Paper (bank note) simulation

[josemendez]

Thanks, much more clear now. 
Probably the last thing to clarify is about cloth settings to make it more similar to paper, not a plastic material. Please check the "video" url in my previous comment I updated after your last answer 

First thing I can notice (correct me if I'm wrong in assuming this!) is that the note seems very large compared to a real note. Physics engines in general - Obi in particular - use real world magnitudes for everything: distances, masses, velocities, accelerations, etc. Unity units are meters, so it would seem your note is at least 1 meter long.

The scale of things plays a huge role in physical behavior: A 10x10x10 cube seen from ten meters apart would appear to fall much more slowly and have less "snappy" movement than a 0.1x0.1x0.1 cube seen up close, despite visually looking identical. In your video the note behaves like a cardboard piece of around 1-2 meters long, which is probably what a real bank note of that size would look like.

So first step imho would be to make the note roughly the same size of a real note, to get "external" behavior (gravity, collisions, etc) right.

Then, the difference in internal dynamics between cloth and paper are very subtle, so it's quite difficult to capture them in a particle based simulation. Probably increasing bend constraint plasticity a bit and increasing solver damping would get it closer to paper-like behavior.

Let me know if you need guidance on this. cheers!
