I hate to blow my own trumpet but oh my god, I am a genious!
The problem with the Mine Layer is solved!
I have not used AltImage or anything like that (I am still interested to see if we can get this working though.)
You can't cloak buildings without making them cloak generators so that was out of the question.
But CLOAK is also a veteran/elite ability that can be awarded.
By making the land mines trainable and a veteran/elite ability of only CLOAK, and making the Mine Layer start veteran, the land mines start veteran and start cloaked!
It's all perfect except for the problem that the Mine Layers must start veteran for it to work, but given the amount of time I've spent trying to get this to work, I'm as happy as Tanya in an armory.
