Great info, thank you Mark.

To clarify about using .pngs or .jpgs, are you saying Karma does not accept mipmapped .png files that have been processed beforehand? For example, could I run maketx on my .png texture and use the resulting .tx file with Karma?

Hi,

Does Karma expect textures to be mipmapped prior to rendering, or can it auto generate them on the fly? I see there is a "imaketx" tool that shipped with 18.5 . Do we need to use that exclusively, or will it accept .tx files generated with txmake/maketx?

Thanks,
Chris

That was it, thank you. Happy to disable XPU for now, although making my own polar projection with the existing mtlx nodes would be a fun challenge.
