That technique sounds very promising and would be a great way to get my crowd to do the wave. Have you used it for anything?
Glad to help. Carrara doesn’t have any ‘constrain to’ or follow terrain features. So it can be difficult to animate moving across uneven terrains, especially with multiple objects or set formations.
I have only used this method in testing, but it works very well. Replicated copies appear to follow the deformer objects contours exactly. You can also preview the movements in real time using the Move tool(manipulator). No need to scrub the time line or final render to see the results.
I rarely see the assemble room magnet deformer used, probably because it doesn’t have any documentation. Victoria 4.2 figure uses this magnet deformer heavily in Carrara.
This method can possibly be used for things like insects crawling along a terrain or on a figure. Boats moving across an ocean with the waves or objects being diverted in path animations. Let me know if you need more info.
