New vray framebuffer doesn`t apply adjustments to render elements.

[M.Max]

Looks like you don`t fully understand what you are talking about. seandunderdale is totally right about all layers being complete trash in VFB2. That`s why i started this topic.
Overexposed layers without all corrections applied are totally useless in postproduction. VFB1 worked well in this case. I rolled back to old VFB in vray5. Glad it`s possible.
I hope somebody from dev. team are reading this and "fix" this in some later vray version.

I totally Agree.
The problem here is that there is 2 workflows, I've worked with both sides in the last 15 years and I totally understand why linear passes are crucial for some people ,but on the other side it is almost the standard way for most Archviz artists to use tone mapped passes to do the post production work, especially for stills.
So yes, it is needed feature indeed and would be great to have it back again without workarounds that could "fix" this, but cause other issues as I've stated earlier ...

Not sure if I got all this right but if I apply tonemapping etc with denoiser present it will only be applied to the effects channel? Right now that's a problem for me too since I like to mask denoiser and use it only on the walls and not on the fabric or wood objects since it kills their details. Now I can't do that since RGB is not tone mapped.

Yeh it also sounds like having more than one effects_result would be useful. An effects result of everything, but also one without glare, one with denoiser on etc. This should be the default that all of these are included, but it would be awesome to have them as options to turn on.

Just to get this right: There still is no convenient way to save the corrections in the framebuffer to the render elements?

If this is true, it means V-Ray 5 is still not ready for our automotive workflow. Nearly a year after it's release. For us, it is essential to have that functionality.

[seandunderdale]

Unless Im missing something, no there isnt. A solution for tonemapping the passes and getting lens fx to work has been helpfully posted on another thread, but if you use filmic tonemapper or any other grading tools in Vray 5, your passes wont get that backed in, as far as I know. Only the effects result has those changes baked in, but if you use lens fx, thats also baked in, which is annoying if you render in deadline. I would love to be corrected and put right, if anyone knows better.

There is a workaround. You can save everything in vrimg. Do your edits in vfb save current channel as one exr, then for instance hide denoiser channel save again current etc. It's a bit slower but not that bad and you save tonemapped version each time. At least it seems like that now that I tried it.

This sounds like a hack-job. Also, we are mostly using Backburner for rendering with DR, so this solution falls short.
I'd like to have back the behaviour of the old VFB: Display the elements with all corrections, save all elements with correction, as specified in the correction (LUT for example, save in image).

[kosso_olli]

I'd like to get back to this: Will there be a way to do this in the future?

[matanov]

Yes, it's planned.

[kosso_olli]

Thank you. Any ETA on this?

Any update on this? I tried saving the color corrections from the LUT, but it doesn't achieve the same result in after effects as what the VFB shows. I've only been able to get the color corrections to show up if I use the denoiser element, but then that flickers a little because it's frame by frame. I haven't been able to figure out a good process to achieve color correction (curves, exposure, white balance) in an non-denoised frame, with a separate glare element. If anyone can help me out here, that would be great.

We're holding off upgrade until this is resolved.

What would be the workflow with animations?

See below from another thread;

Hi,

This has been discussed before, but I can't find the relevant topic so I'll post it here to see if there is a known fix.

We are currently rendering an animation and baking the toning into the beauty pass as that is our prefered workflow. I realize a non baked workflow would be better, but that also creates more steps in the process. Especially when you can get the result needed out of vray. In older vray versions the toning was saving in the origRGB and the RGB_colour (beauty). This worked well for us as we could decide between the original image and the denoised one and blend between them where needed.

However since, maybe Next, this function was disabled and for us the origRGB was a useless pass. Normally this isn't an issue because we work with stills and we just save from the vrimg in the VFB a couple of versions of the beauty (toned, toned + denoised & toned + glare). This gives us enough options in post.

But, now we are doing an extensive animation we are losing both the toned version and the glare version. We are now only working with a toned + denoised pass. And the denoiser isn't always cleaning up everything as needed (or an artifact here and there) and we now can't mask that with the base toned pass as that doesn't get created. We will have to fiddle about with toning in the video editor instead which isn't optimal.

How can we get the 3 beauty passes (rgb toned, rgb toned + denoised, rgb toned + glare) without rendering 3 times....or having to do everything in a 3rd party software package based on a non baked workflow?! Am I missing an option somewhere?

We are currently rendering the animations and will be doing so over the weekend so if anyone has some info it's welcome! Thanks!

Added to the thread, how do you deal with wanting a beauty with and without lens effects to comp later?

This is something Ive been banging on about for a while, with no luck.

Glad it's not just me then. I find it strange that even the option isn't present. In the VFB a simple "tick" to bake toning into the passes would do a lot. And for the glare / denoised passes it could just be an option in the render elements dialog.

Add a denoiser pass = rgb denoised
Add a lens effects pass = rgb + glare

It's practically already set up in the VFB with having two "layers" to turn lens effects and the denoiser on or off. Just add an effects pass for both.

Done.
