I've unsuccessfully tried to use the really useful new ArnoldSceneBake node in Katana. On adding to the node graph and clicking scene export, just the bake process started message shows up without any change in the render log or any output files generated.
Tested on a simple scene with one primitive with a monolithic standard surface assigned and a physical sky dome light. Tried exporting as ASS and USD.
Screenshot and file attached.
Not sure where I'm going wrong.
Any help appreciated (maybe a working sample test file).
