apparently, one of the ideas behind allowing viewing and manipulation of 3D files in cs3e is that it speeds up the workflow. I think the guy in the video (excellent work by the way) said something about not having to shut down photoshop and start up maya (or something to that effect) in order to see the changes in the texture on the model itself. however, assuming the guy made that video using standard techniques, and didn't cut out frames during video edit, the video shows the real-time effects of changing the texture, then viewing the change on the model. going with this assumption, I had photoshop open with a model's texture, and carrara open with the model in the texture room. I edited the texture in photoshop, saved it (a time-consuming step that is still required in cs3e), then switched to carrara (OS X dock). it took about 0.5 second longer to click on the dock, then click on the "reload texture" button in carrara, than it did for the guy in the video to switch to the 3d layer screen. but in either case, the result is the same. hence I think cs3e is an excellent app, but not certain the extra $$$ is worth it, if it only saves me 0.5 second in workflow.
