Shape operators control the geometry of particles.
Topics in this section
Shape Operator
The new Shape operator, which replaces the original version, expands the choices of ready-made geometry for use in the particle system. You can specify particles in a number of different predefined 2D and 3D shapes, such as geometric primitives, alphanumeric characters, and musical notes, as well as particle size and scale.
Shape Facing Operator
The Shape Facing operator creates each particle as a rectangle that always faces a particular object, camera, or direction. For effects like smoke, fire, water, bubbles, or snowflakes, use Shape Facing with a material containing appropriate opacity and diffuse maps.
Shape Mark Operator
Use the Shape Mark operator to replace each particle with either a rectangle or a box cut out from the particle geometry with an image mapped onto it. The image can be animated and the animation can be synchronized with particle events.
