3D texture tests
I wasn't sure how to make the jars for my animation, I wanted to attempt to make them 3D if that was possible so I tested some textures to see if I'd get anything close to what I wanted. None of the shaders however were giving me the effect I wanted and I wasn't sure how I'd add an outline.
Flash Jar test
Because Maya wasn't giving me the effect I wanted I decided to try testing the Jar in flash instead. This gives a much better effect but because things created in flash can't be transparent I'd have to composite things on top of it.
I did a quick test of it here.
