The Opacity map does not work in FS?

[Guest CHNGoldleader]

Hi every one,I am a newbie in creating FS scenery,thanks to anyone can help me with this problem.During my first project,I was creating a Logo signboard of an airport,which can use an opacity map to reduce the complexity of the model.So I use a BMP in diffuse map channel,it works perfect in FS,but the BMP in the opacity channel dose not work in the FS. The texure displayed in the game ignored the opacity map.Is there sth I haven't noticed in applying an opacity map?

Hi,If you want to make parts of a texture transparant, you need to add an alpha channel to this texture. This channel contains the information about which parts should be transparant.When designing the object, you just place the texture like you would do with a non-transparant one. If you are using FsX that is not completely true, you need to set a few options in the FlightSimX material for the transparancy to show. But I don't know which version you are using.
