sticking particles to the animated emitting surface


stripes

Recommended Posts

I need to stick several million particles on their animated source geometry at the exact point where they are emitted from and follow the geometry's (emission point's) position. Please guide me towards any resource that might explain this process clearly.

best regards

Easy. Read up on the scatter node help section. It tells you to take a look at the output attributes. Turn on "Prim num attribute" and "Prim UVW attribute" Next freeze your scatter with a timeshift node. Freeze it at your first frame. Next lay down an attribute interpolate. Plug your first input into your scatter frozen scatter node. Then plug the second input into the mesh you scattered your points on. 

 

If your points are inside the geometry it is different but pretty much the same. You would use a point deform node for that instead. You don't need the attribute interpolate node. Only another timeshift node.

Any questions don't hesitate to ask.
