Installation on Linux

CaraVR is distributed as a software download from our website. To install CaraVR 2.0 on a computer running Linux, follow these instructions:

Note: Throughout the following instructions, replace <version> with the Nuke release you're using.

Download the following file from our website at www.foundry.com/products/cara-vr:

CaraVR_2.0v2_Nuke_<version>-linux-x86-release-64.tgz

Move the downloaded file to the following directory (create the directory if it does not yet exist):

/usr/local/Nuke/

Note: You may need root or sudo permissions to make changes to /usr/local/ directories.

In the above directory, extract the files from the archive using the following command.

tar xvzf CaraVR_2.0v2_Nuke_<version>-linux-x86-release-64.tgz

This will create the <nuke_version>/plugins/CaraVR/<caravr_version> sub-directory (if it doesn’t already exist), and install CaraVR in that directory.

Proceed to Licensing.

Installing Oculus Rift and HTC Vive

Linux support for Oculus Rift DK2 and HTC Vive requires the OpenHMD third-party library, which is installed as part of the CaraVR toolset.

Support for the Oculus Rift CV1 is also included, but there are some additional installation steps required:

Warning: Do not plug the CV1 headset in or start Nuke before performing these steps.

Ensure there are no legacy Oculus drivers installed. If there are, uninstall them.

Make sure your user ID belongs to the group plugdev. Review your Linux distribution's documentation for information on how to add user IDs to groups.

As root, create a udev system rule using the following commands, supplied by OpenHMD:

echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="2833", MODE="0666", GROUP="plugdev"' > /etc/udev/rules.d/83-hmd.rules

udevadm control --reload-rules

This rule allows user IDs belonging to the plugdev group access to the Oculus device.

Restart your machine.

Plug in the CV1 headset and start Nuke.

Note: If you're using the CV1 headset on Linux, be aware that:

Unlike the Oculus DK2, the CV1 displays black until you turn it on inside Nuke's Viewer settings.

The CV1 does not appear in the list of available screens in Gnome/Kde, it is displayed with the supported devices in Monitor Output.

When you initially turn on Monitor Output, all available monitors display black for a few seconds as the OS adjusts to the new configuration.

The CV1 remains on until you close Nuke, which causes all available monitors to display black for a few seconds as the OS adjusts to the new configuration.

See Reviewing Your Work for more information on using headsets.
