More shadow tests

I decided to do a few more shadow tests as I wanted to make sure I was doing it correctly and since The pillar already had textures done for it I thought I would give baking out the textures on the pillar a go and applying the edited shadows onto the pen texture. The painted shadow texture is quite a subtle effect but it blurs the edges of the shadows enough that it takes away the clean cut CG effect away from them. Also this method cuts down the render time quite a lot.
