When I use the Hardware Render Buffer to render out a path animation with Flow Path Object, The alpha channel is ignored even when I select Hardware Alpha. A default black is matted to the background. I have been getting an error message:
Error: Wrong number of arguments on call to flipbookRW.
It was actually working earlier last week. Now I keep getting a flipbook error message. I'd render it with the normal Maya or mental ray software, but the edges get to pixalated. I'm not sure what to do.
