Hello! Meshes in VR are perceived much less than in reality. Meshes were made in Maya in natural size, exported to fbx (meters). In Unity, Scale factor 1 (1 m File = 1m Unity). For example, the height of the Reichstag is 47 meters. All sizes are correct in Maya and in Unity. Cubes (the size of a meter) on the screenshot are visible on the left. Everything is also correct. The last screenshot from the Oculus Go. There is no more than 20 meters visually.
I tried changing FOV in OVRRig cameras, but it doesn't help. The trick with parenting camera to object and scale it doesn't work too. Are there any solutions?
