Task to keep track of reproducible bugs until we merge into master.

  • #91055 (indirect diffuse pass bug) (was by design and to save GPU state memory but may be reconsidered)
  • #91024 (Turning Cast Shadows in Light Settings off makes makes dark glitches.)
  • Missing OSL attributes (see TODO in osl_services.cpp)
  • #91279 (Mist pass not compatible with SSS)
  • #90848 (Cycles-X: render difference (visual surface imperfections))
  • CPU uninitialized memory with AO node
  • #90010 (Cycles X - Any SSS color below 0.025435 becomes pitch black on GPU)
  • #91429 (Cycles-X: Persisitent Data does not allow for the changing of sample counnt.)
  • #91441 (Bump node isn't working as planed. We need to Bake it so it works.)
  • #91427 (Cycles-X: Viewport display is distorted upon render finish with adaptive sampling and a non-one pixel size.)
  • #91426 (Cycles-X: adjusting viewport render settings in a certain order can result in the viewport turning dark)
  • #91431 (Blender crashes when switchin between GPU and CPU rendering devices)
  • Baking does not work with auto tile
  • #91425 (Cycles-X: OpenVDBs render differently between CUDA and OptiX)
  • #91590 (Baking specular does not use smooth normal for view direction)
  • #91428 (Cycles-X: Spring demo scene shows large performance regression )

Bug reports to be closed when merging into master:

  • #90734 (Fully transparent material creates light bounces)
  • #89353 (2.93 - Cycles Volumetrics - GPU and CPU results look inverted (Distance vs Equiangular sampling))
  • #80267 (Large scale volumetric object with large step size causes rendering artifacts on CPUs in Cycles.)
  • #91479 (Rare effect on shading)
  • blender/documentation#77185 ("Noisy Image" pass not matching "Combined" pass is not well documented.)

Just thought I'd add that #80267 (Large scale volumetric object with large step size causes rendering artifacts on CPUs in Cycles.) and #89353 (2.93 - Cycles Volumetrics - GPU and CPU results look inverted (Distance vs Equiangular sampling)) can also probably be closed when Cycles-X is merged with master.

I was asked by @ThomasDinges to post a collection of bugs/regressions in Cycles-X here. Some of these have been reported before on other sites, but they are not officially being tracked anywhere in the public so I have reported them here.

#91425 (Cycles-X: OpenVDBs render differently between CUDA and OptiX)
#91428 (Cycles-X: Spring demo scene shows large performance regression )
#91429 (Cycles-X: Persisitent Data does not allow for the changing of sample counnt.)
#91427 (Cycles-X: Viewport display is distorted upon render finish with adaptive sampling and a non-one pixel size.)
#91426 (Cycles-X: adjusting viewport render settings in a certain order can result in the viewport turning dark)

I found a new bug with the latest cycles version #91431. I causes crashes when switching between render devices.

A bug for Cycles-X was reported here that you may want to take a look at: #91441 (Bump node isn't working as planed. We need to Bake it so it works.)

I was asked to make a bug report for Cycles-X I found just to keep a track of it. It can be found here: #91476 (Cycles-X: Changing "Start Samples" in denoiser resets viewport render)

A report that should be closed when Cycles-X is merged into master: #91479 (Rare effect on shading)

This report can also be closed with the Cycles-X merge with master as NLM was the cause for this issue and is no longer in Cycles-X blender/documentation#77185 ("Noisy Image" pass not matching "Combined" pass is not well documented.)

Unless there are plans to return NLM to Cycles-X in the future?
