Cycles: CPU / GPU difference

GPU renders bright, CPU renders dark in 4.3+

CPU in 4.3+ also renders a lot slower than in 4.2. So it is clearly a CPU problem.

Can confirm here with latest main (compiled with Optix 8.0):

Render: support pixel density in the render pipeline

While talking about "non-square pixels": Will this patch also write the pixel aspect ratio to image files that support it, like EXR? This is currently still missing and would be an awesome addition.

Crashes switching to Shading workspace with non-default max shader subprocesses

I just recompiled after this commit and on Linux Mint 22 with 560 nVidia drivers main still crashes with anything else higher than "0".

Rendering of normals wrong with motion blur / velocity attribute

Thanks @weizhen for investigating this issue. The case I submitted was not about changing topology. It's just a static geometry with motion vectors and vertex normal vectors on the geometry. At…

While investigating another bug with motion blur / vertex normals, I found that this bug report here can be closed as resolved in latest main (maybe 4.1 or earlier, too. But I didn't test this…

Wow! I never noticed before, because I usually export cameras from Blender to use them in comp or Houdini. Not even the focal length is reimported, while both Alembic and USD exported from…

Rendering multiple deformation motion blur steps with "velocity" attribute is wrong and can cause memory problems

To me it looks like the motion vectors of each step get added instead of "subdivided" by the number of steps and then added. On the other hand, when using a motion vector attribute to add motion…
