It is a relatively common problem I think. I just tried the demo version of the Drzewiecki-design Tallinn, EETN, from the AVSIM library. As is so often the case with these 'problem' airports, if you start off from there, the texture usually behave normally. Most often it is when you arrive there that you see runway/ground/apron textures roll or peel back in front of you as you taxi. Sometimes making a flatten file helps, but why does this happen, and especially, why is it usually only upon arrival that the problem shows itself?

That's a question I've wondered about for a very long time. Finding a fix-all would be great, but I think it's different in each circumstance. Anyone with some knowledge of this please enlighten.

It is because of a difference in altitude between AFD File (AFCAD) and ground.

That is why usually a "flatten" will help, because AFD and ground are "forced" to the same altitude.

It has to be done for each faulty airport because the flatten file has to be told what altitude to use.

Thanks. Yes, that's what I've always done in the past, so I'll have to continue doing it I guess. You'd think that this wouldn't be a problem with airports from well-known (payware) developers...

 

Doesn't really explain though why flying into the airport usually shows the problem, whereas loading the a/c at the same airport for departure rarely does.

Do you have scenery casts shadows on? I find this removes certain texture problems at certain airports.

Thanks, no I don't have that selected.
