Alex Strand (astrand130) added a comment to D4971: added emission strength to the principled BSDF node..

@Brecht Van Lommel (brecht) I have some questions. I'm working on the defaults improvements as suggested by @Carlo Andreacchio (candreacchio) using versioning_cycles.c but I'm not sure what to set MAIN_VERSION_ATLEAST() to.

All conflicts should be fixed and this patch has been made ready for merge to 2.81.

Sam Mousa (Mrqozy) added a comment to T60094: Render crash when using Python API to modify object data in frame_change_pre handler.

please fix this!
flip fluids is a must for any water sim in blender, the internal fluid simulation engine is a pain.
its a shame blender devs haven't fixed this bug already.

Philipp Oeser (lichtwerk) added projects to T67829: Cycles shaders show up in EEVEE list (Properties > Material tab > Surface panel): Rendering, User Interface.

It is also the other way around (you can e.g. see Shader To RGB in cycles), so it is a general issue of uiTemplateNodeView I guess

I have attached a jpeg of what im seeing on my screen. I circled in red the point that i want to cast light and the values of it. I want shadows to be cast on the figure that I created. Thank you for looking into this for me.

Is this a bug? Do you think an uninstall and reinstall would work?

Sam Van Hulle (sam_vh) updated subscribers of T68926: Color Management Improvements.

Great to see that the wiki document made it into a task. I would like to suggest this task to be made a parent task of all other open tasks regarding the subject. It's great that this task is finally here - it would be even better if we make it an overview of everything else. Then at least we have a bird's eye view on the scope of what needs to be done.

Brecht Van Lommel (brecht) added a comment to T68239: Cryptomatte affected by Color Space change in OpenEXR multilayer..

I'm not sure if and how this is handled by other software using Cryptomatte. Presumably there would be some metadata on the OpenEXR pass, or the names of channels are different than RGBA indicating that it is non-color data? We should try to match whatever the standard is if possible.

Stefan Werner (swerner) added a comment to T68239: Cryptomatte affected by Color Space change in OpenEXR multilayer..

If I understand it correctly, the cryptomatte passes should never be modified by some color space transformation. Is that correct?

IMO internal GPU problem as memory or maybe too data to elaborate or so, however this is not a forum or chat, this is a Bug Tracker.
To make some chat Blender related ,you can use https://blender.chat/home #support or #today channel for technical discussions you can go in https://devtalk.blender.org/

your link is 2 year old and is related to Cycles to Rhino, Cycles had have a lot of improvement untill today, best tile size for Cycles in Blender depend on many parameter, for my porpuse best render tile size is 64 and my Workstation never had crash related to this render tile size

This problem is already reported many time from other users, to try mitigate your issue, upgrade your GPU drivers to latest availble from Intel site as already request, however Intel HD Graphics 4000 GPU and older not meet minimum Blender 2.80 and newer requirement

Abid Maqbool (cto.abid) added a comment to T68829: Blender crashes each time I switch to rendered mode in shading viewport.

Then you should try latest graphics drivers (form official site)...
I am unsure prob is caused by gpu drivers but could be... even one function could be used form latest drivers to fix some problem during migration of daily build/RC3 to stable one....
Also try with load factory setting method

@Abid Maqbool (cto.abid) it worked well in builds before the official release on the same time so I don't the problem with my graphics card.
I edited the task and give you more info.

I think, your graphics card not works well with Blender.
However, try installing latest Graphics Drivers From Official Site
Also we need every info to understand the exact problem, simple From Blender itself Help -> Report A Bug

michael campbell (3di) added a comment to T68823: GSoC 2019 - Cycles/EEVEE Improvements.

As EEVEE doesnt support object motion blur, a vector pass would also be a great addition to EEVEE if possible. Would save having to render each frame twice (once in eevee and once in cycles for the vector pass).
