I have set the transparent flag of a map entity to ON and am trying to increase and decrease the alpha to vary the transparency, but it doesn't seem to be working properly. If I set alpha to 0, it is invisible, just as it is supposed to be, but if I set it to 100 then it is no different to 50 (ie. it is still transparent, when it should be completely opaque). I have never had this problem with models. Is this a problem with map entities or am I doing something wrong?

Cheers,
Keith
