T3D 1.1 Preview - Disable cast shadow in sun-object prevents prone-trigger (mvTriggerCount4) to update the view - LOGGED (THREED-1766)

Build: 1.1 Preview Pro.

Platform: Windows XP, 32-bit.

Target: Editors, Gameplay.

Issues:

After disabling the cast shadow option in the sun-object, there will be no screen (view) update in first-person, when activating or de-activating the prone-trigger $mvTriggerCount4, until you make another move. If you view in 3rd person then the appropriate animation is played.

Steps to repeat:
- Have a player-character with a prone-root anim.
- Create a mission with a sun-object and disable cast-shadow.
- Start playing this mission.
- Make sure you are in 1st person.
- In the console type: $mvTriggerCount4++;
- The view stays the same.
- Move forward and the view will change to the viewpoint from the prone-anim.
- Switch to world editor again.
- Enable cast shadow in the sun-object.
- Start playing this mission again.
- Make sure you are in 1st person.
- In the console type: $mvTriggerCount4++;
- The viewpoint has changed.

Suggested Fix:
Make sure it works again like in Beta3.
