Inside of tunnel goed into sky?

hard to explain. I have a tunnel going through a mountain. About 1/3 of the way through, I am all of a sudden in bright white everywhere: above, beside, and below. I can see the trees on the mountain above me, but they are completely surrounded by white. The consist runs just fine through the tunnel and before exiting the tunnel, everything returns to normal.

I have the same glitch (that began last year with some patch) on "The Rivercide Electric Railroad". I reported it with screenshot, but there was no reaction from N3V.
 
Philskene doesn't use real tunnels. He runs the track through the terrain using tunnel portals and digholes. It is a way to get around the limitation of the angle limit that tunnel portals have to obey.

Autodctr, if the route wasn't made by Philskene, please identify the kuid of the tunnel or the route.

The route is of my own design and building. It is the single lane Eurotunnel that came with TRZ19. I have used it many times on other routes with no issues. I have it in use 5 times on this particular layout and only have issues with this one instance.
 
Hmmm, almost all assets are built using single sided polygons so it sounds like there is a hole in the tunnel lining or at least an area where some of the polygons need to be flipped. Seeing through the grid from under it is normal. Maybe a betatester will check it out and report it if they can reproduce it. Maybe the tunnel is turning at a sharp radius at that point? Just guessing really.

I had this happen sometimes when I would run Avery-Drexel on an underpowered laptop. Looking up at trees floating in the sky, I think it just did not have the oomph to cover all the rendering of the tunnel and the terrain.
 
That is totally enough! I can get by on ultra settings if I wanted to, but my CPU wouldn't be too happy....I once had 90°F temps while INSTALLING A CDP :o
I suggest reporting it to n3v and seeing what they have to say.

In case you're wondering, I use an RTX 2060 super, Intel i7 10700kf and 16gb of RAM.
 
Another interesting thing that I just found:

I tried to replace the tunnel: delete it and reinstall it. I cannot. The delete goes OK, but when I try to build a new tunnel, it boots me to the desktop as I am putting the tunnel in. 6 tries, 6 boots to the desktop.

Run a database repair.

Open the route again, but choose revert rather than continue.

Run Delete Missing Assets.

Try replacing again.

Did all that: still no joy. I get almost to the end and then I get to see the desktop again.

Have you tried a different tunnel?

After yet again another DBR and a revert, create a new single baseboard route and merge your current one into it. This sometimes fixes corrupted routes should this be the case. Note the "sometimes" because I lay no guarantees down with anything, but it's worth a try.
 
I have tried a different tunnel. Today, for some reason, it allowed me to build it kind of along side. I did this with the original one still in place and I made it quite a distance from the original. I figured that if I got it built, I could delete the original one and then slide this one into place. However, when I deleted the original one, I had a rectangular white spot on the mountain. You could zoom in on this and actually see into the base of the mountain! I am guessing it was, or at least looked like, a dig hole. (I have never used a dig hole, so I am not sure.) I tried leveling the ground around it, but I could not get rid of it. So, I reverted back.

That is a dig-hole object and they can be difficult to delete. This is their purpose to "punch" a hole through the grid. They are basically a 2-sided alpha channel asset that obliterates the grid texture on the ground-mesh. This is why you can see right through the ground and through your mountain with trees and objects above you.

Was this tunnel made up of separate pieces? Sometimes there are tunnel parts such as track with a tunnel, but that's only track. What you do is place the tunnel entrance and then attach the track to the entrance, or sometimes just run track through it. Once the track and portal is in place, you then use a dig-hole on either end to open up the tunnel in the hillside. There are various sizes of these dig-hole objects with Andi06's (RIP) being the original ones from the olden days.

To remove the dig-hole, I find using wire-frame mode (Press F9) to view everything as a grid. The dig-hole will appear as a very tiny dot or very small triangle. Once you find it, you can then tilt the camera straight up and delete it. Like I said, it's difficult to find and can be difficult to remove. If you can't find the dig-hole assets at all, then there's something wrong that needs attention because that means the original tunnel had one attached, but it didn't get removed when you deleted the tunnel asset.

I would try that again, and once you delete the old tunnel, but before you put the new one in. Run the Delete Missing Assets and see if that cleans them up.
 
The tunnel was the Euro tunnel (tunnel and track as one unit) that came with TRZ19. I have used it many times and actually it occurs 3 more times on this layout: all with never a problem.

I am going to add a couple baseboards and see what happens. If that doesn't fix it, then I may try deleting it again.

This particular tunnel isn't really for a train that I want to ride in: it is just to add to the sight-seeing route for the main line. If I can fix it, that would be great. But if not, I can live with it. I only found the problem when doing a circuit to make sure that everything was OK.
 
When you added baseboards, did you add them to the route, or did you merge your route into a new 4-baseboard route. The new route will reset the corruption (sometimes).
