Mograph: particles, proximity

This is part of a complete set of of explanations for each mograph basic functions.

There is an invisible plane. Its points set the positions of the cube clones (mograph cloner object set to "object". A cube primitive as a child object).

The plane was set to invisible in the basic tab of the attributes manager. Also render visibility is set to "invisible".

The plane has a material assigned with the proximity shader in the color channel. The proximity shader reacts to the particles.
The shader effector needs the planes material tag.
In the shader effectors "parameter" tab (attributes manager), the Z-size set to higher than "1" makes the shader effector change the Z-size of the cubes where the particles get close to the plane.

If you want the scene file to understand this better, send me a note and I´ll send you a rapidshare link (ca. 20 MB).
