Creating a trigger for playing the animation in SteamVR turned out to be a little tricker then doing it for the FPS controller. For SteamVR it is required to enable Is Trigger for Sphere Collider located in HeadCollider (under FollowHead) in Player rig)

Still an unresolved challenge for me is to make unity bake 4096 lightmaps. For some reason, it would only bake 2048. I have tried manually Selecting The Texture-> Inspector-> Override for PC, Mac & Linux -> Max Size-> 4096, but it would still be stuck at 2048. Obviously, the lightmap setting in Lighting menu is set to 4096, but generating the map still produces the 2048 map. Still investigating.

Original Issue: Another unresolved issue for me at the moment are lightmap errors that produce weird spot/ dot like artifacts on some objects. Information on the web suggests that to remedy it, Generate Light Map UV's need to be checked or lightmap UV's manually edited, however trying those things did not fix it for me. FIXED: There might multiple reasons these artifacts appear, however, what helped me the most and cleared almost all of these artifacts was to change the following two parametrs in Lightmap Parametrs profile and experiment with them for your scene (You need to create the custom one): Pushoff value: Increase it to something like 0.5 Backface tolerance: 0.2 These value applied to my scene and may be diffrent for yours.
