|
Particle properties for [Particles] and [Particles2D] nodes.
|
|
</brief_description>
|
|
<description>
|
|
ParticlesMaterial defines particle properties and behavior. It is used in the [code]process_material[/code] of [Particles] and [Particles2D] 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.
