Datasmith - Materials cropped different fields in the same bitmap only display one texture

Material cropping in 3DS Max doesn't seem to translate well into Datasmith when they are used in the same bitmap.

This was reported and tested in 4.24.3 (CL-11590370). This was reproduced in 4.23.1 (CL-9631420), 4.25 Preview 2 (CL-12055273) 4.26 (CL-12192349)

1. Download the attached file
2. Open the UE4 Editor and create a Blank Architecture, Engineering, and Design project
3. Import the datasmith file and compare it to the screenshot or the scene in 3DS Max

Results: After export to Datasmith there is only one texture from the cropping.

Expected: All textures to appear when imported
