Still a newbie after several weeks! :^(

I didn't specify one part of my original question -- which I still can't figure out:

I can get [pix_record] to work in a patch like this:

[gemhead] | | <input a movie, etc.> |/ [pix_draw] | | <open a save file; "record" and "auto" messages; etc.> |/ [pix_record]

But how do I do something like this:

[gemhead] | <various manipulations> | [cube] | <???????> | [pix_record]

What do I have put in <???????> to feed geos, lights, etc., to [pix_record]? I tried connecting them directly to [pix_record], which didn't work, and I tried connecting them to [pix_draw], which connects to [pix_record]. Is it that geos don't produce pixes?

Thanks.
