Trying to experiment with the modelling/texturing/rendering to get the correct feel for the paper... which is made up of lots of subtle but important features.
I used procedurally generated textures and bump maps on a tweaked automatic UV, which I think is pretty successful and would save a LOT of time. The only downside to this is that in order to apply any displacement maps for detailed paper wrinkles/tears etc, we'd need to fully UV the model which would be difficult and time consuming.
I'm rendering a 40 frame video at the moment to show how the light interacts with the paper. I'll post that when I can.
