Corey Barker has an awesome tutorial over on planetphotoshop.com that demonstrates how to recreate the Iron Man 2 logo the new Repoussé feature in Photoshop CS5. The tutorial does a great job of showcasing Photoshop’s growing 3D toolset, and reinforces that there are more and more things you can do without needing to rely on a dedicated high-end 3D software package like Maya.
