The old "tutorials & downloads" sticky topic is unfortunately broken, and a lot of the links were outdated before that. With your help we'd like to create a new and up-to-date version, but this time we'll be keeping the 2d and 3d stuff separate -- this topic is for 3d tutorials and resources only!
Please post links to anything you think should be included below -- this can and should be anything that you feel is helpful for learning to create 3d art, including stuff on modelling, texturing, rigging, and anything else that might fit. You can find the matching topic for 2d resources here.
Note that this is not a discussion topic, and any questions or comments may be deleted -- we're looking to build a list a valuable resources here! All relevant links will be edited into this first post, and once it's a reasonable size most of these original instructions will be edited out.
