Lsscpp (lsscpp) added a comment to D4806: Box-selection in Outliner using Mouse.

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)

Lsscpp (lsscpp) added a comment to T64083: Render border around icons.

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)

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

This is a fantastic improvement, great work.
It would also be useful if Blender could automatically "auto advance" to the next slot upon rendering.

I can't envision a situation where you'd intentionally want to overwrite an existing slot, but one often wants to compare sequential images and forgets to change slots before, unintentionally overwriting the previous one.

Lsscpp (lsscpp) added a comment to D2662: Cycles: Adaptive rendering based on a norm of rendered pixels.

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.

Lsscpp (lsscpp) added a comment to D1281: Cycles: Adding a "No Override Layers" option.

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.

Lsscpp (lsscpp) added a comment to D1132: Cycles: Experiment with making previews more interactive.

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?

Lsscpp (lsscpp) added a comment to D301: Number of samples taken per progressive iteration.

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.

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?

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.

I dare.
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.
