Follow up ,
If you run into an error when hitting into the " Brush " or "trees " and you get that grey box ( Null and Void ) boxed error code. Heres how to correct that .
To define it , the game error is telling you that on 3D scripts ...there is a void area where there is nothing to fill in for that space , no sound , so its
" void ".
I narrowed it down to this.
Its the Main soundscript your using , and to fix it you have to delete the voided script area which is labeled " Open " .
Because the game is coming across that area knows not what to load for it becuase its Void .
It looks like this :

Highlight it and delete it .
Go through all your post shots , preshots , reaction .... just anywhere you see open , its open for the game to either interprete the sound on its own , and open the next scene or play the sound in the next scene and get an error . ( This is open for interpretation )

Note : Before you do anything else make sure you have a backup for this soundscript , in case the remedy does not help , or causes more problems .You may have to replace the soundscript with the original sound script again.
Its a process of eleimination of what is causing the sound error to begin with .
In my case , it fixed my sound issue right away , and when i hit the trees and brush , its playes either no sound or goes to the next scene .
If in any case you get a different reaction you can always put the Original Sound script back in its place .[/b]
