CameraRange:Void camera:Int32, near:Float32, far:Float32

Parameter	Mode	Type	Default	Description
camera	In	Int32	required	Camera handle.
near	In	Float32	required	Closest distance that is drawn. Must be greater than 0.
far	In	Float32	required	Farthest distance that is drawn. Must be greater than near.

Description

Sets the nearest and farthest distance in front of the camera that is drawn. Anything closer than near or farther than far is clipped away. The defaults are 1 and 1000. Raising near and lowering far gives the depth buffer more precision where it matters, which stops distant surfaces from flickering through each other. BlitzLLVM draws with a reversed float depth buffer, so the precision is nearly even over the whole range and this is rarely needed. The distance is measured along the view direction, not as a radius around the camera. The runtime stops with an error unless 0 < near < far.
