Shadow Catcher Improvements: https://devtalk.blender.org/t/lets-finally-fix-the-shadowcatcher/691

Glad to hear, closing then

Your file work properly. So I check a lot of times my file and I find the problem: I've a copy of the surface without the weight paint and the copy was hide, but not disabled...
So now it work! Thank you very much!

hello all,

OpenEXR reading and writing should use chromaticity metadata to determine the color space of the image, and convert it to and from the working color space.

cannot reproduce here in a simple test scene:

If it is related to Blender, then it is definitely a separate bug. Closing this one.

Updating my GPU driver resolved the issue for me. I last updated them about a month ago, but I downloaded the studio ready Nvidia drivers this time. The issue is also absent from the latest experimental build. Instead the Windows toolbar flashes around the point that the bug usually appeared, but whatever it is that's causing it seems to be handled appropriately now.

You increase the subversion in BKE_blender_version.h, and then use that new value in MAIN_VERSION_ATLEAST instead of 0

I cannot reproduce the issue here. Not sure if this is related; Please check if the same error happens in the newest nightly build and if you can update your GPU driver.

Bigger tile sizes use more memory, especially when using denoising and render passes. If it runs out of memory because of that, it's not considered a bug.

Please try the latest daily 2.81 build, this may have been fixed by rB8f1a55831c89: Cycles: Fix wrong number of threads on multi-socket machines.

@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.

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.

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

Well this is really not a place to ask about blender usage, please use one of these for this:

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.

There is no light in this file...

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

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.

@ dark
i do not use the file browser i load the file by drag and drop

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.

In T68239#758664, @Jacques Lucke (JacquesLucke) wrote:

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

neither in the default viewport tab nor in the render tab, nowhere, but in the lower part of the window

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/

oh, didnt realise that, my bad, thank you for your help. yet I would still like to know what causes the error... is it memory issue than? just curious...

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

because I found this: https://discourse.mcneel.com/t/cycles-finding-the-optimal-tile-size/42276
