I understand, but the shadow problem has to do with that specific onboard cam and view angle. When you press the "`/~"-button (the one next to the "1"-button at the left) ingame you can see the coordinates. With real time editing you change the onboard cam position. Play with it till the problem is solved. Make a screenie of the old and new coordinates and change the values in the gp4 tweaker folder when the csm mod is restored. Look for the onboardcamera and viewanglecam INI-files. Save the changes.
