Black squares during day time

Recommended Posts

Dear people of our community,

I got a question. At the time of departing of SFO I've seen some black/different squares. It is during daytime. (23.01Z) which is 15.01 local time. But the squares are like evening time. Very weird. I don't know where this come from.
Please check the screenshot.

Do you know the issue?

Dear regards,

Had exactly the same problem last week - updating to the latest Orbx Central (I was on an ancient version) and then letting it update all my products sorted it out !

I had the same problem with an Orbyx airport - and Nick Cooper solved it for me

That's where the lights are at night


No, the OP is running P3D--your problem and the solution in the link you provided is specific to FSX only.

The dark ground polygons are night landclass textures, and usually their appearance in daytime is caused by either the ORBX Open Landclass mappings getting crossed up, in which case uninstalling and reinstalling your OpenLC products usually fixes that, or alternatively you might have an incompatible (with OpenLC) landclass file included somewhere in an add-on scenery which references the original P3D class mappings--in that case you need to go find and remove or rename the offending landclass bgl file (e.g to xxxx_LC.bgl.off) in the scenery.  Usually the file in question has a name with "LC" somewhere within it.

Verify your ORBX scenery files and check the ORBX scenery order is correct, Base Scenery OLC is below your ORBX regions and airports.

Thanks for the reactions. I am right now at home. I will check tomorrow. After a long flight, we all want to sleep all day long. 😛
