Hey Guys!! I'm testing a setup filp, I would want to collision the ball. However, no effect appears....I've also attached the scene file, hope someone can help me figure this out..

Thanks a lot

You have to use the Populate Containers (tab) > Collide With Objects button. (or create it manually).

FLIP don't care about RBD's or Bullet.

Switch your Velocity Type to Volume in the Collisions tab on the FLIP solver. You'll need to increase your substeps too.

As a tip.

 

If you dont have deforming geometry to collide with. Keep the animation att object level and uncheck the use deforming geometry.

That way DOPs will only calculate the collision SDF for the RBD once and transform it.

VDB is fast but if you dont have to, why calculate it every frame?

here is what i did, to make collisions work in your scene

 

1.in the flip solver > volume motion tab > Switch your Velocity Type to Volume

2.in the flip solver > particle motion tab > switch collision detection to particle

3.i also did some simple rewiring in sops.. u can see it in the scene file i have attached

 

thanks
