A brief explaination to all those shadow effect files:

the ALS shadow effect consists of 

1. the cube-map images in Models/Effects/cubemap
2. the new *.eff effect files in Models/Effects
3. the call to the effect files in the respective 3d model files Models/EC-145.xml (for interior, panel and glareshield)

in EC-145.xml add:

[code]
<!-- interior shadows on glareshield and interior fuselage--> 
<effect>
  <inherits-from>Aircraft/ec145/Models/Effects/bk117interior-shadows</inherits-from>
  <object-name>seat1</object-name> 
  <object-name>seat2</object-name> 
  <object-name>floor</object-name> 
  <object-name>intFrontdoorL</object-name> 
  <object-name>intFrontdoorR</object-name> 
  <object-name>stickleather</object-name> 
  <object-name>stickleather.001</object-name> 
  <object-name>interior</object-name> 
  <object-name>fuselage.004</object-name> 
  <object-name>fuselage.005</object-name>     
</effect>

<!--glareshield-->
<effect>
  <inherits-from>Aircraft/ec145/Models/Effects/bk117glaresh-shadows</inherits-from>
  <object-name>444</object-name>     
</effect>

<!-- interior shadows on main instrument panel -->
<effect>
  <inherits-from>Aircraft/ec145/Models/Effects/bk117panel-shadows</inherits-from>
  <object-name>panel</object-name> 
</effect>
[/code]

Note:

The MFDs bezels are now directly integrated within the mainpanel model, to simplify shadow cubemap definitions. 
Therefore they do not make use of individual effect files anymore, previously located in /Models/instruments/EUcopter-mfd-c/Effects .
