This compound orients particles in the direction of the surface 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 Surface Normals.

Output Ports: Execute
|
Surface1 |
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. |
|
Enable Cutoff Distance |
Toggles the activeness of the Cutoff Distance option. |
|
Cutoff Distance |
The maximum distance (in Softimage units) within which the particles are aligned to the object. |
|
Weight |
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. |
|
Select Alignment Type |
The way in which the particles are aligned: Full Alignment or Align Local Vector to Surface Normal. |
|
Local Vector |
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 your particle type to cone, you can see that the Y axis is the direction of the cone point. The X and Y axes are the sideways axes. |
