Germano Cavalcante (mano-wii) reopened T81977: Viewport Texture Limit Size affects Image Editor when rendering with Cycles as "Confirmed".

I can confirm the slowness when rendering Cycles when the maximum texture size is limited (in the Viewport preferences).
I was unable to notice "artifacts" in the rendering result with Eevee, but in fact the final size of the texture is reduced, which was not the case in blender 2.90.1.

Germano Cavalcante (mano-wii) changed the status of T81973: Particle system behaves inconsistently in viewport and render when instance object visibility is disabled from Needs Information from User to Confirmed.

Oops, I misunderstood the problem.
I can confirm that it is different.
And in fact the behavior in the render and viewport should be consistent.

This seems to be fixed now in (the upcoming 2.91) since (4212b6528afb0) - image draw refactor. Closing it now, let me know if the issue is still around.

Both files (frame_changed_post and frame_changed_pre) work in Blender 2.91.0 alpha. I also tested the plugin and it works in Blender 2.91.0 alpha.

Philipp Oeser (lichtwerk) added a comment to T71234: Custom property doesnt update when rendering animation.

However, there seems to be a "one-frame-off" issue if you take a look at this file:


(frames one and two draw the body in the same place, even though its origin already moved -- this could be due to using frame_changed_post though)

In 2.91, it also doesnt seem necessary to read Custom Properties from the evaluated object anymore? (see the following file)
And to fix the "one-frame-off", you can actually use frame_changed_pre in 2.91 without issues:

Hans Goudey (HooglyBoogly) added a comment to T81543: Improve Render Region Border UI (show/hide the control gizmo).

I agree it's quite weird to tie the visibility to the camera selection, since the border works in the viewport you might not even care about the camera at that point.

Well, in order to see the controls, you need to select the Camera (same as the the scene Camera).
[check in code is a bit weak, so if there is no camera as well as no active object, both are the some (NULL) and you will also see the controls]

michael campbell (3di) added a comment to T81183: Crash during rendering of animation.

hmm, i've just noticed something else. The first time this file crashed, even though auto save was set to every 2 mins, there was no auto saves for around about 1 hour prior to the crash. So possibly it's auto save related?

michael campbell (3di) added a comment to T81183: Crash during rendering of animation.

OK scrap that. I've just sat and watched it closely to see at what stage it crashes. It saves files fine, then it crashes halfway through rendering the first view layer of the next frame. So it's nothing to do with denoising or file saving.

michael campbell (3di) added a comment to T81183: Crash during rendering of animation.

I think it might be something to do with the file saving, because in my scene I have a file output node in the compositor which is writing a multilayer exr (only 3 layers), and the main output settings are writing out a jpg sequence. I just tried changing the jpg sequence to a ffmpeg video, and it was able to make it to 146 out of 300 frames, whereas when it was set to jpg sequence it was crashing every time within the first 50 frames.

This time it created a log. I've tried running today's daily build at factory defaults and the same issue is happening. Tried to render this animation 5 times now and it's crashing each time. Maybe this should be escalated? Seems quite severe not being able to render animations.

Yeah, it's such a non-issue and edge case that it really wasn't even worth reporting. lol But I already had the report written, so I figured I might as well let the devs decide if it's worth fixing.

Been dragging for the past few days but it feels like the "Faster Obj Import/Export" is coming along quite well. This project would require me to rewrite this patch in C, I am open to doing that. I will finish up the work I have done on this in the next week and consider this a prototype.

Alex Strand (astrand130) added a comment to D8868: Import/Export: Wavefront Obj Mtl Overhaul (Improved Compatibility and PBR Extension Support).

With deeper investigation it seems that subsurface scattering is another pitfall. It is a little ambiguous what the PBR extension means when it refers to "Tr" as "translucency". So I took it upon myself to put out a well defined subsurface scattering extension that plays well with all software regardless of feature support rather than relying on a hack. This will be a much better solution for compatibility while not dropping support for subsurface scattering. https://astrand130.github.io/astrand130-github.io/obj-mtl/mtl-subsurface.html

It appears modern versions of Maya don't have this issue with ambient/diffuse being swapped anymore. I am going to add compatibility code to handle this on import for older files which may be affected. I would encourage users to report bugs to software that still has this issue: it's a them problem, not a blender problem.
