Hi,

I've not seen it anywhere other than when developing my route, from my experience it looks like there is a tunnel occlusion box which is geographically too high so that it shades the surface scenery.

It looks like there is a junction station in the top middle with a line diverging from the main, if that is heading into a tunnel then it is most likely that it is the occlusion for the tunnel which is sticking up. They're fiddly to get right - you'd need to find the double green arrows buried underground (the torch helps sometimes), double click on them to select the box, and shrink the box down so that it doesn't show above ground to fix the issue. This can leave bits of the tunnel interior exposed from the shading, so sometimes more than one tunnel occlusion box is needed, especially if there's a steep gradient involved, or else a lot of fiddling with the angles of the one occlusion box...

Is this a WIP route of yours, or one from another developer, or from a finished route? I think I've got the right term 'occlusion'...

Hope this helps,

ThePhantomPhish

cheerrs for that.. it's in my Chinley Route.... seems to move round with the sun... that picture was taken at midday, if I change it to 15.00 it's moved to the hill behind the station.
If I import terrain 1x1 say somewhere it will disappear but come back when I "reload" scenarios.

I think that's what I've seen on the Isle of Wight V7 steam route near Ryde it shows up at certain angles near the station.

I never considered it might be to do with the tunnel occlusion.

Is there a Nissen hut by Mundo in the area?

Tell me more! I have had similar problems on a couple of routes I am building, and I have used Mundo's Nissen Huts. They may even be in the areas affected!

No Mundo stuff, I even uninstalled his stuff but still there.....
If I change the weather to rain (no sun) it's not there.
Something gets into the way of the sun at that particular point, very specific point too.
I've panned up into the sun and gone down underground, nothing there...
Checked the the tunnel occlusion on the couple of tunnels I used it on.
Just have to keep trains out of Bakewell at lunch time...

I deleted the scenarios in which it appeared after I noticed it did not show in one.
Then I created the same scenario and it is not there anymore.
I'm in touch with Dovetail but it seems just one of those things sent to test us.

I've got this problem near West Hallam on The Friargate Line. I'm not saying it isn't a tunnel occlusion in the wrong place but I have no idea why it would be as there isn't a tunnel for a couple of miles. I am using Nissen huts, though I can't remember whether this was there before I used them.

I had exactly the same graphical problem at Swansea when working on the South West Wales route; nobody else involved suffered from it so I concluded it was a 'duff' file on my system. By deleting scenic items I found that removing the half a dozen or so instances of the cream Nissen hut the corruption disappeared.
Placing those 3 assets in a new blank route also brought forth the same effect from the cream hut, so all I did was copy the .bin and .GeoPcDx files from the dirty (I think) version and edit them to point to the files for the cream version. I can't remember if I ended up producing another .TgPcDx file also.

A quick test would be to rename your Mundo assets folder to Mundo.X (or whatever makes sense to you) effectively *breaking* the path to the assets to make them 'missing', so all that would be displayed in game is milk bottles.
If the shadow disappears you know you're on the right track, if not you've only wasted 5 minutes.

I have had this problem with nissan huts too and eliminated it by removing them in several routes.

But the same exists near Settle on the backdated S&C route too and I am pretty confident there are no nissen huts in the scenery so they do not seem to be the only object causing this problem. I removed quite a few things temporarily in that area with no success.

I'd agree with that; for example the 1950's Railwaymen figures for the IoW cause problems---the price of the game getting updated and older assets being 'left behind'

Found the culprit on my Chinley Route for the shadow.. it was Decapods "Timber Coal Stage"

https://www.facebook.com/jetgriffsTSRou ... =3&theater

Discovered this purely by accident when adding it to a new Route "Westerham SR" I am doing... just inserting it into the coal yard and bam... black shadow.
Went back to Chinley, deleted it from Bakewell yard and it took the shadow with it....

I can confirm that Mundo's Nissen huts (UKTS 23137) do cause this effect but, in my case at least, the addition of a single example doesn't. I had used the model numerous times for the West Hallam Storage Depot on The Friargate Line but hadn't noticed when the shadow appeared. In the last few days, working on the area around Kimberley station, I discovered another camp - Cloverlands - which, I've been told, was a training base for the Catering Corps. It had umpteen accommodation buildings that I assumed would have been Nissen huts and used Mundo's models again. I had to scale them to fit the footprint on the OS map decal so I used the copy-and-paste function to keep the size and LOD setting constant. I'd put eight or nine in place when the shadow appeared. Deleting the last one made it disappear and adding a new one from scratch did not bring it back.

Peculiar!

And the shadows are inconsistent in when they appear. I just loaded TS for the first time today, tried to find an errant shadow at both sites for a screen-grab but found none at either! There's clearly more to this than meets the eye.
