The terrain of the world zone can be very large.
But beyond the grid in the top view, the terrain will be cut off and disappear.
Look at the top view first
Any object or terrain beyond this grid will disappear.
The next picture is an example
The circled terrain has exceeded the boundary
I place an actor at this boundary.
Next we play to view.
Terrain and actors have been cut off.
It’s normal in the world division.
The question I want to ask is, how to expand this grid?
