Hi Gregg,
Interesting Question. If I get this correctly, the final animation should like like a screen capture of your modeling, but rendered in C4D of course.
The problem with e.g., Extrude is, that it produces new geometry and moves this at the same time. If there is only this information, before and after, tehn the can’t be an interpolation. But interpolation is animation here.
Edit: instead of pulling an e.g., extrusion out of a polygon in one step, do only a little step, then pull on the axis many times, each time you get something like a keyframe with the index. Then animate the index—you are aware how his concept of “Steps” in this plug in works, right? However, plug-in support should be given from the developer, so I’ll go with native ideas ahead./edit
Besides Python (or plug ins?) I have no idea how to produce a point for an object over time. Which would be the base for such an animation. The polygon mode is just a mode to get polygons selected to work with. On the end all boils down to the points in a scene. No points, no polygons. (Please add information if I misunderstood you in that)
The idea of animating an object that is build over time, can be done in methods such as:
From the end to the start
Here you model your object, e.g., from a cube to an Horse, by extruding and such. When done, you have all point that you need and go with PLA back to the state of the cube. To make that more comfortable, you store “Key-states” of your model, so you can use theses as guides to push the points back.
Step by step
You model in steps, if you add more points, you make a copy and the new points shouldn’t make a difference from the frame before to teh frame where you switch to the “new” object.
Morph
Similar to version one. With a Cloner Object and Blend /Modify (e.g., Plain Effector) whereby you need perhaps two versions with one always a step ahead or copies etc.
I will go ahead and check out the Magic Mesh information, even I like his ideas and create, I certainly can’t effort to buy everything I like ;o) Edit: I just saw it is for free, so I will check it./Edit
Please share a little bit more about the start and final model if you can (NDA etc…I understand the limitations)
All the best
