Korben, if you don’t want to use the wheel animator script that is fine, it is not required. The main purpose it serves is to keep the drive wheels in sinc with the tread, but if you can do that without the script, then by all means go ahead. But, once I add in accelleration into the scripts, I think it will be a lot harder to keep it in sinc without the script.
And yes, you can copy the hierarchy. However, on certain links (such as the one I used in the tutorial) that have gear-like protrusions on the side this will not work because the links needs to be flipped about the Y-axis, in this case I think the easiest method is just to reposition a copy of the link and re-run the tread builder.
That being said, I’m glad you do like the results and I hope to see some tanks and stuff using my scripts <!– s:) –><img src="{SMILIES_PATH}/icon_e_smile.gif" alt="
