You dont need to change anything, but 3 things to watch:
- Using grip is fine with Oculus, but difficult with Vive. If your primary interaction is about picking up objects, you want to use trigger on Vive.
- Vive is tracked from floor level, Rift from eye level. You can change to behavior for Rift in settings and its a good thing to do, as things will be compatible.
- As the controller models are different, it’s better to use hands.
