1rst. Let me present how I came to find the said result.
- Repainted the file NP24ft_parts01.TgPcDx in photoshop (a simple straight forward operation). I decided to paint each door yellow...
- Concerted NP24ft_parts01.dds to NP24ft_parts01.TgPcDx, NO problem
- fired-up the game to view the result; and...
- At one end the door is, as desired, yellow. At the other end the door is brown (why???) and not yellow as it is visible if you view the uploaded .TgPcDx
I have a possible reason, but I cannot be sure of my conclusion. Could it be a result of the initial texture mapping on the 3D-model? If so, only Stephan can confirm and
( if so, could you remap the caboose?

Any other idea or solution are welcomed.
