So, I was looking with passionate interest for people who were interested in making realistic materials - called shaders - for Poser mesh. That interest had shifted to making dynamic cloth for Poser, but has since moved further afield: to Blender3D. And creating scenes in Poser for Cycles.
How can it be the best things in life are free? Blender 2.63a with Cycles is just the most amazing programme, evah! How can this be free? Well, what I'm typing in: Linux Mint (based on Ubuntu 12.04) is also free. Solid, stable, never any issues, finds new devices without me having to do anything... how can this be free?
These are exciting times indeed, and they don't cost money. They cost time and imagination and dedication and a desire to learn. And they are free.
