If the condition is True, then do nothing. Given a truthy condition, if the condition is False then raise anĪssertionError. For instance, type conflicts may occur during the registration of a python state or python handle. Raised if a type conflict occurs during an operation. Raised if you try to unregister a Python state that was never registered. Generic catch-all exception for various errors in Houdini that don’t have their own dedicated exception classes. Raised when you try to access a reference to an object that has since been deleted. Raised when you try to call an API function/method that is not available. Raise this exception in a Python node to signal that the node has a warning. Raise this exception in a Python node to signal that the node is in error. Raised when you pass a sequence of the wrong length to a function.Įxception class for when loading a hip file in Houdini generates warnings.Įxception raised when a name conflict is detected during an operation. Raised if you try to call a method on a Node that doesn’t support it. Raised if you try to set a node’s input to something invalid. Raised if you try to use a custom handle that is not registered with the system.Įxception raised when you try to access a reference to SOP Geometry that has since failed to cook. Raised if you try to modify SOP geometry from outside of a Python SOP. Matches the incoming and outgoing values and slopes.īase class for all exceptions in the hou module.
