on top and with color corrections on top of that and you can use it directly.

gotcha Yavor, this however will take some gettign used to

Is there any chance that fopr example Extratex layer woudl get a checkbox to apply the grading to it please? As i am always gettgin pure linear from this pass..
