Hi Aqib, just to be a bit nitpicking...
Right now how can Blender tell if you're boxselecting or click-selecting a single object? From the gif it looks like you have to box select not starting from an icon, otherwise it will trigger the action of grabbing the icon and move the object into a collection. Right?
But we need to visually tell that, and it could be done with mouseover highlight: with the new blue selection those circles under the icons become redundant and useless, so they could be used on_mouseover to alert that you are going to "singleclick+grab" instead of box-selecting.
(Hope I was understandable)

Instead of opacity wouldn't it be better to choose a solid color? This way we could also select a light rim for dark backgrounds giving a sort of glow to icons. Opacity instead forces us to have only a shadow. In case the user doesn't want a rim it should be enough to set it to the same color of the background to make it "disappear"
I have a little concern, being a Gaffer addon user: all mesh object that have an emission shader in the nodetree are shown in the lights list of the addon (T-panel blender 2.7x). Do you know if this new feature of the principle shader will make every material appear in that list? (making the whole addon useless)

Couldn't it automatically detect mono or color PNG and in the latter case disable the colorization?

Nice work Pablo! I wonder if this could sneek into the remesh modifier...

Is there a reason why compression factor isn't exposed to the user? link

I see @Okavango (Okavango) needs, they are common.
A cheap way to accomplish what he asks without making big structural changes would be having the ability to "seal" or "unseal" a collection. Then selecting any object in that collection would select also all the others, so that - selection wise - a collection acts as a single object

What is the scale of the scene? I mean, how one of those squares on floor is big? 1 BU?
It would be great if one could set the scale of the preview, to se how mataerials react at arbitrary size
Nov 2 2018
As i posted somewhere else, shouldn't the tab order of the properties panel have scene and renderlayers swapped? (as it is in the "breadcrumbs" in the header)

I like the design a lot. Now that we have this "First launch setup" layout, I think it would make sense to have an homonym operator somewhere* to call it anytime.
*edit: in preferences?

After further investigation, an information that might be useful to devs: set any bump/normal map node to zero strenght and you'll get the plain artefact, a black circle at grazing angle. Something that reminds me of wrong fresnel behaviour.
Jul 22 2018
I agree for the same reasons. That was an old idea. Yet a stronger separation wouldn't hurt
Jun 26 2018
Labels going back in the fields?
Jun 25 2018
D looks more logical to me.
Everywhere, beginning from right, you have: state, little padding, value field, little padding, label.
In the special case of checkboxes, label is not aligned with other labels. But hey, it's a special case.

Would something like this be viable to reduce clutter and to give a better separation for customizing UI?
May 30 2018
Why? I don't get it.
As on calculators, writing long numbers keeps the cursor on the right hand and expands the digits on the left. Sounds like a trivial matter of right alignement to me, maybe i missed the point
May 17 2018
Maybe instead of a "V" you could try using a circle/dot checkmark. Usually radio buttons are displayed like that.
May 16 2018
Just for the sake of consistency, how do you visually communicate in popovers what options have a radio-button behaviour instead of a checkbox one (on-off)? Currently the all have checkbox appearance (you are allowed to think that e.g. you can enable multiple falloff or pivot-point).
May 5 2018
Wouldn't this deserve its own popover in the 3dview header? It could actually be opened with M-key, like layers used to, since afterall this is a new empowered version of layers
May 3 2018
Yes! nice! and when you close your detached popover (an X is needed), the next time it will be back in its original place under the header
So far it's not possible to have the old wireframe viewmode: transparent faces+wireframe.
Now, assuming that an additional shading mode (transparent) can be added, we would then have to perform two (mouse movement+)clicks to achieve what now we achieve with one Zkey press.

Ideally the adaptive sampling should take color management into account indeed, though in general it's unknown what kind of image transforms might be applied in compositing. A simple color_scene_linear_to_srgb() or sqrt() might already see a noticeable improvement.
Jun 29 2017
Frankly, all the tests look absolutely gorgeous, not just the headlights :)
What I miss is a comparison at same render time: plain vs adaptive.
The original render takes hours but deciding what is 100% quality sounds arbitrary here.
One thing I didn't understand: is the check done at pixel level or at the whole tile?
May 22 2017
So I understand that Norm here is a sort of threshold, right? Then, setting Norm, is like setting the "main level of smoothness" of the image.
Could this include a time-halt condition?

I found a weird shading bug for wide surfaces. It behaves alike when using procedural texture for bump mapping or in displacement slot

Occasionally testing this branch (build 26e906d) it appears to have a major bug rendering SSS with Branched Path Tracing, as shown in pictures here: https://blenderartists.org/forum/showthread.php?403342-Cycles-Disney-Brdf&p=3162218&viewfull=1#post3162218. Basically branched takes care of base color only, as if it is ignoring the SSS color input.

