The Octane plugin exists within the Cinema 4D infrastructure and uses the C4D SDK to operate. As a result, the plugin is heavily dependent upon internal processing done by Cinema. As it turns out, Cinema can change internal IDs for a variety of things on the fly (for whatever purpose), making these IDs hard to manage within the plugin, and causing instability from time to time. Using Octane's tags minimizes this situation, as the tags allow Octane to accurately track these items and conditions. The necessary IDs are maintained, enabling internal stability inside of Octane and act as a shield from Cinema 4D when these IDs change in the C4D engine.
