This page provides information about the Particle Sampler texture in V-Ray for Cinema 4D.
Overview
The Particle Sampler Texture reads the attributes of the particle system, such as the particles' color, age, velocity, etc, and outputs the data to a material that can be assigned to the V-Ray Particles Geometry that shades the particles. This allows per-particle shading and/or adjustments.
The Particle Sampler texture can also sample any object's Color parameter (found in the Basic rollout) and output it to shade something else or the object itself, even though it is not a particle system.

General
Default Color – Assigns the default color, which is rendered if the Default Output type is selected.
Texture – Allows a texture file to be applied. Use the Mix Strength parameter to blend between the Texture and the Default Color.
Output – Defines which channel from the particle system is used to derive data. The texture takes the value as is, i.e., if the value is a number or a color, it can only be connected to an Output type of the same kind. The texture applies the value to the material slot it is assigned to.
Default – This option applies the Default Color when there is no color information available from the linked particles.
Color – Takes the color of the particles and applies it to the texture.
Acceleration – Takes the particles' acceleration value and applies it to the texture.
Velocity – Takes the value of the particles' velocity(speed) value and outputs it through the texture.
Age – Takes the particles' age value and outputs it through the texture.
Lifespan – Takes the value of the particles' lifespan attribute and outputs it through the texture.
The Phoenix Particle Type does not currently support the VRayParticleSampler texture. Normally, the texture would need to be attached as the Color Source of the particles.
