Error

[landnrailroader]

What is this error message telling me. It happens at a certain point, going west on the Northern Montana route and it occurs whether I start 60 miles before it, or 5 before it?

Maybe a look at the complete OpenRailsLog would help.

Hi,

Information: Skipped unknown shader name Diffuse first seen in shape k:\1msts\routes\northmontana\shapes\gn_bigsandyhig h.s

Information: Skipped unknown lighting model index 0 first seen in shape k:\1msts\routes\northmontana\shapes\gn_bigsandyhig h.s

I can't identify the route download so am not able to check myself, but does the above shape file name really have a space before 'h.s'??

Cheers,
Ged

[rdayt]

I have 46 instances of gn_bigsandyhigh.s across various installs and not one has a space between g and h.
The shape's shading and lighting errors should be fixed but rarely do they cause any problems. Easy to do with SFM.
Good catch.

Randy

[landnrailroader]

It is not a downloaded route, it is one I am working on. The big Sandy High came from a collection of GN objects done by Stefan several years ago and came straight out of the library. I checked the name of the object in the shapes directory and it does not have the mentioned space before h.s In any case, the item mentioned, I have used in Lewistown and the error occurs several miles past Lewistown. I then created a new patch starting just before the error point, and it still occurs. So then I created another path starting after the error point and so far, I have run 30+ miles further with no issue. Now for what it is worth, I created the paths in Track Viewer and am running the route ini explore mode, not a finite activity. Doing this only allows one to use one route, i.e. what appears to be the first one on the list, so I only put the desired route in the path folder.

If either of you that have commented would like a private copy of this route to perhaps determine the issue, just send me a private message with your email. I use "WeTransfer" and compressed, the route should be around 750Mbt.

Jerry

[slipperman]

HI Jerry,
Thanks for the offer, but I don't have enough experience of route building to help. In this case, I just spotted the space in the file name as shown in the log file and wondered if it was relevant !

Cheers,
Ged

[landnrailroader]

I don't know but as I said, the name is correct in the shapes folder and in the .ref file.

Jerry

[slipperman]

Hi Jerry,
I accept that the file in the shapes folder has the correct name, but the problem may lie with whatever is calling for that file - possibly a World file?

I have an unreleased utility named World Files Search which may be helpful in locating specific files - please let me know if you'd like a copy.

Cheers,
Ged

[kapitaen]

Here is a corrected shape. Shader name Diffuse is now TexDiff and lighting model index 0 is now -5.
The Error has nothing to do with this shape, thousands of shapes have these errors.
Have you already set signals in this route? This could be the cause of the crash.

Jan

gn_bigsandyhigh.zip

[landnrailroader]

Kapitaen,

I have set mileposts but no signals as such. The line was dark territory except for the mainline through Harlowton, copied from the RMD-EAST route which had automatic block, and the area around Great Falls, copied from Michael Stefan's High Line route. I guess mileposts are a type of signal. This is strange though in that no errors appeared in the first 60 miles from Harlowton but then this. Then I created a path starting beyond this point and so far, after 40 miles there is no error.

After this shape was used in Lewistown, around 10 miles behind where the error occurred, it was not used again for nearly 80 miles ahead. This route has miles from zero at Harlowton to 200 at Great Falls, and 260 or so at Agawam, and then it has 3 branches, each of which is 30 miles or more in length.
I did a street grid for most of the communities but left the fleshing out to whoever wants to do it. Most bridges are included. I also put the tunnel portals in place, i.e. the right kind of portal, but since filling in the "hole" needs to be done in the same texture as the terrain, I also left that up to the "super detailer".

Going to cut in to this thread, as I have gotten OR to crap out while running an activity.
Route: ATSFCS - Clovis Sub
Activity: Clovis Switcher
As I arrive to the Power Plant where I am to drop off my cars and am passing the consist that I will have to pick up on my way out, OR craps out.
Error Log: OpenRailsLog.txt
Perhaps someone can decipher what's causing this, I'm at a loss understanding the errors.

[oper190]

Well it could have been one of two things.
1) An Action point was found to be off track on the loop, don't know if that would cause this but...
2) Being it was using a loop ( balloon ) track, I know there are known issues with them with the path crossing back in itself.

My resolution, was to split the activity into two parts. Part 1 took you to the powerplant and drop off the cars, and proceeding onto the loop where it ended. Part 2 starts on the other end of the loop and makes the return trip with pick-ups. Besides getting a red with an on coming AI train which was on a single track facing me, all went well. Thanks to being able to go into manual mode I as able to pull my train onto the wye the would head me in the wrong direction on the main line, but that allowed the AI train to proceed. I then backed up, reset switches and proceeded on the main in the right direction.

[landnrailroader]

I think that is the procedure most folks have used in the past. Whenever I release my enlarged KD Sub. route it will have a loop at the ARCO mine but in that case I intentionally put a 10m gap in the track so that a empty train has to end there, and then a loaded train starts on the other side. Since I did it with a default 10m piece anyone can reinsert it if they wish.

Jerry

[oper190]

Jerry, in my own work I've done the same, only by removing a .03m piece to create the gap. That way it's not so visual obvious but with the same result.
