 This is useful to fix some specific renderer glitches and advanced hacking of Maya Scene files. `Patch name` is label for patch for easier orientation.
 `Patch regex` is regex used to find line in file, after `Patch line` string is inserted. Note that you need to add line ending.
 
+### Extract GPU Cache
+
+![Maya GPU Cache](assets/maya-admin_gpu_cache.png)
+
+- **Step** Specifies how often samples are taken during file creation. By default, one sample of your object's transformations is taken every frame and saved to the Alembic file.
+
+  For example, a value of 2 caches the transformations of the current object at every other frame of the Cache Time Range.
+
+- **Step Save** Specifies which samples are saved during cache creation. For example, a value of 2 specifies that only every other sample specified by the Step # frame(s) option is saved to your Alembic file.
+
+- **Optimize Hierarchy** When on, nodes and objects in a selected hierarchy are consolidated to maximize the performance of the cache file during playback.
+- **Optimization Threshold** (Available only when Optimize Hierarchy is on.) Specifies the maximum number of vertices contained in a single draw primitive. The default value of 40000 may be ideal for most Maya supported graphics cards. When set to the default value, after optimization, each object in the GPU cache file(s) will have no more than 40000 vertices. This value can be set higher depending on the memory available on your system graphics card.
+
+- **Optimize Animations for Motion Blur** When on, objects with animated transform nodes display with motion blur when the cache is played back in Viewport 2.0 render mode. See Viewport 2.0 options.
+
+  Maya first determines if the GPU cache includes animation data. If the GPU cache is static and does not contain animation data, Maya does not optimize the GPU cache for motion blur.
+
+:::note Motion Blur does not support Cached Playback.
+:::
+
+- **Write Materials** When on, Maya exports the Lambert and Phong materials from source geometry to the GPU Cache file. These materials display when the GPU-cached file is played back in Viewport 2.0.
+
+  GPU-cached objects support all the high-quality lighting and shading effects provide by the Viewport 2.0 rendering mode. See Viewport 2.0 options.
+
+:::note Lambert and Phong materials do not display on GPU-cached files when they are played back in scene view's High Quality Rendering or Default Quality Rendering modes.
+:::
+
+- **Use Base Tessellation** Exports geometry with base tessellation and no smoothing applied. If this setting is turned off, the extractor will export geometry with the current Smooth Mesh Preview setting applied.

 ### Extract Playblast Settings (review)
 These settings provide granular control over how the playblasts or reviews are produced in Maya.
