Is it possible to take a scene made in 8.5 and open it in an earlier version, like 6.5? For now I need to go back to 6.5 because my graphics card isn't supported by 8.5 and I get a lot of errors and it doesn't let me use the hardware render but I could in 6.5. I'm in the process of saving up for a new graphics card but until then I'd like to be able to use maya and not have a bunch of errors.
