GEK_the_Reaper

@embraceentropy From your shots I see you used Delta livery. I tried both available Deltas and this is how the cockpit looks on my end: This picture is taken at DUSK! This one is daytime! I think that the only solution you have is to hit that Delete Generated Files button or to try a Repair on P3Dv4 (both actions could lead to loosing some of your installed AddOn's if they are not installed with the XML method).

@mopperle calibrating the monitor would not help in this case since the picture he posted is realy dark on my end to... @embraceentropy I think also think that something got messed up in your P3D config. REX TD and SC should not have impacted the cockpit. Something interesting did caught my eye in your settings: Shadows Casting and Receiving! Can you disable some of the internal stuff? Also you have External Vehicle to cast shadows yet there is no aircrasft shadow seen in your first post....

This is way too dark indeed. What REX AddOn do you mean when you say "After restoring defaults in REX..."? Are you certain you have not applied any other shaders like PTA, ENVSHADE, Tomato, (Cucumbers <- this is a joke),...? What about HDR lighting in P3D? Is it on?

This will help you when looking outside through the window ;). Can you maybe upload a picture of the "dark" cockpit? Do you use some shader modifier?

@colz99 I can confirm this oddity. This is indeed strange and a case for @Hans Hartmann Just tried different approaches for changing the SID and all of them failed. I don't know if it's something to do with the latest update since I have not flown the CRJ a while now (due to X-Mas, family and stuff).
