Choosing Transparency color?

[Dragoons Master]

Sub InitSurfaces:
find this:

Code:

' Set the key for masks
    Key.low = 0
    Key.high = 0

I'm not a 100% of how it works, I never realy changed it but it's a range, probly it vbcollors, so type vb+Ctrl+Space and try to change from collor to collor, I'm not a 100% sure it that will work.
