collision behavior not realistic

[yananZZZZ]

Hi
I found out that the collision is too stable in my use case. For example, a really thin box drop on a floor, by right it should hit at some edge points and then lie flat. however, my box is standing straight. I know its a tricky problem and there are a lot parameters that can affect the behavior. I just want to get some ideas. things I have tried but failed:

• Increase stabilization threshold.
• make rigid body damping smaller.
• enable eCOMPLIANT_CONTACT and set collision material damping to some big value.
• changing the scene bounce threshold velocity.
• increase contact offset.

What's more, I found out that the friction behavior for mesh interact with other shape is different. it feels like more slippery. Is this normal or there are other parameters to tune the behavior. such as sdf parameters, material parameters or scene setup?

thank you.
