At the moment in my teaching I am introducing a class to a whole bunch of new stuff to do in Maya, and like clockwork I have noticed the little comments starting to creep in about the program preventing the students from getting the work they want.
This kind of thing makes me wish we could lock students away from all computers for the first few years of their animation life. Not because I want to save them from the frustrations of using software, but because I want them to realise that their short comings have nothing to do with software and everything to do with experience.
My first animation job was at a completely digital free studio, everything drawn by hand, photocopied onto cel, painted with real paint and shot on film. Even the line testers used video editing stations.
Just as I am introducing my students to new things, those teaching me at Disney were pushing me way out of my comfort zone. And just as my students are discovering, I often found that my work lacked the polish, precision or appeal that I hoped it would. But because I and all my peers and teachers were only using paper and pencils I had no one to blame but myself. Its pretty hard to blame your lightbox for a bad drawing.
Its normal for your work to be sub par when you are trying things for the first time (or even 10th time), its been that way since long before computers were around. If you can see your work could be better that is a good thing, it means your eyes are being opened to the potential in a situation, that you will be aware of ways you can do something better the next time. That is of course as long as you accept the responsibility instead of blaming some external factor.
Make no bones about it, every time you blame a program for poor factors in your animation it is a lost opportunity to learn. Every time you blame something else you give yourself permission to blunder on the same way a bit longer, instead of asking how you might improve your approach or frame of mind next time. When you sidestep the responsibility you also sidestep the changes that have to happen within yourself if you are going to grow and develop as a creative individual.
