I'd have to go for 3dWorld, but I agree with your ideas. It's all very well explaining how to create lightning in Maya for example but I'd much rather really good tuts on the principles of modelling, characterisation, boning, texturing, modifying/writing shaders, hell the list is endless! Articles like this wouldn't have to be real beginners stuff either, I'm sure all but the most proficient 3d artists could learn from really good articles written by the best in the business. Make them really in depth, like half the magazine, it could build up to be an encyclopedia of 3d! Computer Arts mag sometimes has some good articles too but I generally only buy either of these mags for a particular article or something on the CD. Baz
