Have they been modified to work for JVS_Content rather than JVS_Doors?
Sucks that transparent doesnt work to well in blocklandActually everything uses blank.png and colors are definded by script. So i wonder if you could make a transpart color.
To make it invisible you just enter the color 0 0 0 0, like how 0 0 0 1 would be black, the last number is the alpha channel, which determines transparency. But it's impossible to use two colors at the same time, though.
