Hi there. I'm building a game area and was thinking that to feel like you're "in the game" while looking at this scene on Sketchfab it would be nice to be able to attach objects to the camera. For example : I make a plane with textures on it that give an idea of the game UI (life bar, ammunitions level, etc) and I attach this object facing the camera. This way, wherever the user looks at your model, he'll always have the UI in position. It could be useful for other things I'm pretty sure, like a watermark always in the bottom left of the view, etc.
We can already attach lights and move them. Why not give us the opportunity of doing the same with one or more objects from the scene ?
