Terrain Mesh - texture doesnt show in enscape

Hey, I got this terrain mesh from school which I assume comes from Rhinos terrain tool (or a scan by our schools drone).
However, when I open the project in Enscape, the mesh doesn´t have it´s texture - eventhough it´s visable in rhino render view.
The texture/material applied is weird, it´s not a “PNG” or something, it´s like a material that for some reason has the texture built in. What might be the problem? I am really new to this
