ModelNode

from panda3d.core import ModelNode
class ModelNode

Bases: PandaNode

This node is placed at key points within the scene graph to indicate the roots of “models”: subtrees that are conceptually to be treated as a single unit, like a car or a room, for instance. It doesn’t affect rendering or any other operations; it’s primarily useful as a high-level model indication.

ModelNodes are created in response to a <Model> { 1 } flag within an egg file.
