Ok, why did this occur. black boards all over the route,

[dangavel]

I'm still using SP4, but i do not think i'll be doing so from now on. worked on my route for a couple of hours today , when I noticed that some areas were appearing black from a distance, but the textures reappear when I zoomed in closer, tuns out the entire route is now like this, will have revert to an earlier version, lost about a days work . I'll completely reinstall and then update to sp5 . If this happens again i'll just give up and find another activity., I am fed up of this sim to the back teeth. Anyone have any idea whats going on, ive done extended database repairs on a very regular basis, about four in the past week as assets keep on getting texel issues and are labeled as faulty. The install is only a few months old.

Not seeing anything like the above images in Trainz Plus, Trainz Plus (current beta) or in TRS22PE. All are the latest (SP) versions.

@dangavel what is the GPU?

I updated to sp5 and It appears that any of the versions of this route made in in sp4, even if they seem ok in that version, when imported into sp5, they are simply not workable, the terrain renders but then sections rapidly disappear, in reverse, so the terrain appears and then vanishes whilst coming nearer to the viewer. objects do not appear to be affected but are floating in space. ive done an extended database repair, no fix. .
the dem i used for the extension to this route was created in an early version of 2022.I've been working in 2022pe sp4 with few problems up til now , has anyone seen this issue when upgrading ?
looks like I'll have to scrap the extension to this route that was originally made in trs 2019 and start again unless there's some sort of fix .I understand that nv3 wont help with these sorts of issues, which i think is a pain as I bought sp4 with the expectation that if I work in that version and move upwards then sp5 ought to be compatible with sp4. .

Could it be the ground textures you have used. Are any of them faulty? or need updating.

I have had this problem although I don't know what caused it. But I was able to fix it. Zoom way out, then for each baseboard with the problem, use the Surveyor Classic topology/plateau tool, set the radius to fairly small, then slightly modify the terrain.

I'll give it a go, it's about 30 miles of boards though. I am wondering if copy paste is an issue,I've used this extensively . It might be the DEM used , it had some strange issues with displaying its textures when I first opened it but I only used the dem in one section . I will delete all the transdem textures and see if this provides a solution.

 

[dangavel]

Just to be clear , the black board issue isn't appearing in cdps i saved a few weeks ago, but so far none of the copies of the route will display correctly in sp5 . All refuse to display correctly in sp5, even if they appear to be ok in sp4

Make sure you have the latest TransDEM textures installed, or are not opened for editing.

I am wondering of the original DEM is the isue, Ive been trying various versions of the route in SP5 , so far i have to go back to mid May, the DEM extension to Gunnison displays correctly in the latest version so it would appear not to be the transdem textures. . After that things get rather strange.

this is probably the strangest thing, where i have copied and pasted areas, i get the imprint of the cut and pasted area when I move about, , it usually resolves, painting over the area does cover this up , but on moving, it returns and the empty patches are never resolved, they appear and disappear depending on the viewpoint. it surely is related to textures, but I cannot find any that are open for editing or are faulty.

That's definitely a symptom of corrupted textures. Checking textures is easy. Pick another one, it doesn't matter which one, and replace the texture in that area. If the problem goes away, then that's the problem.

The problem gets WORSE, if i paint any texture over existing textures the existing texture disappears.Doesn't matter what texture it is either. Bulk replacements do the same thing Also, all the assets are freshly downloaded from the DLS, as I wanted to start all over with a new clean database so in theory none of them should be corrupt. .

I opened a more recent verison of the route, just after i did another RD Extended, at first, it appeared ok, I even thought it had possibly fixed the issue then, large sections of rendered route just disappeared, but its not consistent,, its all over the place, and as i move around other sections appear and disappear, seemingly at random. all of this is within the section i build by hand, so its nothing to do with the DEM , again, if i attempt to paint, it removes the existing texture and leaves empty space.

I've had this problem in the past on a route I've been working on for years.
Was caused by some sort of corruption in textures. In my case I was able to click on these areas using the get function and if it was a texture swap it out in bulk
If it wasn't I think I copied the grid texture over it and then the terrain texture over that again.
I eventually managed to clean it up but am still not sure what originally caused it. But as you said one minute it was fine the next I went in that's what it looked like

what is strange is that i have freshly downloaded ALL the textures from the DLS so presumably the new ones would have overridden the old, unless the textures on the DLS contain corruption and if i attempt any texture replacement it simply removes the original texture and leaves more blank space.

 

[big_b]

All my textures were from the DLS as well. Not sure If I kept the original textures or replaced them with others

I have found merging a corrupted route into a single baseboard route, not the other way around, sometimes fixes issues like this. It's as if the texture tables are reset. Remember, the grid is a texture too and this may clear up the texture problem by using the grid from the small single baseboard route.

I'll give it a try, what texture would you recommend to use for the single board , just the grid?

 

[dangavel]

all that achieved was the end of the route ( much of which is below sea level due to the original dem being lowered so much) , is now an inland sea and i cant adjust the water height. However on the plus side the terrain looks ok under the water. Any ideas of how i can get the water to lower ? should i try again and make the water level lower in both route and merge beforehand ?
