bool Solid{ get set }


A flag that indicates the Mesh for this node will be used in ray intersection tests. This flag is ignored if no Mesh is attached.


Collision Tagged Nodes

One particularly practical example of tagging your ModelNode names would be to set up collision information for your Model. If, for example, you have a low resolution mesh designed specifically for fast collision detection, you can tag your non-solid nodes as “[Intangible]”, and your collider nodes as “[Invisible]”:

foreach (ModelNode node in model.Nodes)
	node.Solid   = node.Name.Contains("[Intangible]") == false;
	node.Visible = node.Name.Contains("[Invisible]")  == false;
