A Renderable object is a type of node on the client that has some sort of visual representation in the client display.
Examples of renderable objects are:
- Particle effects
- Action marks
- Bone trackers
- Path followers
- Pathfinding nodes
- Physics groups, which can have debug rendering turned on
- Physics joints
Some of these objects may not "render" normally, but will have some renderable aspect in debug mode and share the same category of behavior.
