System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 457.30

Operating system: Windows 8.1
Graphics card: Nvidia GTX 1650

Blender Version
Broken:

2.92.0, 2.91.0
Worked:
2.90.1

Short description of error
Bakes are nearly blank / transparent when the Progressive Refine option is enabled, as if the samples are not properly accumulated.

Exact steps for others to reproduce the error

Create a file for baking or download example file bake_without_progressive_refine.blend below
Verify that it properly bakes to texture
Enabled Render Properties > Performance > Tiles > Progressive Refine
Bake the texture again

bake_without_progressive_refine.blend

bake_with_progressive_refine.blend

The result should look like a very faint image of how the actual baked texture should look like.

I've tested this and couldn't find any problem. The file below was created in 2.83.9 and bakes fine in 2.91. Does this file work for you?

bake_2_83_9.blend

Could you please upload a minimal example file that works for you 2.83 but doesn't in 2.91.0?

Thank you for your quick reply!
Yes your file works as it should in 2.83.0 and up, I can recreate this type of minimal baking as well and all is good. I think the issue must be in the baking of selected objects with textures to active object texture or I my process is set up incorrectly and my files work accidently?well.blend
I apologize for the file size but it is the smallest file I have with baking.

@l.leonard.dadx2 Thank you for the file. I will look into this tomorrow.

Don't worry about the file size, 12 MB is completely fine. We just always say minimal because some users upload production files >500 MB. This complicates identifying the relevant parts to reproduce the bug and unnecessarily occupies storage on our server.

I can reproduce some odd results in 2.90.1, 2.91.0 and 2.92.0 with your file that do not happen in 2.83.9. I'll have to investigate this further.

For my own reference: There have been issues in the past that should be fixed (#77298, #78072).

Observations:

Opening the file 2.92, creating a new texture and baking to it, results in a very faint, almost entirely transparent results. When switching the bake type to normal map, the result is cut out similar to the #78072 examples.
Appending the collections to a new file in 2.92 allows to bake, but the result is darker and there appears to be more (self-)occlusion
- Append all collections
- Enable Bake > Selected to Active
- Set Extrusion to 0.152
- Set render samples similar to original file
- In the World properties enable Ambient Occlusion with Factor set to 0.5 and Distance to 10 m

Thank you for looking into this. After applying your suggestions I did see that it did in fact bake in 2.91.0, just nearly black. I can get some color and clarity by changing some lighting settings such as the Background strength to 500 in the World tab or adjusting the Exposure in the Render tab, still unfortunately with unusable results.
I just tried baking a beveled edge and textured cube to another cube in 2.91.0 using the same set up process I use in 2.83.0, this is not baking at all.
bakedBrick.blend

A bit off topic, I see that 2.91.0 only utilizes my GPU as low as 10% and only up to 60% while baking and rendering, whereas 2.83.0 utilizes 99%.

This appears to be caused by the Render Properties > Performance > Tiles > Progressive Refine option.

Robert Guetzkow changed title from ~~2.91 and 2.90 not baking?~~ to Baking broken when progressive refine is enabled
