I've tried the PTC, I've tried putting GLB files in my _CustomHomes folder, I even see the examples of a cafe and a theater in the folder but can't seem to access them anywhere in Oculus Home. When I go to create a new Home, it just gives me the same default option as always. What gives? Is this feature actually implemented yet or is Oculus just saying it is?
I just tried, it's working fine for me. I made a simple scene in Blender 2.80 (flat plane, a cube and a sphere) and exported to a glb file in C:\Users\kojack\Documents\Oculus Home\_Import\_CustomHomes
In the home menu I selected Places / Templates and the glb was there. I selected it, uploaded and created a home.
Now I have a very boring looking white plane with a box and sphere as my home. 🙂
