This compound orients particles in the direction of a vector that you choose. This is useful for setting up anything that needs a specific orientation relative to another scene element, such as the surface normals of an object.
Plug this compound's Execute output into a Port on the ICETree node.

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. |
|
To Vector |
The vector to which the particle axis you've chosen (Local Vector) is aligned. This could be something like the surface normal of an 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. |
