This compound orients particles in the direction of the normals of an object. This is useful for setting up anything that
needs a specific orientation along an object, such as bugs crawling on a rock or something sliding over a surface.
Plug this compound's Execute output into a Port on the ICETree node.
For more information, see Aligning Particles to a Surface [ICE Particle Simulations].
Tasks: Particles/Orientation, Particles/Surface Interaction
Output Ports: Execute
|
The object to which that you want the particles aligned. This must be an object with a surface. Plug in the object's Value
output into this port.

|
Toggles the activeness of the Cutoff Distance option.
|
|
The maximum distance (in Softimage units) within which the particles are aligned to the object.
|
|
Defines how much the particle is rotated each frame. The value is a ratio, so if you set it to 1.0, the particle is immediately
aligned. If you set this value to 0.1, the particle rotates by 10% each frame.

The way in which the particles are aligned:
|
|
The vector that is used to align the particles. The Y axis is typically the vector that points along the length of a particle.
If you change the particle shape to a cone, you can see that the Y axis is the direction of the cone point. The X and Y axes
are the sideways axes.
