Just to let you know, the slight service intermission was caused by me being busy recalibrating at Glastonbury Festival. I went there with Simon, working for Oxfam, which is definitely something you should look into if you like festivals, are skint, or want good karma.
I'm back at the grindstone now. I spent yesterday trying to make fixes to the first 22 shots which I completed for my college final submission. I got great feedback from fellow tube intern Henri Hebeisen (of glowing robot lights and mushroomer fame). Today I've been prepping backgrounds and modelling the last 13 sets. Here's a screenshot of working up the alpha channel for a camera-mapped shot, which I thought looked quite nice.
