I'm still working on it so at the moment still some changes are to be made.At the moment what I can say is this.If you want to have the "Free view" also using the next/previous unit view you have to do so.
-Open with S3D the file "Cameras".
-Then open the node 324 (Dummy_Cam_ObjectView)
-Then open the node 332 (Dummy_Cam_ObjectView1)
-Then open the node 334 (SphericalMove)
-Click one time with the left button of the mouse on the node 334(SphericalMove)and in the section on the right(Controller Name) change the default name to FreeMove(default name is SphericalMove)
-save
-Then click one time with the left button of the mouse on the node 335(SphericalMove)
-Once done click one time with the right button of the mouse on it and select "Delete" and delete it
-Then click again one time with the left button of the mouse on node 334
-Now click one time on it with the right button of the mouse and select this path:
Append new chunk/Properties(type:6/0)/SH3/CameraBehaviour/FreeMove
-Now open the new created chunk(should be numbered 335) and set these parameters(
set the parent ID exactly as in the image below):
-Once done all save it
-Then select the node 332((Dummy_Cam_ObjectView1) and in the right window in Node Positioning/Translation/Y: set the number 3,5
Save it.If you have done all correctly you have now also the free view when using the next/previous unit keys.
IMPORTANT:BEFORE STARTING WORKING ON THE FILE CAMERAS.DAT MAKE A BACK UP OF IT JUST IN CASE!!!!
