IXEG 737 Classic Plus - 1.5.2 Black object/shadow over pilot seats.

[Fly757X]

Hello!

I've recently started flying the IXEG in XP12 after finally making a concerted effort to move over from XP11. During my first few sectors that were all at night, I noticed that there seems to be a strange shadow/darkened object floating around the flightdeck, particuarly in low light (for instance no dome light). The object moves when I move the camera, it typically sits above or behind the flightdeck seats however in lower light, it tends to move closer to the windshield and cover more of the flightdeck.

When there is a flood light bleeding from the cabin into that area or indeed the dome light is on, the object is a lot less visible or not existant. There is also no sign of it during the day either. 

I've tried to re-install the aircraft, revert any art/shader modifications I've made to the XPlane/Resources folder and disabled plugins for tests. 

I've attached a few example photos with the line/object highlighted (I appreciate that it is very hard to see in some instances so I've given a rough outline on each example). 

 

I must appologies aswell for my description, I've depicted it as some sort of spectre, it's not... It's just a bit distracting in my field of view!

Thanks!

Hmm, thanks for pointing that out - I have just tried myself, and I can see those, too. It depends on the intensity of the "Background lighting" rheostat (behind the Captain´s control column), and I tried, but none of the rendering settings seem to affect it.

I will see if I can investigate where those "shadows" come from, for now the only solution seems to be to either increase or decrease the background lighting a bit more, they disappear once that light reaches a certain level. 

Sorry for that inconvenience!

Thanks Jan, 

 

Your help is greatly appreciated!

 Sorry I can not provide a better solution at this time - I also talked to Tom, and he also said that there is no quick fix for this, it seems to be an artifact of the volumetric lighting effect.

I have noticed this artefact as well. A few versions ago, sometime within the last half year…

By experimenting, I found that significantly lowering the (apparently undocumented) dataref sim/private/controls/lights/legacy_luminance_spills to values around 5–10 helps a lot. It does increase the already unrealistic light bleed from the overhead lights into the cockpit, but IXEG behaves like this anyway, and those lights can simply be turned off (at least in flight).

You can set it, for example, via a FlyWithLua script:

set("sim/private/controls/lights/legacy_luminance_spills", 5)

Awesome, thanks for sharing that!
