A while back I bought an ebook by Robert Burke on modelling in Blender. Although I’ve done quite a bit of modelling in the past the later versions have added extra features and I used to use pretty basic techniques anyway.
I’m learning quite a few useful tools and techniques. At the moment I’m working on an exercise to model an iron spiral staircase, probably Victorian style, and it could prove a very useful model to have for various scenes. Quite a lot of detail, will be interesting to see how he achieves that.
