Due to a large lack of passenger stock, I've been building Pullman heavyweight sleeping cars to the exact plans. The car shown here (for what it's worth) is a Six Section, three drawing room (6-3) equipped with Pullman Ice Air Conditioning.

(Image edited to reflect the completed car as shown in 3D Canvas Pro)
As you can see, I've been making good headway, but at this point have run a ground in extensive problems dealing with the model itself exporting properly with the textures (The interior texture renders right, yet the Tuscan outside texture refuses).
EDIT: Currently the model now exports properly from 3D Canvas Pro, but will not export from the Assets Editor. Each time I receive mention of error reading Either Texdiff or any of the texture .fx engines, on line 1003. Has anyone encountered this with any model of theirs? Thanks in advance
