VRIF or Interaction Framework seems nice, so it's on my wishlist. Not a fan of how it prioritizes Oculus support, but I read that it has some limited support for Vive and Index. VRTK v2 was amazing and v4 of that might be worth checking out during this jam. I also have a few other frameworks/kits I bought during recent sales that might be good. Lot of options out there for Unity!
