After you export the world, how do you map the 6 textures to a sphere in Unity? Is there a Unity project that is set up to accept these textures? Thanks for the awesome generator!
The 6 textures are automatically mapped to the materials. Blender can natively open .gltf files, so you can import the file into Blender and export it to a Unity-ready format. There are also extensions for Unity to open it directly.
