think it's done through animation somehow, cause look at this
Code:
; ------------ blinky production lights -----------------
Draw = W3DModelDraw ModuleTag_02
DefaultConditionState
Model = None
End
ConditionState = ACTIVELY_CONSTRUCTING
Model = ABArFrcCmd_A9
Animation = ABArFrcCmd_A9.ABArFrcCmd_A9
AnimationMode = LOOP
End
End
my guess is that it's animated to flip planes over... so you have textures on one side, and the other side has nothing... just a guess though
