About Path Camera in Torque 3D

I want to create a mission preview. I already got some helps from the following the thread of the forum. Currently, I can use the "Path" and "Path Node(Marker)" to make a camera track and the camera will go correctly along the Path. But there are still some problems with me.

The first thing is how to intuitively(WYSIWYG) control the direction of the PathCamera in the World Editor, although I know the camera's direction can be adjusted by changing the Marker's property "rotation", but that isn't intuitive (What you see is what you get) in the editor. So, is there any better solution to edit the camera track(include camera direction)? Or shall I have to make that by the current way, even need to code for directly controling the camera object? Could anyone give me some suggestions?


The second thing is that a "Fatal Error" will happen when the property "isLooping" of the Path is set to "true" and the camera repeatedly run along the path many times. The following information is from the file "console.log". Does anyone know that reason?

engine\source\core\stream\bitstream.cpp(212) : Fatal - Out of range write


Thanks for any help in advance.
