Game Object Backface Optimization for Mobile
Hello, It has been a while since I have worked in Unity. So I want to get updated on optimization for mobile.
My game has a locked camera angle so the back side of the game objects will never be seen by the camera. Is it worth spending the time and effort to delete the backside of game objects which will never be seen by the camera or does "Backface Culling" take care of this entirely. I understand that the backside won't be rendered but I have read that the overall polygon count will still effect overall performance. I not sure if this rule still applies.
A good example would be a isometric game built of blocks. A single scene may contain hundreds of blocks. By eliminating the back side of the model would cut the polygon count in half.
I know that Monument Valley developers deleted the backside of their models but If it doesn't make any difference anymore I rather not waste my time doing it manually.
Thanks in Advance- Raymond
I would think that backface culling is very fast on most devices since the face gets culled before it becomes a fragment. It is however not free so if the mesh has a lot of vertices you may gain a little increase in performance.
