Overview
| Option | Description |
|---|---|
| Use all processor cores __________________________ | The rendering process will attempt to use all the processor cores of the computer. This is the default. |
| Use all processor cores but one | The rendering process will attempt to use all processor cores, but one. For example, on a computer that has two quad-core CPUs, only 7 cores will be used. |
| Use custom number of threads | Specifies to use a custom number of threads for rendering. This number must specified by the Number of Threads attributes. |
Number of Threads
This attributes is only available when Multi-Threading is set to Use custom number of threads. Using a positive value, it specifies the exact number of threads that will be launched by the rendering process. Using a negative value instead, it specifies to use as many processor cores as there are available, but leave the specified number of cores for other tasks. For example, on a 6-core computer, using a value of -2 will have the rendering process use 4 cores.
Texture Cache Size
This attribute specify the size of the texture cache held in memory by 3Delight for quick temporary access. The cache size is expressed in megabytes. Raise this value if a lot of textures are used and you have a lot of RAM to spare. In most cases, we would not recommend to raise it to more than 25% of the size of physical RAM. Generally, the default cache size of 128MB is enough. Please note that this cache is in RAM and is completely different than the Network Cache, which is on disk (see below).
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 hard 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 automatically be updated the first time they are needed for a rendering.
Use Network Cache
A toggle enabling or disabling the network cache. By default, this toggle is off.
Network Cache Directory
Specifies the directory in which files will be cached. This directory should be local to the machine that performs the render (on the system drive for instance). By default, this attribute is set to <default>, which is: /var/tmp/3DelightCache on Mac OS X and on Linux, and %TEMP%\3DelightCache on Windows (which typically translates to C:\Users\User Name\AppData\Local\Temp(%USERPROFILE%\AppData\Local\Temp\3DelightCache).
Network Cache Size
Specifies the maximum size of the cache, in gigabytes. The default size is 15 gigabytes. Refer to 3Delight User's Manual for a more technical discussion on how the cache is managed.
