AO Blur Kernel does not work on GPUs, so we get something like Mach bands in the output of AO, would be happy to get it to work on GPUs, and I would like to see the AO Blur Kernel on GPUs.
Justification
Currently, the AO Blur Kernel is only available for the CPU baker. It would be nice to have it for the GPU baker as well.
Implementation Details
The AO Blur Kernel could be enabled by using the slider in the Ambient Occlusion Settings
in the Mesh Baking
window.
