Not showing texture in export with path tracer

Hi everyone, I have a small problem in TM. I’m not very experienced with TM, so I don’t know how to solve it, and I currently need help ASAP since I have to submit it to school in a few days.

I have a base map inserted in TM in DAE format, and it has a texture on it. However, when I run the export with the path tracer enabled, the file suddenly loses its texture and appears white only – I have “two sided” enabled as well, but that didn’t help.
Could someone please help me? Thank you! :blush:
