Hello. Im using forward rendering for a VR project where i fly a drone. I was wondering If i can achieve a postprocess effect where all the environment fades except of the drone. I want to implement a loading level system where you can see just the drone and the UI deck of the drone where you can press buttons to start a new game. Everything is gray or any color around the drone then the levels loads and I want to fade into the level to slowly starting to show the loaded level.
I tried playing with the stencil buffer and I made a potprocess material where I check if the stencil is the value of the shipmesh and if it is just output the sceneTexture (postprocess) and if not just output the gray color. The problem is that instead of the pixels for the ship mesh I get the scene rendered from the camera and it moves based on my camera its like the scene is projected to the mesh.
Any tips how to do this properly ?
