It is used in the [code]process_material[/code] of [GPUParticles3D] and [GPUParticles2D] emitter nodes. Some of this material's properties are applied to each particle when emitted, while others can have a [CurveTexture] applied to vary values over the lifetime of the particle. - When a randomness ratio is applied to a property it is used to scale that property by a random amount. The random ratio is used to interpolate between [code]1.0[/code] and a random number less than one, the result is multiplied by the property to obtain the randomized property. For example a random ratio of [code]0.4[/code] would scale the original property between [code]0.4-1.0[/code] of its original value. + Particle animation is available only in [GPUParticles2D].
