Prepare a new Unity3D project to deploy to HoloLens.

Do you want to deploy your Unity3D project to the HoloLens? What are the minimum steps you need to take before creating a build? This tutorial shows how to create (and deploy) a 3D app for your HoloLens.

• Start a new Unity project

• Press CTRL-S to save the scene

• Click CTRL-SHIFT-B to open the Build Settings window
• Click Add Open Scenes
• Select Universal Windows Platform
• Click Switch Platform

• Notice the warning Currently selected scripting backend (IL2CPP) is not installed. That is because I only installed .NET support. We fix this problem in the player settings:

• Click Player Settings
• Find the Other Settings section and set Scripting Backend to .NET

• Go to the Publish Settings > Capabilities section and check SpatialPerception (This and the next step allows the app to run in 3D mode, instead of being projected at the wall)

• Go to the XR Settings section and check Virtual Reality Supported

• Go back to the Build Settings window and check Unity C# Projects
• Click Build

• Create folder build
• Click Select

The build now starts and can be opened in Visual Studio for deployment to the HoloLens.

Deploying to HoloLens (optional)

• Open the build folder
• Open the generated solution in Visual Studio
• Restore NuGet packages

• Switch the solution platform to x86
• Click the little arrow next to Local Machine or Remote machine
• Select Remote machine
• Enter IP Address
• Click Select

• Press CTRL-F5 to deploy to the HoloLens
