POP Network and Particle SOP (following translating geometry)

Recommended Posts

Hi guys,

I'm working on a project where I have to generate smoke like effect to define a character's movement. So taking alembic export of the animation, and converting the mesh to particle interaction within the boundary of the mesh.

I'm doing some test with simple sphere where particle interaction happens inside a moving sphere. I got some problem where after birthing all the particle inside POP net, it doesn't follow the translation (or rather deformation) of the mesh.

What I wanted is generally represented with particle sop where the particle are birthing and interacting within the sphere even when the sphere is moving around. I just need to get the same behavior inside pop net.

Does anyone know what I'm missing? I tried using collision inside pop but that means interaction within the surface of the mesh and not really what I wanted,
