I've added this question to a previous post on the design forum... but I think `Scenery & Panel design` is more appropriate... so sorry for repeating myself ::)
Could someone please tell me if there is a default pallet transparency colour for panel bitmaps, or does it have to be defined somehow in a cfg file?
I have re-textured a model of a Pitts Special that was designed for FS2002, but in FS2004 the cockpit panel has totally black window areas, although the gauges & dials appear in their respective `windows` on the panel.
