Is there a way to confine particles to a mesh? I've attached an example of how I'd like to be able to get the lava to flow down the side of a volcano. The paths are just curves converted to meshes to show the flow path..
In trying to get the particles to follow a mesh, I detached a part of the volcano in Max, then imported it into Houdini. Treating it as a collider, the particles just collide and randomly fall off the mesh. Is thee a node or a network in Houdini that allow particles to be confined to a mesh and flow within it?
