Motive VR scenes need a well-defined origin (0, 0, 0) for spawning assets or anchors. By default this will be Unity’s origin, however it is often useful to create an origin node in the hierarchy that represents the world origin. Typically we call this node “World” and add the “World Origin” script to it.
From there, when you import your environment model, you will want to configure it so that World’s 0,0,0 aligns with a logical origin for the environment. In particular, you’ll want the “floor” to be set at Y=0.
