I know what those are. I just don’t understand how you mean to use them. I reread the topic, but I still don’t get it.
I’ve used shrinkwrap before for character clothing. It’s useful for creating clothing. But I don’t see how it will work here. It makes one mesh “cover” another, not take its shape. With a Cube shrinkwrapping to Suzanne it looks decent, but even then its not perfect. Try to shrinkwrap a subdivided Suzanne to another Suzanne with different angle and see how bad it will look.
My objective is to have a silhouette of the second object in the end, but with simple shnrinkwraps I end up with a silhouette of my second object clearly covered with the first object, even though you just see the silhouette.
This is the problem:
(black is the first object, r5ed is the second)
If you mean doing something more than that, then please try to reword your ideas.
I also don’t see how shrinkwrap will work with animated or moving objects.
I mean animating the size of the bones in such way that each part of the shrinking object disappears into the corresponding part of the growing object, avoiding stuff like the arm of a shrinking character moving past the arm of a growing character.
That will be a lot of work. And it looks weird tbh, when the whole body is morphing to a whole shape that seems ok, but when you morph (scale) just some parts it looks kind of disturbing, just tried
Just do it with a ColorRamp in Constant interpolation; much easier to tweak where the threshold should be.
Woops. Yeah, looks better with color ramp. Still doesn’t look much like in that video though…
