I recently stumbled upon the Spline Deformer. I think it has big chances to win the prize for most awful explained deformer ever in the c4d help, as it could be really handy for a couple of occasions. The concept is rather easy to grasp, you have two splines, one functions as basis for the deformation and the second one as the deforming/modifying spline. Think of it as if the first one is a path spline and the other one a rail spline like you would use under the sweep nurbs.
In the screencast I show you how to build a small rig, which can be used for example for hand animated waves (just use a jiggle deformer) or cats crawling under the carpet :-)
Keep in mind, that it's most suitable for flat objects, as the polygons get somewhat stretched and don't get deformed good enough for shapes who have volume.
I'm reasonably familiar with the basic functionality of the Pose Morph Tag. I'd used it before with hierarchies and vertex maps all fine. Yesterday night, using it with uv's appeared to be a no go for me.
Couldn't find trails of other people having difficulties with it, couldn't find any introductory tutorials for dummies either, so it had to be that a child can do it.
But me ....
There i was trying to simply edit coordinates and parameters on the texture tag itself to no avail.
Apparently (thanks Scott) you need to use c4d's uv edit tools for that.
So going to uv edit layout makes perfect sense and works just fine.
Already 2 people asked me for more info since i got it to work, so I decided to do a quick screencast.
Still in trouble ?
Make sure you have an editable mesh with a uvw tag !!
And set the Projection of your texture to UVW Mapping of course.
