This compound aligns particles to a position in global space. You can use this compound to do “billboard” effects by aligning the particles to point to the global position of a camera root.
Plug this compound's Execute output into a Port on the ICETree node.
For more information, see Aligning Particles to a Position (Billboarding).

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. |
|
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. |
|
Global Pos |
The XYZ position in global space to which the particles are aligned. You can plug in the global position of a camera to have the particles aligned toward it in order to create “billboard” effects. Create a Get Data node for the camera's, then open its property editor and enter .kine.global.pos after the camera's name in the text box. Plug the camera's Value output into this port. |
