I'm doing a kind of a pin pong game, where the player is at the bottom, keeping the ball from falling. I absolutely need some of the 'Side walls' to be in 3D. I also made the player and the ball 3D objects with rigidbody to behave under physics. All the rest will be in 2D, like particle emitters, collecting objects, etc.
I don't want to show any object in 3D so I don't need the camera set to perspective. I need orthographic purposely, to show the 3D objects in 2D.
I just thought, what if tk2dCamera was optimized for sprites and planes and not 3D objects? would I'd be better off with Unity's Camera?
I would rather use tk2dCamera though, to display other 2D objects in the game in pixel perfect.
And would resolution overrides work well in this case with all objects? (If I understand well resoultion overrides is used for letterboxing, am I right?)
