Is this the correct product to make a bean bag? - jimmyriggs - 24-10-2020
I would like to make a 3d bean bag. I've read about soft body physics but all of them I've seen pop back in shape. I want the bean bag to stay out of shape

Hi,
It depends on what you want the bean bag to do, how you want to interact with it, what platform you're targeting, and what ms/frame budget you're working with. For a simple softbody effect, I'd recommend having at least 1 ms/frame to spare.

This is called plasticity, and is fully implemented by Obi:

I'd recommend taking a look at Obi's manual/docs before deciding if this is the right tool for you:

Note that traditionally, bean bags, pillows, mattresses and similar deformable items that are not the main focus point of the game have been simulated by using 2/3 rigidbodies and a couple joints. This remains the simplest/most efficient way to do it.
