Pop solvers and Static objects Collisions

[evanrudefx]

Hi,

I have a question about setting up collisions on a static object. My goal is to have a character walking through snow. I have a grain simulation and then an alembic of a character walking. I have my grain simulation setup, now I need to make my character a static object so it collides with the grain pop simulation. I then made my character walking alembic a static object. Now here is my question: I need to edit the collision boundary of my character walking, but how do I know which solver is being used? Bullet, ODE, or RBD? To sum it up, I have a static object being used as a collision for a pop simulation. How do I know what simulation engine is being used to calculate collisions? Bullet, ODE, or RBD?

Thanks in advance

Quite sure it's RBD

I did some testing and I believe you are right. I tried making the collision for my character a square and that seemed to change the interaction with the grain.

thanks : )

You should try make a VDB volume and read that back in the collision
