ICE does not support hair or legacy non-ICE particle clouds. It also does not support groups or branches.
ICE is the Interactive Creative Environment. It is a visual programming system for procedurally controlling simulations and deformations.
• You can completely control particle systems. You can add and remove points on point clouds. You can move points directly, or apply a simulation using particle or rigid body behavior.
• You can deform various geometry types, including polygon meshes, NURBS surfaces, curves, lattices, and point clouds. However, you cannot add or remove components on any geometry type except point clouds.
You create effects by connecting nodes in a graph or tree. ICE trees can read and write almost any attribute, including properties on objects in the scene. You can even define new attributes and use them in any way you want.

This section describes the overall workflow for manually creating an ICE tree on an object.
• If you want to create a particle simulation emitted from an object, see Creating ICE Particle Emissions instead.
• If desired, you can start with a point cloud from the Get > Primitive > Point Cloud menu.
Creating an ICE Tree
1. Display the ICE tree view. See The ICE Tree View.
2. Select the geometric object to which you want to apply an ICE tree.
If the ICE Tree view is locked, you must update it to show the selection.
3. Create an ICE tree or a simulated ICE tree.
Whether the tree is simulated or not determines where it is located in the construction stack. See Understanding the ICE Framework.
4. Add nodes and connect them to achieve the effect you want. See the following sections:
5. If the tree is a simulation, add the appropriate node to make sure that it updates properly at each frame: Simulate Particles or Simulate Rigid Bodies.
6. If desired, you can create a compound node and export it for reuse in other trees and scenes. See Building ICE Compounds.
Editing an Existing ICE Tree
1. Select the object with an ICE tree.
2. If necessary, click Refresh in the ICE Tree view.
3. If there are multiple trees on the object, select the appropriate tree node in the explorer on the right of the view. If the explorer is not visible, click Hide/Show Explorer View (the right arrow button).
