Real NZ Dunedin flashing ground textures

Postby toprob » Mon Jul 15, 2019 10:02 am

This was reported recently, and I did put it down to the Prepar3d v4.4 scenery display bug which was fixed in 4.5, but the guy who had the issue updated and it still didn't work. So I'm sorry this has taken so long to acknowledge, but I'm never been able to replicate the issue.
Following the issue with NZCH's flashing ground polys, these were tracked down to the custom runway at West Melton, which I promptly removed from the release version. Which ended up as a bit of a nightmare, but I'll cover that separately...
It may be that this is a similar issue with Dunedin. A discussion over at AVSIM has just had a post which certainly points to this, as he was able to fix the issue by disabling the ground polys at Taieri. This isn't a long-term solution, as Taieri is my favourite airfield, so I will see if I can track down a cause, and release a patch for Dunedin if possible. This will take a few weeks, as I have some tedious family commitments for a week or two.
This issue seems to be new in later releases of Prepar3d v4, but I'm not sure if it is something which LM may see as fixable.

Thanks Rob,

I installed Dunedin today in P3D4.5 and noticed the odd ground thing that you're referring to, where it seems to alternate between two different textures. It will be great if you can find what's causing it. My Dunedin is V1.11, - is that the most recent?

I really like Taieri too.

Haven't flown into Chch yet.

Just flew out of Christchurch, - no problems with ground textures there, - absolutely stunning, clearly a labour of love. Well done :D :D :D :D !

Really interesting to see the post-quake appearance, - must be unique among flightsim landscapes.

I'm actually away this week, and I don't really know when I'll be back, but I will look at a solution when I'm back. It may be a similar issue to the pre-update NZCH -- a nearby airfield, which shares some ground textures, in this case Taieri. I'll see if replacing the shared textures makes any difference.

Just to keep you informed, although no solution as yet.
I was thinking that this issue was caused by 'reusing' textures in two close airports, in this case NZDN and NZTI, but I've now made all textures unique to each airport, with no change. Since disabling the ground textures at NZTI fixed NZDN, it does appear to be a bug in Prepar3d v4.5, similar to the bug in v4.4 which was mostly fixed.
I will see if the NZTI ground polys can be redone without affected NZDN, but at the moment I'm a bit stuck.
