Strange lighting issue P3D v4

Recommended Posts

Hi guys

Is this normal behaviour?  When I pan around the light source changes from light to dark.  I use Ezdok but the video demonstrates the same change of light in the Locked Spot view as well.  At first I thought it was a configuration issue with PTA but I have reverted back to default setup in this regard but the problem persists.  The time in the sim is about 19:30GMT if that makes any difference.  I've not done extensive testing during different parts of the day to see if I can isolate the issue yet.

Any ideas?

Cheers

Yeah, it's normal. It's because you are in a cloud shadow, then look away from said cloud it stops rendering, i.e being culled for performance reasons, then the shadow also disappears. Get the cloud back into view and the shadow re-appears. It's an issue that goes all the way back to the implementation of cloud shadows and I doubt it'll ever be fixed. One can hope though, as it's very annoying.

urgh that's pretty bad then.  I'm new to P3D, jumped across from FSX SE.

Thanks

Thomas: do everybody a favor and post this over at LM and see if anyone can/will look into it. We may have a better chance if LM themselves sees this...

Definitely post on the LM forum, they may eventually get round to it some day.. The more people that complain about it the better! :)

It's my biggest gripe. (quietly, of course)

Yup, it's a bit of a bummer for sceenshots I've found, just when the lighting looks great, you tweek the viewpoint to get a nicer angle on spot view and suddenly the lighting isn't as pleasing from the new angle. It's not a showstopper, but it could do with perhaps some kind of blending from one setting to the other when the viewpoint shifts.

It's indeed my most annoying thing in P3D... this and the cloud shadows sometimes popping in and out when you pan the view around which i assume is related... they should add a quality slider to draw more shadows should your hardware be capable to try and alleviate this... we can but dream anyways..

Fair enough. In the outside view. But exactly the same happens in VC. And even worse, also the cloud ground shadows further away from your plane show this behaviour...

So posted over at LM and got a reply saying PTA could be the issue.   I've restored default shaders and will investigate further.
