Yesterday I wrote about Microsoft’s documentation on creating custom spaces for Windows Mixed Reality. Having spent some time playing with the tools I found you can easily create your own space and import it into Windows Mixed Reality.

All you need is Paint 3D on a PC running the Windows 10 April 2018 update.

The first step is to open up Paint 3D and import a 3D object as your main space, I imported a stadium from the samples in Paint 3D to get started (you can create your own if you like).

With your object in Paint 3D you can add text, import extra objects and add stickers. The stickers can be from Microsoft’s gallery or your own pictures from your PC. So play around with the app create your design.

The next stage is to save your design as a GLB file. Go to File and Sales Save as Copy using the GLB format.

In theory that should be the entire object editing you need to do but I found my models where tiny so I need to adjust the scale. Using 3D Builder you can change the size.

To edit the file, navigate to the folder where you saved the GLB file, right click on it and select Open with 3D Builder. Click on the tick box to import the object and then click on your design object to select it.

Click on the Scale button and then click on the measurement value. For my stadium, I changed it from 10mm (tiny) to 70000mm (big) which is big enough to walk around in WMR.

Now save the object with Save As and select GLB as the format.

The final step is to move the GLB file to %LOCALAPPDATA%\Packages\EnvironmentsApp_cw5n1h2txyewy\LocalState

With the file in the folder you can now fire up Windows Mixed Reality, click on the Places button and select the name of your GLB file. Windows Mixed Reality should then take you to your custom environment where you can add objects, app and walk around just as you can with the Cliff House and Skyloft
