Learning blender, this is not a project of any sorts - just me learning.
I am trying to make a money bill, and I'd like it to have softbody physics, so that I can make a shower of bills flying around, landing on stuff.
I've created a box and scaled it to the approx. dimensions of a bill: ie: paperthin. In the beginning I used the original dimensions, but I read somewhere that if objects are too small, softbody-simulations won't work that well, so I scaled it up quite a bit.
I've then added a photo of the to sides of the bill as a material using UVs.
When ever the bill collides with anything, the backside of the bill get's squished through the frontside. I have to make the bill very thick to avoid it - far too thick.
I even tried to use a lattice as the softbody object, and I've of course enabled self-clipping.
I've fiddled with the size of the virtual balls around each vertex, various combinations of stiffness and even damping etc ... No matter what I do, the backside ends up bleeding through the frontside.
Attached should be two screenshots, one just before the collision, and one just when it happens, you can see the backside bleeding through (with a brownish circular object) just underneath the tower on the right hand side.
How can I prevent the backside from bleeding through the frontside?
