The file JFK_det_02.bmp is a bitmap made to show concrete and is used where that is displayed on top of the photoreal bitmaps. Its 1024x1024 pixels and used in a repeat pattern, and its replacing 90% of the photoreal bitmaps at the locations its used by use of alpha. At the same time the big photo bitmaps (JFK_Txx.bmp) are also 1024x1024 pixels, and covers everything with JFK_det_01.bmp on top of taxiways and runways to try and help with the fact that its photo and get blurred up close.
That exactly what I've said.
What you are keep missing the point, is that NONE of this is relevant to the issue YOU posted in the screenshots.
The issue you posted in the screenshot, as to prove a point that parts of the ground are blurred and parts are not, it's NOT due to this, because you are showing a place were concrete meets asphalt, and the asphalt looks AS IF was blurred, when it's not.
And, as I've said several times already, asphalt and concrete are made with the SAME method, resolution, and meters/pixel ratio. The ONLY difference, is the detail texture used. Period.
Had you showed an area were concrete met GRASS, instead, then you would have been correct because, in that case, grass doesn't not have any detail on top of it, so it is expected that it would look blurred.
If you had made a file similar to JFK_det_02.bmp for the asphalt covering runways and taxiways the whole thing would have looked a lot better. Problem then is that you will have a hard time showing all the patching of asphalt over the years.
That EXACTLY what I've said, and it's exactly what I DID, with the replacement texture I've posted, which replaces JFK_det_01.bmp, that is used as a detail for the asphalt.
So, said, it's NOT a matter of "covering different areas with textures at different scales" the issue, it's HOW is made the detail for the asphalt.
I could probably do the same to the det_01 file too and it wouldn't make much difference to taxiways and runways.
Why you don't simply try the det_01 I have posted ?
The fact remains that the photoreal background is going to look blurry up close because of the area each bitmap covers
No, if you are refering to what you showed in your screenshot, that had two areas made exactly in the SAME way: low res photoreal background + detail for concrete AND the SAME low res photoreal background + a DIFFERENT detail (at the SAME res, though) for asphalt.
The scenery is the best there is for JFK, and pretty much impossible to improve without killing 99% of users graphics cards.
No true. As I've said, it was just a matter of improving the asphalt detail texture and make it stand a little bit more, which is exactly what I've did, and the results clearly show this. This is the same scenery, with JUST the JFK_det_01.bmp replaced, with the same file I've posted before:
JUST by replacing the detail texture (which is what I was saying all along), the transition between concrete and asphalt now appears to have the same resolution, and asphalt doesn't look blurred anymore.
