Particle velocity and rotation will be set by sampling this texture at the same point as the [member emission_point_texture]. Used only in [constant EMISSION_SHAPE_DIRECTED_POINTS]. Can be created automatically from mesh or node by selecting "Create Emission Points from Mesh/Node" under the "Particles" tool in the toolbar.
