The Mesh operator can be used to enable particle mesh rendering.
If you wish to render particles within an event, you must add a Mesh operator to the event.
Vertex Clouds can be rendered by point renderers like Thinkbox’s Krakatoa, or converted to isosurfaces using meshing plugins like Thinkbox’s Frost.
Triangle Mesh: particle shape meshes will be combined into a single editable mesh.
VRay Instances: particle shape meshes will be converted into VRay-compatible instances.
Render Only: controls whether the meshing operation will only happen during rendering.
