You'd be better off using a second camera for your GUI. Position it somewhere away from your game arena, but not too far away from point zero or you'll get floating point inaccuracies.

eg.

Function CreateHudCamera( L_order, x#, y#, z# )
; USAGE:
; Creates a camera to be used for a heads-up display.

; PARAMETERS:
; L_order - This sets the drawing order of the camera. 'L_order' should be a negative number, so that the HUD camera is drawn on top of the main camera graphics. The highest value negative number will be drawn last (eg. The '-2' camera will be drawn after the '-1' camera.). Note that for negative 'L_order' numbers, z-ordering is turned off for this camera as a result, so the polygons being drawn should not overlap.

; x#, y#, z# - Set the camera's absolute world position. The position should set so that the camera and its associated 3D graphic objects do not interfere with any other cameras.

; RETURNS:
; The new HUD camera's entity handle is returned.


	Local L_cam = CreateCamera()
	PositionEntity L_cam, x#, y#, z#, True ; 
	CameraRange L_cam, 0.2, 5.0
	CameraZoom L_cam, 1.6
	EntityOrder L_cam, L_order
	CameraClsMode L_cam, False, True ; This prevents the background graphics from being overwritten by the camera's clearscreen color.
	Return L_cam
End Function

HUD_camera = CreateHudCamera( -1, 0.0, -500.0, 0.0 )
