=======================
**Inherits:** :ref:`Material<class_Material>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
Particle properties for :ref:`GPUParticles3D<class_GPUParticles3D>` and :ref:`GPUParticles2D<class_GPUParticles2D>` nodes.

Description
-----------
ParticleProcessMaterial defines particle properties and behavior. It is used in the ``process_material`` of :ref:`GPUParticles3D<class_GPUParticles3D>` and :ref:`GPUParticles2D<class_GPUParticles2D>` 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.
Particle animation is available only in :ref:`GPUParticles2D<class_GPUParticles2D>`. To use it, attach a :ref:`CanvasItemMaterial<class_CanvasItemMaterial>`, with :ref:`CanvasItemMaterial.particles_animation<class_CanvasItemMaterial_property_particles_animation>` enabled, to the particles node.

This value controls the overall scale/frequency of the turbulence noise pattern.
A small scale will result in smaller features with more detail while a high scale will result in smoother noise with larger features.
