Sometimes you’ll see an ICE tree in italics in the explorer.

The italics mean that the ICE tree is not owned by the object, but by another object. By “not owned”, I mean that the ICE tree is not plugged into an execute port on an ICETree node in the stack of the object. In this case, the italicized ICETree is not owned by Growing_Strands_PointCloud, but by polymsh.

Roughly speaking, the italics mean “this ICE tree isn’t defined here, but it does use this object”.

Note that you can drag this shared ICE tree to another location in the stack.
