Quote - With Vue 5 I could save as a PNG and check the "Embed alpha channel" on the save dialog, and I would end up with a transparent PNG with just the rendered object, exactlty what I want. But it doesn't work the same way with Vue 6. I get the exact opposite of what I want then, just the inifnite plane with the rendered object removed where the alpha information was.

I just tried that to make some billboards of some figures and it worked perfectly - that probably doesn't help you but it does work.  That's the way I've always done it.

I didn't have "hide alpha planes" checked though when I did the render
