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 texture 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.

By default, the Network Cache in not active. We recommend you turn it on. You only need to specify its maximum size (we recommend at least 50GB). The only inconvenience is an initial delay before you start to see the image on the first render (because the first time the cache needs to be filled). The amount of delay will depend on how many textures are used in that particular image. Note that if you use only one computer, and all the texture data are on a local drive of that computer, enabling Use Network Cache won't have any effect.
