1. Save start-up time for renders.
2. Save local hard drive space as 3Delight will convert textures into a temporary local folder.
3. The automatic color space conversion for Katana is not satisfactory and a more fine tuned approach is needed.
4. You want to pass additional options to tdlmake (e.g. filtering or output data type).

The Network Cache

3Delight has a unique feature that improves performance when rendering over networked environments: the renderer can cache textures that are located on the network to the local drive for faster data access and saving network bandwidth. The network cache content is updated automatically: when files are modified on the file server, the local (cached) copies will be automatically updated the first time they are needed for a rendering. If there is no more space in the cache,  copied textures are removed to make space for incoming textures by following the Least Recently Used (LRU) principle.
