This **Node** can be used to retrieve a single ground **attribute** for the particle emitter. The information that this node returns is retrieved using a projection of the **emitter** (not the particles themselves) onto the ground from it's current position. Essentially a ray is cast from the emitter to the center of the world, and the information retrieved from the point of intersection between this ray and the terrain beneath it.

    | `Position` | Vec3 | Returns the position *on the ground* for the emitter of the particle as a Vec3 with the format (x, y, z). This position is relative to the emitter position. |
    | `Colour`   | Vec4 | Returns the color of the ground at the relative particle emitter position as a vec4 corresponding to the (R, G, B, A) values of the terrain texture.         |
