Hello everyone,

I'm making a shot that consists dam breaking and the water coming out.
I've cached the the dam breaking and now I'm trying to have that same cached geo to collide with the water.

I'm doing this so I could save a lot simulation time.

I cached the geo using a rop output driver using .bgeo file format. I then tried bringing in a file node, brought that cached geo and tried using it as a collider. But I'm having troubles of it working.

What is the proper way in bringing cached geo (of the dam breaking), and using it as a collider for the water spewing out?

Thank you for your time and help in advance,

just use your dam geo cache as a Static Object
make sure that:
1. geometry is unpacked
2. has correct v attribute
3. check Use Deforming Geometry and uncheck Use Volume Based Collision Detection in Static Object
4. set flip/Volume Motion/Collisions/Velocity Type to Point

Thank you for those pointers, they definitely helped me resolve the problem.
