Same material and textures to two objects and they display differently

[Anonymous]

Hi All,
I am new to the python fbx sdk, I started learning from the examples (ExportScene02, ExportScene03) ,made some modifications and generated this fbx file. in the python script, I create two objects: straight line and curved line with the same materials, same textures and same properties. but these two objects display differently ( as shown in attached image). Also, Attached is the fbx file and python script (functions I used to create materials and textures: curvedTexture(), straightTexture() ). Why this happen? and how can I solve it? Thanks.

It looks like you have not defined UVs on the mesh (plane). The rendering engine is most likely map everything at (0,0)
