How to to this. Rolling, puffing, inflate?

Hi all.
I need to do some animation like this:

Maybe someone have idea how they did this?
I have made many attempts cloth, bending, etc. but no good results.
Best.

Pretty simple with mCloth. Just make an object, apply mCloth and turn on Balloon Behavior.
Set the Pressure to zero and play the preview until it settles. Make that the default state and animate the pressure to 1.

Hi DanHibiki.
Thank you for reply.
Yes I did like you says. It works fine.
Here is also wonderful example of cloth using for inflate objects.:

But I also need the first phase of the animation - rolling part.
I try bend modifier but is looking to simple.

Thx.

by rolling do you mean folding the deflated object, rolling it like a ball or rolling it up in to a tube?

So rolling=unfold, unroll. Like unrolling carpet .

that's a tough one.

you can fake it with a series of bend modifiers applied on top of the mCloth. If it's as fast as that it will look good.

Alternatively you can use a series of poles inside the object and set them to Kinetik. That way you can animate them moving and have them effect the mCloth.

Link them one to another and you can animate a fairly convincing roll. Once you get them to the start position it should in theory un-roll properly.

you can also link the edge verts of your inflatable object to a dummy pole and roll it up by rotating it.

Gotta warn you this is kind of tough and often goes wrong. So try the bend modifier first.
