As of 2.9+ series some work has been done, and more common image based texture maps may some times be correctly preserved, like diffuse, specular, glossiness, or the increasingly popular "PBR workflows", when simple image textures are directly connected to Principled BSDF shader nodes, but even this this shouldn't be relied upon. Save presets into reusable libraries when available, to reduce the amount of repetition. Lumion uses the names of imported materials from Revit, SketchUp, ArchiCAD, etc. doesn't do a propper exponent conversion so this is not technically As of 2.9+ the Blender manual states which setups are supported by GLTF 2.0, which include Principled BSDF and Shadeless (Unlit).

When exporting to .fbx, you can't export materials, you'll have the surface color, but not other settings such as glossiness and reflection, for textures, yes you can, but you have to use blender internal (it does not work with cycles), and make sure you don't use nodes, apply the textures, then, when in the fbx export settings, go to bottom, set path to copy, then check the box-like icon next to it, it should now embed the textures with the exported fbx file. Before exporting, create a new folder on your computer where you will save the OBJ and texture files. Last year, we discussed analysing the FBX files exported by Revit to access the texture data UV coordinates and other material and rendering information.
