I want to make an animation which is a first person perspective with augmented reality. I need to have a triangle indicator above an object inside a room. I was just going to do a triangle image on a plane parented to the object then use track to constraint to keep it facing the camera. What I don’t know how to do is make it so say, the camera is outside the room in the hallway, I want the triangle to appear in front of the hallway wall.
I guess I could render the animation, then copy the camera and it’s animation to another layer, which just renders the triangle image, then composite them together. If there is another method without compositing, I would prefer to do that. Any ideas?
