So im working with a few games that will need minimal memory usage when it comes to their builds because of the size of the games. I have always wondered this and really do need a clear answer, it would be great if it was a little more open information for me.
The question I have is about grouping, and union fidelity. Take the picture below for example, if I unioned all 4 bricks, and set the collision fidelity to box, would it take up less processing in the game than if I were to just group the four bricks? I know that its less of a complex shape the processing system has to deal with after turning fidelity to box, but is is better than grouping?
