Tutorial Python Node: Attributes With Simple Data

This is a tutorial node. It creates both an input and output attribute of every simple supported data type. The values are modified in a simple way so that the compute modifies values. It is the same as node omni.graph.tutorials.SimpleData, except it is implemented in Python instead of C++.

Installation

To use this node enable omni.graph.tutorials in the Extension Manager.
