Ultimately, I'd prefer to not have to "play" with a copy of an existing WinFX shadow files.
Looking at the existing shadows might be your best bet. They seem fairly simple.
Three images for left, right, and bottom.
A text file describing them.
Sample:
[Shadows.right]
Image = dual thin\right.bmp
TopHeight= 15
BottomHeight = 18
LeftWidth = 1
RightWidth = 11
TileLeft = 1
TileTop = 1
TileBottom = 1
Tile = 1
[Shadows.bottom]
Image = dual thin\bottom.bmp
TopHeight= 0
BottomHeight = 13
LeftWidth = 14
RightWidth = 5
TileLeft = 1
TileTop = 1
TileBottom = 1
Tile = 1
[Shadows.settings]
;BaseAlpha = # (0-255) sets defaults alpha blending
baseAlpha = 200
Sorry, couldn't find any tutorials.
As Per-pixel windowblinds have become the norm, WindowFX shadows have fallen by the way-side since they can't be applied to them. I think it's too bad. I really liked custom shadows (but I like the newer skins more).
