Stu Antonio Posted July 11, 2021 Share Posted July 11, 2021 I have some strange shadow areas on the ground that change with the view angle. This happens in external as well as internal view. I've seen this on landings, during taxiing and on stand at several 3rd party airports. Changing the shadow quality and draw distance does change the shadows a bit, but doesn't resolve the problem. Does anyone know what may cause this? Thanks Quote Link to comment
Henrik Lieb Posted July 11, 2021 Share Posted July 11, 2021 These are cloud shadows, you use envshade right? It's a bit bugged in 5.1/5.2 currently. 1 Quote Link to comment

Yeah, I niticed turning cloud shadows off „solves“ it. Correct, I use envshade. I‘ll wait for them to fix it then. Thanks! Quote Link to comment
Atul Mishra Posted July 12, 2021 Share Posted July 12, 2021 Yeah. I think it's envshade as well. I've had this since V5.1 actually. Not sure if others did. Quote Link to comment

Thanks for the info, can you give me the exact time and date? I try to recreate this, cause it never happend to me, thanks. Quote Link to comment

Okay, I was able to successfully reproduce this (aircraft doesn't matter): Try July 08th 2021 at SimWing's EDDM stand 330 with historical weather (ActiveSky: EDDM 080920Z 30004KT 270V350 9999 FEW007 SCT010 SCT025CB 19/17 Q1020 TEMPO BKN010) I got the strange cloud shadow effect there. But I admit, this can have so many reasons. AS settings, SkyForce settings, P3D setting... but who knows. Quote Link to comment
Matt Richards Posted July 15, 2021 Share Posted July 15, 2021 I’ve seen on another thread somewhere that it’s caused by Activesky. Not sure if that’s correct as I’ve not had time to test it yet. I’m using stock shaders and I’ve seen it with those. Quote Link to comment
Stu Antonio Posted July 15, 2021 Author Share Posted July 15, 2021 Yeah, it's obviously related to a specific cloud situation. I don't have this effect in 90% of the cases, but if the cloud coverage is just "right", these things appear.... Quote Link to comment

I wasn't able to recreate this sadly. Here is short video: https://streamable.com/sksxgp Okay, thanks for checking. I was able to narrow it down with a user over in the LM forum. I could also reproduce it on the default situation with a overcast stratus layer 800-1200 ft. It appears that as soon as the viewpoint (external or cockpit) "touches" the cloud layer, the visual bug appears. Even if no clouds are visible, the bug can still be seen when the system creates a very low cloud layer. In my above situation at EDDM, you can see FEW007, so my guess is that this somehow produced the error. A very low cloud layer by ActiveSky. My approach now is to increase the "P3D cloud offset" in ActiveSky (which was "0" before) in order to prevent very low, close to the ground clouds.

Bernd Edlinger Posted July 27, 2021 Share Posted July 27, 2021 I see the same and it drives me crazy sometimes It also looks like its a Rex SkyForce bug as you can see here: https://www.avsim.com/forums/topic/603797-strange-shadow-line-was-there-ever-a-solution/ AS Cloud offset helps a bit, but not everytime :( Quote Link to comment
