Exporting OBJ with Textures UR5.1

Hello,
Question for the community.
I have imported a project from Twinmotion via Datasmith, getting the project in with all the textures works perfectly, but when i try to export OBJ all of the materials and textures exported are Red, please can someone tell me what i am doing wrong or advise on the process to successfully export in OBJ format to use in other design software.

Many thanks,
