This shader provides you with the density of the particles.
This way you get particle support for the volume shaders
The shader reads the particle data and outputs density and color of the particles. You can use it in two different ways:
* A) As shader for the particle volume object:
Apply it as input of the Volume Shader, then you can render the particles.
* B) As a texture inside the shader tree of a different object.
You can mix textures based on the distance to particles. e.g. to create a wet texture.
