Obtaining a License Key
Activating a License Key
The Troubleshooting page explains how to resolve common licensing issues.
3Delight licenses are related to threads or processes and are bound to a machine. So a quad-core license offers the following unique flexibility on a given machine: Using an unlimited multi-core license offers the same king of flexibility but with no limitation on how many threads or separate processes that can be launched. For an example, on a single 8 cores machine one can: All these scenarios are independent on how many CPUs are available on the given machine. In practice, to fully use a dual-CPU / dual-core machine, one need a quad-core license. Also as a practical note for the unlimited multi-core license, even if running more threads than the number of available cores can sometime provide a small incremental gain in performance, there is a limit to the gain one can achieve this way. As a reminder, all licenses are floating; they can be used by any machine in a network. They are also platform independent. When running non-free 3Delight without a license, for testing purposes, a watermark will be displayed. In this form, the renderer cannot be used for commercial work.How 3Delight Licensing Works
