I want to do some old-fashioned raster-based animation, in a program which imitates cel animation. In other words: I want a program which will let me import or draw a background, and import or draw line artwork (which will appear as transparent layers, except for parts that are inked or painted in) for each frame. Oh, and for Macintosh. :P I've looked at Flash tutorials, and it doesn't quite seem to be what I'm after. Vector stuff.... I thought I might be able to do it in Photoshop, but now that I'm learning it, it doesn't seem right for the purpose. Painter has animation features, but not set up to do what I want. The folks who make Lightwave have just released the ideal program (Aura) but it's beyond my budget. I have found lots of programs that sound okay, but they refuse to tell you on their websites what they cost or what platforms they are for or what the system requirements are, so I am simply assuming they cost a fortune and are Windows-only. The only way to find out is to register to download for a demo, and the last thing I need is spam from twenty more software companies who don't make anything I can use. I have just given up on the personal (free) edition of Animation Stand, which seemed ideal, if the manual wasn't written by an utter cretin. (I swear, when I tried to do the tutorial, at least three times I was told to do something, but not HOW to do it until pages later, and twice told to do something which was not actually a feature of the program, and then when I goofed up doing something that was poorly explained, the frikkin' program crashed!) Does anyone have any suggestions for me? Help!
