Harry, Here's how I would do it. Load the original object. Create a duplicate of it. Next, create your symmetry mates. Align the duplicate to the symmetry mate of choice. Create a blank movie (eg. mset 1x120, or Movie > Append > 4 Seconds). Now, store the original object's position at frame 1. Then at frame 60 issue: "matrix_copy duplicate, original", and store original's new position.
Let me know if that works for you. Cheers, -- Jason On Tue, Mar 9, 2010 at 2:33 AM, Harry M.
