Missing texture mk3a's

[ste2002]

Im trying to create intercity swallow versions of the wcml mk3a's. Ive got all the coach body textures in place all except what i assume is a shadow texture. Ive got the blue stripey lines between the rails under the coach bogies saying missing textures. Ive searched and wondered whether its a texture in the system folder but had no luck. Any ideas would be welcome.

Cheers
Steve

Open the geo file in RW_Tools, the materials are fairly near the top so you can reasonably quickly scan through the paths of all the textures it's referencing.
