Camera orientation

[kgb613 21]

Hello, I'm doing a CV90 series based on ingame "warrior" model. I want to create an amount of camera, rear, left and right. For this I will need to create a kind of pad like we can see with BWmod or ACE for example. I absolutly don't know how I'll dot this but it's not the actual problem. 

To create my rear camera I'm doing ingame script test.

 

this setObjectTexture [0, "#(argb,512,512,1)r2t(uavrtt,1)"];
cam = "camera" camCreate (position myVehicle); 
cam cameraEffect ["External", "Front", "uavrtt"];
cam attachTo [myVehicle, [0,0,1], "zadni"];

I put this script in an billboard. And I put my vehicle with variable name "myVehicle".

Launching the mission, the camera is working but not like I want, because the camera is looking front of my vehicle and looks like not listening order to be in "zadni" position, the rear.

Here is the ingame screenshot.
