Render two scenes separately, then blend them at runtime?

Hello everyone,

I am trying to make a VR game with smooth locomotion and want to have a “static scene” that never moves and is shown only when the character move (so the player will not get dizzy because he will have a static reference point).

I currently have something working using the linked tutorial, but I have to update the material property for each object in the “static scene” and the static and real scenes are rendering together, meaning that the reflexions of the real scene take account of the “static scene” (and i dont want that to happen).

Is it possible to render the “static scene” alone and blend it in only when we move? Should I use render targets?

Thank you for your time and interest!
