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 of the machine doing the rendering. This provides two benefits that can be significant:
- Faster access to the textures during the rendering, especially if the local drive is an SSD.
- Saving network bandwidth, which can become clogged when several computers rendering simultaneously are accessing textures simultaneously while rendering.
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.
