I'm wondering though is it missing?
What was the original road you used?
It could be a bad spline that's doing this which I've seen occur in the past. The spline is older and not rendering properly, but loads without errors. If you can select it, meaning get the asset, you can replace it using the replace assets utility.
If you can't get it, you can always look in T:ANE and find it in TRS19, select it and do the replace assets thing.
If it is the white spline asset, you can change that to any track you want in your route. Here's the secret in making that happen.
The dashed white lines isn't "a missing asset" - it's the asset that Trainz turns to when it can't find the asset it is supposed to draw there. These white lines are, in themselves, an asset. You can find this asset in CM. It's called "Missing spline", and it's by Rob. Open it for edit. Change the KUID from <kuid:523:1124> to <kuid2:523:1124:1>, and remove the whole privileges container (containing the line "permit-listing 0") Then install that asset as if it were a new asset - e.g. drag the folder from windows explorer back onto the CM interface. Once it's installed, revert the original one (you can't commit changes to it as it's a built-in asset). Result: The dashed white lines now show up in the menu, and can be selected just like any other track spline. You could lay some down if you wanted. More to the point, you can now use the 'replace items' tool to change them to any track spline you have installed...
I will add this. When you install the folder, use the install content option. This will save so much time. Also don't panic when the creator is shown as AURAN. I hope this helps some one.
Notes:
<kuid2:523:1124:1> ==== Update from <kuid2:523:1124:2> to <kuid2:523:1124:3> for T:ANE. All other procedures apply.
Need to change .texture file using PEV's Images2TGA.
