Proximal
Proximal is a shader that is based on distance dependencies. The shader outputs a luminance value
based on how far away the surface being shaded is from a specied object (you can choose whether
the object origin, points, edges or polygon center should be used). Proximal works best in the
Luminance channel.
Proximal also works with particles (with CINEMA 4D particles and with Thinking Particles). A luminance
effect will be generated each time a particle hits the surface (see the example above).
Objects
Drag the names of the object or objects that will be used to calculate Proximal from the Object
manager into this box. In the case of particles, drag the Emitter (CINEMA 4D particles) or Particle
Geometry object (Thinking Particles) into the Objects box.
Exclude Parent
If Include Sub-objects is enabled and Exclude Parent is checked then the parent object is disregarded
in the Proximal calculations.
Include Sub-objects
If enabled, the children of the found object will be included in the proximal calculations.
Use Vertices
Allows the user to specify that the sampling points for the Proximal shader to use are dened by the
vertices of the named polygon object. This allows for effects such as one object passing through
another object. The object must be a polygon object.
