Hello there, to run this , you will need to install pip for blender https://blender.stackexchange.com/questions/56011/how-to-use-pip-with-blenders-bundled-python you will also need a windows machine as openvr python is glued to this operating system -as is Oculus . If you need a temporary headset for testing, you can use a usb streamer like this: https://gizmodo.com/notculus-rift-how-i-hacked-together-my-own-serious-vr-1688354373?fbclid=IwAR2Ui1WTChupy8ATfz3ceK0rqV14EU4AKkI3AyR2npOaP9lvNSozcGyzjZs The only caviat on mine is that the micro usb cable keeps popping out and I have to keep it still. This might not be an issue for usb-c.

Note on admin rights

if you are on windows and it says there is no permissions, run cmd, git bash, powershell, or whatever shell you are using as administrator. You can also set permissions on the root Blender Foundation folder to allow read/write. Otherwise, copy Blender to a folder where you do have permissions. Next you wil need to install the requirements

pip install -r requirements.txt

or pip install pyzmq openvr

Start the server

to start the server using blender python (or python with pyzmq installed):

python zeroserver.py 5556

This listens for incoming connections on port 5556 and sends them on that socket.

Load the blender file

blender blend/blvrpy.blend

Open the blvr.py:

Blender Text Editor

File

Open

open py/blender/blvr.py

click Run Script (or alt+ p)

Results

if all goes well you should see a camera with location being modified across a socket. This means that technically anything could be used as input for blender now, I have the server sending JSON and it is currently setup to read /set any property of the object. the format is this : <object.name>"."<object.key> = <value>

{
   "name":"bpy.data.objects['Camera']",
   "location":"(0,1,2)" 

}

would execute as:

bpy.data.object["Camera"].location = (0,1,2)

Troubleshooting

If your blender freezes, go to the console and hit ctrl+c to stop the script. It will freeze if the server is not running.
