Flickering green lines

It does not make any difference.

Can confirm, at certain angles it looks ok but at others I see such artefacts as well. Turning autogen trees off fixes it, even the worse case (FSDT KLAX in my case). I also had OrbX trees and uninstalled them, it didn't make any difference but could be still related.

Is the ORBX PABR you are using a freeware airport?

Have you asked ORBX Support ?

This is P3Dv4.5 default PABR (autogen vegetation in use) on my setup (screenshot).

Note:
I do not have ORBX trees.

[AKar]

Having that specific airport appearing in that pair of screenshot is irrelevant. The issue occurs regardless of whether being on an airport or not as long as there is autogen vegetation.

As venzi noted, Orbx trees may be related. However, uninstalling it appears to make no difference.

Why not uninstall addons and P3D then do a full reinstall of P3D?
Leave P3D in a default state (no addons) for all testing.

Might be quicker than troubleshooting, just a thought.

Well, I reverted back to v4.4 client for now. It appears to make things work again, and was a fair bit faster than re-installing all the fun stuff. :)

OK after a further flight I can report that I think I can confirm autogen vegetation is the problem in my sim

as others have found only autogen vegetation creates the issue
I can turn all autogen sliders up with no problem but autogen veg must be off.
if I vary the autogen veg. it is bad at altitude and gets worse on the ground

so it seems somewhat linear with altitude.
Makes sense, more trees on the ground!
If I leave it off completely the problem disappears

Is this with default scenery / airport(s) in your test?

[DLRobinette]

It is something to do with the Autogen Trees. I can turn the other Autogen sliders all the way to the right, with no problems. The minute I turn the Autogen Trees to SPARSE, I get the 'rips' in the scenery.

I tried it with stock F-22 at Elgin AFB and then on active rwy at KSTL. Same results both times.

I do not have ORBX trees active at this time, or any ORBX products.

Ran into the same issue after updating Content + Client to 4.5.


Turning down the Autogen density slider to none also prevents the problem in my case.

Which airport, aircraft, scenery (default/payware?) is in your screenshot/test?

Do you have Orbx Trees installed?

[niels95]

Tried on both Payware and default airports, screenshot is at the default airport on the Gulf of Mexico (dunno the name), same results. the issues does seem to increase when theres more trees in the vicinity.

PMDG 737 (but same with default f22)
FTX Vector/Global/Trees (issue persists when they are turned off)

Steps taken:
- Deleted prepar3d.cfg
- Deleted shaders
- Autogen density to none (removes the issue)

My thought is Orbx Trees has modified something (files) on your system.
I do not use Orbx Trees and all ok here with PMDG737 and other Orbx Regions/airports / Win7-64 / P3Dv4.5 Academic.

[niels95]

The problem with that hypothesis is that i didn't touch FTX trees before/after the 4.5 upgrade.
Reinstalling the entire sim would be a logical next step i think. But bc of the time involved i'll wait a few more days for any potential fixes popping up from the community/LM. At least good to see i'm not the only one with this problem.

Thanks.

You mentioned upgrading your P3Dv4.5 Content.
Did you also Upgrade the P3Dv4.5 Scenery product to v4.5?

Have you contacted Orbx Support?



My uninstalling P3Dv4.4 modules, downloading the 12GB P3Dv4.5 ZIP, installing Client, Content and Scenery took about 1 hour.
After the P3Dv4.5 install I had one problem with Orbx KSAN. Extra taxi signs were appearing. I contacted Orbx support and they had me turn On an option in KSAN's Options configuration to fix it.
A few of my payware products needed their normal P3Dv4.5 updates. All ok.

Edit:
After your P3Dv4.5 update did you run Orbx FTX Central to check for problems?
