Start Thread on
Specifies how many threads to start. By default 3Delight for Softimage will start as many threads as there are available cores.
Maximum Reflections/Refractions Depth
The limit ray depth until which reflection and refraction rays are traced. After this depth, only HDRI maps is sampled.
Enable Network Caching
From 3Delight Users Manual:
"3Delight offers a special extension for more efficient rendering in networked environments: a local file cache for textures and archives to minimize network traffic and file server load. This proves particularly powerful when using a large quantity of rendering servers.
The working principle of 3Delight’s network cache is to copy files to a local file system and reuse them when needed. If either a texture or a RIB archive is cacheable and the file cache is full, one or more files are removed from the cache to make space for the new one; a LRU (Least Recently Used) strategy is used to choose which texture(s) or archive(s) to remove from the cache."
Local Network Cache Directory
The directory, on each rendering machine, where the textures and RIB files will be cached.
Cache Size
The total cache size in megabytes.
Cache Network Writes
Enables network write caching: instead of writing data over the network in small bursts, 3Delight will write images locally and then transfer them efficiently at the end of each render. This feature can have a very significant impact on large render farms.
