Running Metahumans on the Hololens 2 reliably was a little more complicated than I thought it would be, but once you get the hang of the method it’s pretty easy.<\/p>\n

We’ll be running the program, in our case Affinity on our PCs and using the Hololens Holographic Remoting app to stream Affinity to the headset. Because this is a multiplayer experience, 2 PCs and 2 headsets<\/strong> will be required. One will be the host\/therapist who does all the controlling, and one will be the client\/patient whose gaze we will be tracking.  So the first thing you need to do if work out all the IP addresses of both your PCs and headsets.<\/p>\n

STEP 1 : Find out the IP of your PC <\/h2>\n

To find out the IP of your pcs, open up a command prompt or terminal by clicking on the windows icon and typing “command”<\/p>\n

\"\"<\/p>\n

 <\/p>\n

In the command prompt type in ipconfig <\/strong>and hit enter<\/strong><\/p>\n

\"\"<\/p>\n

 <\/p>\n

The number you want to take note of is the IPv4 Address<\/strong><\/p>\n

\"\"<\/p>\n

 <\/p>\n

STEP 2 : Find out the IP of your Hololens 2 Headsets<\/h2>\n

You’ll need to start up your headsets for this.  Find the Holographic Remoting app.<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

 <\/p>\n

The number you need is the one in yellow<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Okay now that you have all your numbers set, you’re ready to fire up the app!<\/p>\n

 <\/p>\n

STEP 3: Start the App as the Host\/Therapist<\/h2>\n

So you have your headset on with the Holographic Remoting Player waiting for a connection. Next you need to go back to your command prompt\/terminal and start up the app for streaming. So CD<\/strong> into the WindowsNoEditor<\/strong> folder where you have Affinity.exe<\/strong> <\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Now you need to stand in position because the app will load and orient itself around you. Here is how the main scene is set up. You will need to be standing where the white dot is, so that the Metahuman can load in, 2 meters directly in front of you. <\/p>\n

Once you have loaded the scene, the second player\/patient will need to stand in exactly the same place to load up their app and join your session. This way you will both be oriented in the app correctly. <\/p>\n

It’s probably a good idea to put a marker on the ground so that you both know where to stand as it loads up.<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Once you are standing in position, have an assistant run the following command in the command prompt<\/p>\n

Affinity.exe -vr -HololensRemoting=your-headset-ip<\/em><\/span><\/pre>\n
NOTE: if the app is not orienting the way you would expect, it is a good idea to remove all holograms to clear the headset and make it remove all markers.<\/p>\n
This is what you will see as it loads up. On the intro control panel, you will select “HOST” because you will be controlling the session.<\/p>\n
