Making great progress on my layout and... this. I had a gravel texture on either side of my track, and it was working nicely, and gave me the look I was after. I opened it up to work on the route one day, and all the gravel turned to a featureless, bright, white. You can see from the tool tip that the system thinks it's gravel, but it won't display properly. None of the other textures are affected, and if I try and apply this gravel elsewhere it shows as white. I haven't been doing this in sessions, so... can anyone shed on what happened, and how to correct this? I have a LOT of hours invested in this layout and it would really irritate to have scrap it.
