We will start new VFB shortly. What features do you want to see?
Obvious ones are:
- render history with comparison
- render region
- renderer sampling focus painting
what else?
based on feature requests:
-ability to load Corona exr into vfb
some more wild ones:
-more color mapping/effects (curves, glow, glare,…)
-re-lighting in vfb (re-light/light select pass)
Color correction tools like HSV or curves
I will go with more humble requests.
- add saturation and vignetting to ColorMap tab
- make smiley to turn anti clockwise when rendering interactively, so we can more easily distinguish between these two :]
Maybe an Alpha transparency preview like in VFB+ would be cool.
-
I’d like to have a “normalize view” button somewhere (meaning all colors will be normalized to a 0-1 range). Useful for checking specific REs and highlight distribution in the rendering.
-
even though I nearly never use it myself: loading and applying different LUTs.
Not a feature for Corona’s VFB directly but I’d love to see improved support for VFB+. It would be fantastic if Corona could feed data to VFB+ in interactive mode (which seems not to be possible yet) or if VFB+ could access Corona’s output in every render mode so we can use its feature set directly.
My 2 cents.
I start from this: every static render I do needs to be passet in photoshop (or similar, Adobe doesn’t give me any money for this), for a lot of reasons, often just to give some more contrast or to do some curve corrections, other times to have a more drastic post production. That’s the reason why we need render elements.
I think all post production requests, like curves, vignetting, saturation, ecc.., are kind of post we can easily have in post (I mean in photoshop). Also, I actually prefer to have a “raw” render ready to be edit in post than to have an already edited image. One more, very often every shoot of the same scene needs some different editing, so every setting in vfb should be camera-depending to be significant.
I think developers should be concentrated in other kind of improvement, like region render in vfb, or ability to load Corona exr into vfb, or light remapping or any other tools we can’t have in post.
Peace and love to everyone,
Alessandro

Glow / glare / lens flares (physically based if possible). For example, we get harsh white dots in certain reflections if we use Corona sun/sky, adding some sort of lens based glow/glare would smooth these dots out and give us some usable photographic looking highlights.
-
Some sort of built in color mapping / curve adjustments with save-able presets so users can share them / replicate settings easily.
-
Not sure if this is VFB related but it would be nice to have different forms of tone mapping, like filmic tone mapping or something completely novel and personalized to Corona perhaps?
HOW EXCITING!!!
in order of importance for me:
- render region (and make it better than vray from the outset by adding shift-click to add to the marquee area (like in photoshop selection) and alt-click to subtract. Rectangular selections are fine but i think more complex selections would be AWESOME and so much quicker than having to make a custom render mask like you do in vray. It wouldnt require any additional UI elements at all but would make rendering regions (for small fixes on renders) so much quicker.
- Curves (i’d use this instead of the current contrast spinner)
- Vignetting
- color temp - add ‘tint’ like in camera raw
- lens effects
- filmic tonemapping as an option (adding this in as i’ve heard Juraj talk about it - i still dont know much about it!)
- A Histogram would be useful
EDIT: added number 7
Make it so holding down the render button to select IR doesn’t end with clicking the DR tab since it collapses over it. Just a little nitpick of mine.
i think it will be awesome if we have a tool for make region crop directly inside vfb
Some simple histogram preview would be more than welcome.
Maybe is too much to ask but some zebras for overexposed and underexposed could be great, also an option to superpose one render element over the beauty render to check things, and finally the obvious option to save previous renders and have the ability to compare those renders between them.
Cheers.
I’d like to be able to see 360 renderings properly (something like Google StreetView or other 360 rendering viewers). + for VR camera with the ability to switch between left and right eye.
also it will be great if we have a difference blending mode (something like photoshop) in render comparison , so we can find which things are changed in new render.
It took me a little while to understand where the “clear VFB inbetween renders” was and it was also confusing since the same option is available in the performance tab under interactive rendering.
It would be quite obvious to have this option only available in de VFB display when rendering I guess and preferably unticked by default.
This! It’s a hassle to search for the Clear VFB and then find the right one at that. I don’t particularly care where the option for IR clearing is, but please put a checkbox or something somewhere on the VFB.
Also, +100 for filmic tonemapping as mentioned previously. 
I already wrote this but I was asked to paste this here.
Hi I have noticed some FVB improvements, I would like to suggest one more.
CoronaMap tab, Is it possible to add the “CameraExposure” buttons like those in:
Basic photographic exposure.
DOF etc. In some subtabs there? It would come up handy, especialy the BPE, as it locks the exposure during render.
@@@@@@@
Other thing is that I would like to see this:
