ncloth deformers in rigging?

#1

I’m not sure how to ask this, because I don’t know the terms, but this is what I’m looking for:

Imagine a marble, or any object of any shape, rolling under a piece of cloth, like cockroach under a carpet. What I’m trying to do is to have a controller for that cockroach that I can slide it along the mesh and it will be morphed into that shape. I want to use this in a character. One of the uses will be in the eyes brows because there are some facial shapes that I want to achieve with it, and the other use is to have the character playing with his tongue under his cheeks rolling around.

Does anyone know the term or the solutions for this?

Thanks in advance!
cheers

Since you said ‘nCloth’ so I guess your in Maya.

Try wire deformer.
Draw curves along your rolling object on both side -front and side.
You’ll end up with something like a cage that follow along the contour of ur object.
Now select your cloth object(should have quite a lot of subdiv if you want to maintain details on the shape) hit enter, then your curves, hit enter again.
Maya will create duplicate of that curves called baseWire curves, which are hidden. The effect of this is calculated by the offset of each pair of curve(the curve you drawn and the baseWire), so, unhide those base wire scale it down on Y axis till it flat to the ground. Now, you’ll see that your cloth is bulge up, you might wanna adjust the drop-off values on the wirenode to widen the effect. Group your curves and baseWire curves together. Move that group around, see the result.

You can apply something more to the curves like sine deformer, bend, flare, blendShapes or pretty much anything!

This can be apply to use with facial deformer like that tongue under cheek like you mentioned, too.

hope this helps, excuse my English.

I’d just go for a sculpt deformer… I don’t really understand what you want to do with the eyebrows, but for that tongue and cheeks thing, it seems to me that it is what you need
(create deformer > sculpt deformer)
