Don't be a dope like me and go changing transparencies without checking inside the file what is and is not transparent...

Screwed up most of my maps and had to reload them afresh in virgin unchanged format, LOL!

Using IMGTool I was able to (finally) see the individual settings before messing around with them.

The pic below shows the non transparent parts of the file [important]!

Hence look before you leap... and always keep a virgin backup copy!
