Repository Again - Falling Water Set...
the master name is actually: fullengthwindow2 and I believe the SHPE parts should reflect this.
Perhaps you did not commit the changes you made? Anyway, try it and see if that works and if it doesn't, please let me know and I'll try slaving it as well from the original files; that way we can stumble through the dark together. Good luck!
Going to check if that makes a difference.
The frosted glass, and wallshadow alpha is keeping the texture from window3, so that's ok.
Your reply actually helped me work it out.
What it ended up being was that I had gotten too carried away and changed the meshname in the STR section to Window2, instead of leaving it as Window 3.
