Marcin Twarowski (Tvaroog) added a comment to T64727: Baking normals cause strange noise.

Highpoly object has a material called None.003. It has an empty texture material node attached to normal.


When I disconnect it it bakes properly. Here's another test file. A monkey with an empty normal texture node. When you switch to rendered mode, you can see that the normals are wrong.

Marcin Twarowski (Tvaroog) added a comment to T63297: self-baking normal map problem.

Here are test files for 2.79 and 2.80. Both cubes have auto smooth at 30 degrees. If you press bake you can see that results are different. 2.80 bakes normal map as if it tried to transfer normals from smooth version of the cube onto the sharp one. Exact same thing happens with edge split modifier.

It bakes clean when camera is far from the volume. But I think it gets bad if the viewport camera is inside the volume. Here you can see two bad probes:


Here's a video with probes visible. You can see how screen glitches when camera is inside the volume. After first bake there's a bad probe in the corner. After second bake you can see the same probe is now good.

I've just updated drivers to 419.67 and the problem remains. It doesn't happen in every scene, there's something about this particular combination of objects and materials that causes problems. If I replace material of the tiles for a more simple material there's no flickering. Perhaps related to the other bug I reported: T62742

I just noticed, that even when you mix two separate identical shaders there's still a difference in brightness. You can see that in the video in 00:25 on the lower right corner of the box, there's a slight variation in brightness. EDIT: What is going is the second shader ignores Screen Space Reflections. If you turn SSR off they both look the same.
