The first bullet point there is important, because it notes that “the majority” of CPU features have been carried over to the GPU. Reduced adaptive sampling overhead: The performance overhead from adaptive sampling with large max AA has been substantially reduced.Improvements to IPR: Many improvements have been made overall IPR experience.Users can now switch between different viewport representations while rendering. Improved viewport representation of Stand-Ins: The representation of stand-ins in the Maya viewport has been improved.axf shading networks as a Maya shading graph. Import shader networks: This allows users to import their.New aiLookSwitch operator node: This makes it easier for users to add different looks to a procedural asset by automating the practice of adding a switch_operator and merge operators at the root of the procedural operator graph.

AxF files can be imported into Maya for use with MtoA via the aiAxfShader.

aiAxFShader: MtoA has added support for Xrite’s AxF file format through a new shader.

Since the majority of the CPU features are now supported on the GPU, with lots of stability fixes and a good match between the CPU and GPU results, we’re boldly removing the beta tag! So, if you want to read all of what’s new, you will need to refer to both the original 4.0.0 release notes (representing 6.0.0.0 core), and also the newer 4.0.1 release notes (representing 6.0.1.0 core).

The latter seems like more of a hotfix that was developed ahead of launch, but is still considered a different version. Something that’s interesting about this Arnold release is that two versions have released on the same day: 4.0.0, and 4.0.1.
