When enabled, rendering occurs on the Local GPU specified, if available, rather than the CPU. The output between the GPU and CPU is identical on NVIDIA GPUs, but using the GPU can significantly improve processing performance.

CaraVR supports AMD GPUs on late 2013 Mac Pro 6,1, mid 2015 Mac Pro 11,5, and and late 2016 MacBook Pro 13,3, running OS X 10.9.3 'Mavericks', or later. While, in some cases the bit-wise equality between GPU and CPU holds, for some operations there are limitations to the accuracy possible with this configuration.

Note:  Enabling this option with no local GPU allows the script to run on the GPU whenever the script is opened on a machine that does have a GPU available.
You should also select this if you wish to render from the command line with the --gpu option.

GPU processing also requires certain NVIDIA and AMD drivers. For more information on the minimum requirements, please refer to the Nuke Release Notes available in Help > Release Notes.

When enabled, use SIMD instructions on the CPU where possible.

Sets the view to use for the left eye when calculating depth.

Sets the view to use for the right eye when calculating depth.

Determines how far apart the two views are, from a viewer's perspective. If you set the Eye Separation, or interpupillary distance (IPD), too low, objects in the scene appear crushed horizontally, but raising it too high can leave holes in the stitch.

The IPD is measured in the same units as the Rig Size control in the upstream C_CameraSolver properties, so adjust it accordingly.

When enabled, use ZInv depth encoding to reverse the way depth is represented in the image, providing smoother depth maps. The inversion treats smaller values in the image as greater depth, rather than the default where small values equal less depth.

When Z Inverse is enabled, sets the minimum distance for depth encoding.

When Z Inverse is disabled, this control has no effect.
