Found a repeatable bug with the HorizonX Photoscenery this evening.

Flying over Aberystwyth in Central West Wales I get a repeatable crash almost directly over the town. Doesn't happen if I disable the photo scenery. Does happen in any plane at any speed/alt etc.

Anyone ever had this?

I flew for hours over the rest of Wales and Devon without issue. As soon as I returned directly over Aberystwyth I get a CTD.

Wondering if there is a fix

Does anyone know how to find which scenery files are effective at a specific location? I'd like to replace just the relevant files instead of doing a full reinstall if possible. Looks like its Volume 2.

 

 

What does Event Viewer display?

OK I sussed why it was crashing.

One of the update scripts for the Horizon X scenery had renamed one bgl file to disable it, and failed to replace it with a new active one. Several others examples had been correctly updated, but the tile for Aberysthwyth was missing. Checked my backups and I don't think it's ever been there. Obviously I never flew over that specific tile previously in all my years with this data. 🙂

For anyone who wants to check their installation... Look in:

...\VFR-Gen-X-2.0\Volume2\Area1\1.2m Photo\Scenery

for a file called V2-12-11750213.bgl

It's probably missing, having been renamed v2-12-11750213.bgl.VFRGenXUpdateInstallBackup

Simply rename that file to the original name V2-12-11750213.bgl and you should not get the crash.

I can see why they tried to update the file - it doesn't draw quite right in the scenery, but I'd rather have a slightly wrong looking tile than a CTD.

Cheers.
