i found out something else:
BBI with transparency:
.tga .png show no transparency when set to “sky”
[.gif does not show up at all.] solved -> quicktime lib, see post above
And there is no need to hurry, eventhough i apreciate it. It isn´t imperative for my work at the moment.
I just noticed it, because i use BBIs as positioning mask for the renders.
It´s like the good old Civilization style… Isometric with surface fields and the buildings are “sprites” (yeah i am from the C64 aera) to be overlayed. and i load the surface as BBI to have a nice feedback if the building fits the landscape and if it sits where it should.
Works perfectly in 2.48x32 so i simply stick with this one by now
