Question

I was searching for methods to optimise my game.

I was thinking if there is a way to not draw the objects that are in the camera view but are not visible to the viewer?

The thing is that i need to lower my draw calls and at any given time, there are at least 12 game objects that are not visible to the camera. Can this be done?

Answer 1

What you are looking for is called occlusion culling and it’s a built-in feature in Unity. In order to lower the number of draw calls there are some more techniques interesting for your problem:

• Frustum culling
• Layer specific culling
• Texture atlasses i.e. several different objects share the same material
• Static and dynamic draw call batching
• LOD (level of detail)
