New VFB features

[Ondra]

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?

[maru]

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

[romullus]

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 :]

[Chakib]

Maybe an Alpha transparency preview like in VFB+ would be cool.

[racoonart]

- 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.

[Edit]
- even though I nearly never use it myself: loading and applying different LUTs.

[pokoy]

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.

White Balance color picker like in Camera Raw



Auto Focus picker like in Octane

[Ludvik Koutny]

I've got an idea. Sometimes I play with color mapping settings, like exposure, HL compression, etc... Or i temporarily need to lower or raise exposure when i go from interior to exterior or vice versa. I occasionally forget the values I settled with and have to search for them again. It would be perhaps helpful if every spinner had a small square S button glued to the left of it. When right clicking this button, current value will save, and left clicking the button will recall the stored value.

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

1. 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.

2. Some sort of built in color mapping / curve adjustments with save-able presets so users can share them / replicate settings easily.

3. 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:

1. 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.
2. Curves (i'd use this instead of the current contrast spinner)
3. Vignetting
4. color temp - add 'tint' like in camera raw
5. lens effects
6. filmic tonemapping as an option (adding this in as i've heard Juraj talk about it - i still dont know much about it!)
7. A Histogram would be useful

EDIT: added number 7

[steyin]

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.

[Siahpoosh]

i think it will be awesome if we have a  tool for make region crop directly inside vfb

[romullus]

Some simple histogram preview would be more than welcome.
