DR Tab

Enable – Enables additional parameters and settings needed to distribute the rendering across additional computers.

Use Local Machine – When enabled, the client/local machine functions as a render server along with the other computers used to complete the rendering task. When disabled, all rendering is done on other machines apart of the DR set up.

Transfer Missing Assets – Allows render servers to automatically download missing rendering assets from the client machine, including textures, V-Ray proxy files, IES profiles, GI solution caches (irradiance maps, light caches), etc.

Use Cached Assets On DR – Tells the render servers to keep the downloaded rendering assets between different DR sessions. If disabled, the render assets are automatically deleted once the render server disconnects from the client machine at the end of the rendering. When enabled, assets are kept in a folder on disk.

Cache Limit Type – Allows you to specify under what conditions the assets cache is cleaned up. The possible values are:

None – Assets are never deleted from the render servers' cache.
Age (Hours) – Assets are kept for the specified amount of time. At the end of the rendering, the render servers delete assets that have been transferred before the specified time limit.
Size (GB) – When the size of the assets on a render server exceeds the specified amount, least recently used assets are automatically deleted at the end of each render until the folder size is less than the limit.

Cache Limit Value – The specific value of the limit for the asset cache. This is either hours or GB, depending on the value of Cache Limit Type.

Overwrite Local Cache Settings – (available when Transfer Missing Assets and Use Cached Assets on DR are enabled) When enabled, the render nodes ignore their local settings for how long they'll keep a transferred asset if any such settings have been placed. Instead, the nodes use the settings from the host's Houdini render settings.

Default Port – Specifies the default port number at which the DR server operates. The default value is 20207.

Number of Hosts – Specifies the number of hosts to use for DR. This value controls the number of host input fields below.
