I cover mostly the basics you need to know about, but not so much on how to use them. This is a fairly high-level view of what is possible in CS4, so if you aren’t sure why you should bother with 3D in PS, go check it out. If you know you want to learn and just need lessons or ideas, check out some of my tutorials on CommunityMX.
Last week, I presented to the User Groups and Community Experts on 3D in Photoshop CS4 Extended. It seems to have been pretty well received, and I finally have a link to post here for those who would like to see the recording.
