Hello, I hope you are feeling well. You can solve it if when you export your model as FBX you activate the Copy to a single place and Reference option and save your textures in a specific location. This will save the textures as separate files. When you import the model into Blender, you just edit the materials and reload the textures into the material. The material is already created, you just have to reload the textures. However, I'm not sure if this is the best workflow, as doing this breaks the texture mapping completely and you will have to readjust it. Navisworks usually works with BIM models which come from applications like Revit. This model seems to me that it comes from some software like 3dsmax and at the time of exporting it had problems even with the location of the coordinates, since it is lying down. It will be more appropriate to adjust it from the creation software.
Excuse my English, I hope to be of help, greetings!!!
Good morning, I'm glad to hear that you find what I shared helpful. In this case, if your workflow is with Revit, everything is simplified. The solution I shared with you is for an atypical case. A character like the one you shared with us would not be a model that would be regularly worked on in Navisworks, that's why you have to do it manually. However, being a Revit model, you can save the Navisworks step. You can export directly to FBX from Revit:
However, this option also has the problem that it does not carry the textures in the model. From my own experience, in the new versions of Revit, you will have enabled in the view menu, the FBX exporter for Twin Motion and this add-on is effective to take the model with all the textures and works great with Blender. In case you don't have it installed, you can easily search it on the internet as Datasmith Exporter plugin for Revit. This is the best way to export a BIM model with textures.
I hope you find it useful, greetings!
