A visual shader node that makes particles emitted in a shape defined by a [Mesh]. [VisualShaderNodeParticleEmitter] that makes the particles emitted in a shape of the assigned [member mesh]. It will emit from the mesh's surfaces, either all or only the specified one. The [Mesh] that defines emission shape. Index of the surface that emits particles. [member use_all_surfaces] must be [code]false[/code] for this to take effect. If [code]true[/code], the particles will emit from all surfaces of the mesh.
