Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 451.77
Broken: version: 2.83.5, branch: master (modified), commit date: 2020-08-19 06:07, hash: rBc2b144df395f
Worked: (newest version of Blender that worked as expected)
Short description of error
According to https://developer.blender.org/T80012 , ability to set high amount of samples (above 16) in nodes which use distance tracing to compute the result is an issue, since according to the explanation under the aforementioned task, these nodes are too expensive for any higher value to be used. Ambient Occlusion shader uses also distance tracing, yet the samples value can be set above 16. Therefore it must be a bug.
Exact steps for others to reproduce the error
- Open the attached blend file:
- Notice the AO shader map samples can be set above 16
Result: AO shader map samples can be set above 16
Expected: Based on bug triage staff explanation under https://developer.blender.org/T80012 , no expensive to computer shader nodes should be able to have their samples value set above 16.
