How many triangles do you think a FPS game that is going to be optimized for mobile players should have for these categories of models?
Vehicles
Buildings
Guns
Props
In my opinion anything that is the closest to the player should be mostly given attention to detail with as it is the very thing they’re gonna see the closest in detail.
So in my opinion, Guns and vehicles should be mostly detailed in triangles, while the buildings and props should be less given the effort as the player wouldn’t be able to notice a difference on a building if you made it more detailed.
