THANK YOU VERY MUCH, I have been trying to get this thing done for quite a long time. Lastly, I would like to mention that when "vertex animation" is baked and applied I got a problem with the scale, scale is not rendered in the webplayer , any idea?

Hello! First of all I feel pretty lucky that I am using blend4web at its young years and would like to thank b4w team for "Power Unleashing" work as you like to it :D. I have a problem with simple mesh deforms "e.g. twisting a cube, rolling a paper…etc". I can make the animation pretty well in the scene (I didn't use armature though), and play it in the node editor, however it just doesn't work at all when I run the "fastpreview"!!! I am working on simulating paper-like objects, folding it to look like origami for example and I don't think my only choice is to use a bone for every vertex in the plane to module the paper well ! Here is an example blend file of the problem.
All the good things,
