Chapter 2 Major Features and New Nodes 43
From that point on, Shake references the cached image data within that node, instead
of constantly reprocessing the nodes that precede it, unless a change is made to one of
the preceding nodes.
Important: Using a Cache node crops the image to the current image size, eliminating
data from the Infinite Workspace from that point in the node tree on.
When the Cache Becomes Full
Cache nodes that can’t be cached appear red in the Node View.
There are two possible situations when a Cache node won’t be able to actually cache:
The input image size is larger than the maximum allowable cache file size.
You can easily tell if this is the case by opening the indicated Cache node into the
Parameters tab, then checking to see if the value of the imageSize (an input image’s Bit-
depth * its Width * its Height) is larger than the value of the imageSizeLimit. If this is
the case, you need to either increase the value assigned to the
diskCache.cacheMaxFileSize global plug, or change the size of the incoming image.
This section of the node
tree is cached by the
selected Cache node
below.
This Cache node caches
the image generated by
the nodes above it.
This node is able to cache. This node is unable to cache.
