Humphrey, did you copy/confirm the texture "gp_asphalt_Light.dds" into the texture folder companion to the scenery folder in which the airport resides. For whatever reason, PV4 did not display the expected "black" gp when the texture was missing. But, as soon as I suppled the texture, the GP appeared.
I that's not the issue on your system, try compiling FS8-style GPs. There are a couple unusual situations, depending on the relative locations of the GPs and ARP, where GPs do not display properly otherwise.
I also note that, in your initial post, the GP Editor shows as 2.2.16. That's 3 issues out of data, and suggests you are using an older version of ADE. The current version of ADE_GP includes a couple of fixes re non-display of GPs. I have no way of knowing whether or not those fixes include your problem, but the fact that your GP displays on my system suggests upgrading to the current ADE release might be helpful.
This time I try to compile with FSX SDK from my FSX.iso,somethig more weird happend: my GP has a white outline which can only be seen at night,and I think the invisible GP covered my taxingway lights(with “lluminate” checked).
it still made illumination textures only which cannot be seen at daytime,however these problems just happened on my new airports(which mean no any data in FSX) ,other stock airports are right to show GPs.
The problem is since illumination was unchecked why can't those GPs show at daytime?
The screenshot suggests the GPs are still being compiled for ground illumination. Perhaps there's some residual file in your scenery folder that's causing this or perhaps not all the new files are being copied into your scenery folder.
I'm out of ideas. All I can suggest is that you delete the contents of your scenery folder (to get rid of any residuals) and delete all the GPs from your AD4 file. Compile your airport normally and check that is displays properly - without any GPs. Then add the GPs back into the .ad4 file and try again - with Illumination unchecked.
One other point. You said you are using the P3V v3.4 SDK. I note in the GP manual that ground illumination is only available from P3D v3.5 onwards. I don't recall why, but the mention suggests there's a significant difference between 3.4 and 3.5 that affects ground polys. So, when compiling the newly-entered GPs, I suggest you check Generate FS8-style GPs.
