Description
-----------

ParticlesMaterial defines particle properties and behavior. It is used in the ``process_material`` of :ref:`Particles<class_particles>` and :ref:`Particles2D<class_particles2d>` emitter nodes.

Some of this material's properties are applied to each particle when emitted, while others can have a :ref:`CurveTexture<class_curvetexture>` applied to vary values over the lifetime of the particle.
