Nice, looks like you’re on the right track! I would just rotate the scene capture 2d to your leaning angle, and that will rotate the view as well. You could also just attach it to your actual gun model and it will rotate with it. If you wanted to do it via material for some reason, you would use the custom rotator node, and adjust the angle via a scalar parameter. Also, from your screenshots, you dont need transparency as a blend mode at all, it should just be a unlit and opaque
