A really cool new feature in After Effects CS4 is the ability to now take advantage of Photoshop CS4’s new 3d capabilities. Another new feature of Photoshop CS4 is the ability to open .kmz or .3ds files. If we take a look at the extensive free models we have on Google’s 3d warehouse we find a ton of models to choose from. If you can find the model you want on the 3d warehouse as a kmz you are in luck. Open the kmz in Photoshop CS4 and save it as a psd. Import that psd into After Effects CS4 as a composition making sure to check the box that says “Live Photoshop 3D”. Now you have a new composition in After Effects with a 3D model as well as a null to control it and a camera to pan around it. If you can only find a skp of the model you want on the 3d warehouse, you will need Google Sketchup Pro to export that model out as a 3ds or kmz. Open the 3ds or kmz in photoshop save it as a psd, import that psd in After Effects and you are set.
