Alex P (eneen) added a comment to T50458: Hosek/Wilkie sky model weird coloration.

I think it's related:
Luxrender currently has option for custom ground color, really nice feature for larger scenes where there is need to model plane to hide sky leaking from ground. It works independently to albedo.

christian brinkmann (poor) added a comment to T47530: Proposal: Animated Render Border Attributes.

Thanks @Dalai Felinto (dfelinto). I posted that as a proposal, because I wasn't sure whether someone else noticed that behavior - realized later that something like this is bad practice. I'm sorry.

Note that this only happens with Cycles render engine (i.e. new shading system), not with BI.

Dalai Felinto (dfelinto) closed T47530: Proposal: Animated Render Border Attributes as "Invalid".

Design tasks are reserved for developers willing to implement a feature. This is not the case. It's a feature request in fact, which we don't accept in the bug tracker even though that is a nice feature request (along side with "multi-border" render). That said, Blender read those values at render init to prevent crashes coming from users change the data (e.g., render border) while rendering is happening.

Marcin (mj3017) added a comment to T51290: "Display the image in Stereo 3d" may increase render time drastically.

I don't have knowledge to give you proper answer. All I know is that when this options is active render time is much longer, but result is exectly the same.
In my opinion it would be good practice to switch this option off during rendering process.

Stephen Swaney (stiv) added a comment to T51290: "Display the image in Stereo 3d" may increase render time drastically.

Is this a bug or simply the fact that "Display image in Stereo 3d" is computationally expensive?

Brecht Van Lommel (brecht) closed T21410: Render API load from file does not load all layers as "Archived".

This is still a To Do item regardless of the amount of user interest. The render API was never designed for this purpose, and the network render addon is currently unmaintained.ware

@Brian Cary (brinux) We're working on an addon to fix this, anticipate that the fix will be integrated into our addon end of June this year. Feel free to contact us if you'd like to test. We got snagged on this problem too but found there is a way round it, but it involves programming, so we're building this into our addon which does network rendering.

Using 2.78c and just bought four new computers to use as my "render farm" and then found out from personal experience that network rendering ignores the compositor (tears) - and this has been broken for at least SEVEN YEARS?!?j

@Thomas Nzioki (code4eva) please open a new bug report, resurrecting a 3 years old one is not really a good idea, especially since you are not under the same OS etc. Also please fill all required data in report (we need hardware specs among other things…).

Sergey Sharybin (sergey) closed T49248: Blender crashes when try to render a simple scene as "Archived".

So it is now confirmed the issue was a threading conflict. This situation will be handled totally different in 2.8 branch, so no real point trying to address this in master at this point.

Joel Godin (FloridaJo) triaged T51318: Non-update of preview when switching from world to lamp panel. as "Confirmed" priority.

Yep, after moving from World to Lamp, keeps World preview until you make a minor change in settings.
Suspect refresh upon focus is not the same as refresh upon setting change.

I apologize if this is posted in the wrong place. This *seems* like a bug. Using Blender 2.78.4 which I used instead of 2.78a/b because prior to 2.78c IK was broken and causing crashes. i will test on 2.78c asap.

Sergey Sharybin (sergey) claimed T51007: Material viewport mode crash on node with more than 64 outputs..

The issue is coming from hardcoded MAX_SOCKET set to 64. I've tried to remove such a static limit, but it's not so trivial within the current nodes design, especially for the texture nodes. I think it is safe to bump this constant to 512. This will only be ~16K extra stack memory usage per thread during evaluation which is really small for the modern systems.

This is the same problem as in T49921 - the normal mapping changes the surface normal, so the reflected ray would go inside the actual geometry, which isn't really possible.

Lukas Stockner (lukasstockner97) added a comment to T51023: MixRGB node still keeps in memory both input textures no matter what "Fac" value is..

The problem here is that you have Clamp enabled, which means that the Node is actually doing something (or rather, would do something if your textures were HDR).
However, there's no real reason to keep the full MixRGB node in the SVM code if only a clamp is needed, so I'll add a separate clamp-only SVM code.
