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

Hi.
You don't really need to use RBD solver for that just turn on Use Deforming Geometry option in static object (your character in this case).

I found out that it is using RDB after much testing. Use deforming geometry I already have on. You need that for animated geometry.
