MdlEntitySnapshot

class omni.mdl.neuraylib.MdlEntitySnapshot

Bases: pybind11_object

MDL representation of a shade node along with the currently set parameters. Parameters can be inspected while changes are reflected from USD (in rtx.hydra.plugin). This snapshot is passed to the ISceneRenderer for creating and updating the renderer material.

When the MdlEntity changed (different module or function name), a new snapshot can be created while to old one still exist but might not be valid anymore (in case of reloads).
