Thanks for the input. I agree that learning a second program is less than ideal. And, when you consider Carrara has more extensive animation capability already, the extra goodies in Swift 3D v3 might not be worth using a second program and complicating workflow just to take advantage of those "extras". I am hoping to hear from someone who is actually using Swift 3D v3, particularly for the additional rendering effects. I have also posted the question over in the 3D Apps forum. Chris
