fbx export with textures

Hello.
I’m trying to export a model with .fbx. It has materials. Textures are added. however when i import to max or blender again it doesnt show textures.

I have tried Pack Image option in the UV editor. I exported with path mode switched to Copy and clicked embed textures.
Still no luck.

I have looked online and somebody says assign texture to UV-Map. I dont how to do it or what it means.

Thank you for any responses.

i figured. it doesnt show textures in texture mode in blender. u have to switch to material mode.

Hi, I am facing same problem… can you maybe help me?

I have a default cube with some PBR material on it. I want to export it to FBX so for ex. Windows 3D viewer can open it with textures/materials (not only a dull grey cube).
I did try with packing blend files, path mode to copy, etc.

I think i miss the step how to change material to texture… ? any tips will be very helpful.
Have a good day
