curtain model

[Acies]

This is how I would do it:
Apply a texture. Then create your animation. Go through the animation frame by frame. If anything looks odd (stretching or unnatural movement) do some weight painting - that particular frame will change before your eyes. Soon enough the animation will look natural. Save it then.
Edit: Forgot to add: Once done go to Skin--> Edit Smooth Skin--> Normalize weights.

Step two is to skin-->go to bind pose then export the object (without animations).
