VisualMaterialOverrideTrait

trait VisualMaterialOverrideTrait:
    .doc: """
Apply this trait to a visual node to override visual materials in that node and its subnodes.
Material parameter on geometries will not be changed, but it will not be used in simulation
either. To keep a set material on a geometry, add it to the material_override_nodes_excluded
list.

Note that when the owning node has this trait, any changes to materials in a non-excluded
node will not have any effect. Also, an override will never override another override. This
means that if you have a node with this trait and a subnode in it also has this trait, the
geometries in the subnode will keep the material set by the override trait in that subnode.

material_override - this material will override geometry materials in the node
material_override_nodes_excluded - list of nodes that will keep their original material
