What are the benefits of getting all this software in one collection?

In addition to providing a great price value, the Media & Entertainment Collection provides the essential 3D, rendering, and simulation tools you need. With your subscription, you can create VFX and animated 3D content, render with Arnold, and create simulations using the entitlements to the Bifrost engine. Because the collection provides both the latest and previous versions of included products, it also supports compatibility with others on your team. And, you manage only one collection license rather than multiple product licenses.