I think that a feature like this would be better than making two or more renderlayers and compositing just because two render layers mean two different renders in a row, which means more time. I don't know how blender works under the hood, I imagined that with material override there's some "switch material" at the end for every object, so I thought that it would be easy to just mark some objects to be excluded from this switch.
Hi Lukas, great to see you giving some time to this, thank you a lot!
As posted on BA, there could be another option for this, that is having the override driven by a group instead. What do you devs think is more appropriate?
Apr 6 2015
Sorry if this can be seen as a feature request: currently the rendered preview redraws on *any* change happening in the node-tree even if the node added/removed/changed is not connected or evaluated (mix=0/1 conditions). This is sometimes annoying since long and clean previews get cleared (and slow the system down while re-rendering) while one is making some node operation that don't affect the final material appearance.
For the sake of this kind of optimizations, do you think that this can be addressed?

Hi, being a former Maxwell user I can say how much progressive refine can be useful, giving you the chance to stop the process anytime and have a full-frame render anyway. The plus in Maxwell is that for each step it actually writes a temp image, to keep the job safe in case of a crash or power failure.
Oct 17 2014
Hi Lukas, regarding the UI debate, what about adding just a slider named "AA samples multiplier"? It could come along with a text exposing the evaluated total, as well as how it happens in the bottom of the samples panel when you enable branched path tracing.
Also, I don't know if the word Confidence comes from the papers or from some JND/MonteCarlo/math-related glossary, but for us final users wouldn't be Convergence or Smoothness more obvious?
Oct 13 2014
Sorry, I forgot to mention, the behavior is both in GPU and CPU rendering
Jul 8 2014
Still i can't see benefits in my daily usage ...probably beacause it's not clear to me what this patch is actually doing!
Jun 24 2014
Anyway. How can Blender users have a try at your patch?
Hi, I'm quite interested in these adaptive solutions.
How do you manage to avoid visible tile boundaries in a low sampled render?
Using (entire)tile stop condition easily lead to have adiacent tiles with equal threshold but visible difference in terms of noise, as I experienced with the other experimental method developed by likas.
Jun 10 2014
About me asking earlier if it was possible to have per-pixel stop-condition, I thought of a workflow like this:
May 8 2014
Yes indeed, my tiny test showed way lower speed gains. Indeed almost no speed gain for bit-noisy renders. But this is probably my fault.
Do I read well: now your CPU rendering is 4 times faster than GPU... instead of 8 times slower??
This means 32 times faster in CPU/CPU comparison!! Or in other words, 3200% speed boost, or also rendering in ~3% of the time!
Ok, let's say that I misunderstand something here...
May 5 2014
How hard - if ever possible - is it to implement per-pixel stop condition?
Apr 17 2014
as m9105826 says. test could be done on a more difficult scene as this: http://www.blenderartists.org/forum/showthread.php?331149-The-new-Cyles-GPU-2-70-Benchmark
Lukas, what is actually the difference between "adaptive stopping" and "adaptive stopping+sampling" ?
Apr 10 2014
IIRC LuxCore implementation uses max error inside each tile, and it sounds reasonable too. This way you always know how much the error might be.
Can't wait to test this out. Can you (ora anyone) please upload the build once it is ready?
Apr 5 2014
There is also one more opportunity: time halt condition. To make this possible the engine should know how long each tile takes to render, so a first pass (with a minimum sample number to be decided) should be done for all the tiles. This would give two benefits: a proper render-time estimation, and a first rough look at the whole render output.

@Jason Clarke (jtheninja)
I actually don't know ;)
BTW, Yafaray has something similar since ages. Wondering what is the noise-aware implementation there...
And it's what I've been waiting for a looong time... :)
Mar 31 2014
Yep thumbnails are better than nothing, but often i feel the lack of a good (big) view of textures (Not to speak about the time needed to see all the thumbnails in a crowded folder.). So I have to reach the folder via system and search the images with an external app (a trivial viewer). Having a view that is fullsize and scrollable would be a gift. A thought this because Blender already has its own viewer
Mar 26 2014
Any chance to have a preview area in the file browser?
Feb 21 2014
@Lukas Stockner (lukasstockner97) no, unfortunately i have no clue about performance
@Jason Clarke (jtheninja) can you please make another BMW test with no adaptive, letting cycles run for 3:03 as well, so we can see how better the algorithm distributed the samples in the same amount of time?
Feb 20 2014
I actually did a search... Google this: "entropy based adaptive sampling paper"
Wow! Can't wait to test it (whenever a build apparso on graphicall). About more advanced difference predicatore, i remember i posted somewhere a link to a paper named something like "Entropy variance". That could be something worth to look at
Feb 16 2014
Regarding difficulty vs remaining noise, what about the idea shown here? (http://blenderartists.org/forum/showthread.php?236453-Measuring-Noise-in-Cycles-Renders&p=1985872&viewfull=1#post1985872)
