Frustum Culling

ITsMagic uses frustum culling, also known as FOV culling, automatically and all the time.

This feature has been part of the engine since 2021 and does not expose a switch to disable it. In practice, there is no useful workflow where turning it off would improve the result.

Why you do not see it directly in the editor

When you preview a game through the editor panel, the editor camera is the one rendering the scene. That camera has its own frustum culling, so it activates the objects it can see.

Because of that, you do not observe the game camera's frustum culling directly during a normal editor preview.

To force the editor viewport to behave like the game camera for culling purposes, ITsMagic would need a dedicated debug mode that does not exist yet.

Why it matters

Frustum culling is one of the reasons ITsMagic can keep scene rendering fast.

Without it, performance would drop sharply, and in heavy scenes the engine would run at least 4 times worse.
