Blender 2.78 Unity 5.5 the correct way to retain material/textures on import?

@Zilppuri & @Kamil1064,

Through my current research, I came across a post about this topic from around 2011 (sorry, I can't find that post anymore) where someone much later casually commented (in 2014) that FBX added embedded media support into the file itself. To support this, according to this older version of blender's fbx export documentation, the fbx format does indeed store texture data in it, as well as material<->texture connection. Additionally, from the video link I posted in a comment above, Maya can do this as well. And, user David in this blender stack exchange post answers a slightly different question by saying the fbx exporter packs textures used by the model, indicating that yes FBX files exported from blender can include not just materials, but textures as well. And one more bit of evidence that FBX can include textures that get imported in another program/engine, this older post from 2014 about FBX importing into Unreal Development Kit (Unreal 3 Engine), Mitchell Stokes says "Just confirming that the Embed Texture option works with packed textures []" (in regards to exported FBX from blender into UDK with textures intact).

So, where lies the issue? Has blender's modern version of export FBX broken the embed media? Does Unity just not understand the embedded media? Is it embedding the wrong format of texture? I still say it should work, based on all this!

Check what Rendering engine you are using

Hi! To be honest, I don't know! :( I haven't had any time - since Unity 2018 came out - to do much work with fbx imports. I'll try to make time to see about this, but if someone active in 2018 could test it and post their results, that'd be awesome!

@Extrumus Does the Rendering Engine make a difference when doing the fbx export? Didn't know that... I think I'm in cycles but do you suggest to use blender render instead?

I don't have any problems importing textures and materials from blender-exported fbx files in 2018. I do a lot of import/edit/export on models I purchase too. Oh and I wanted to give a little something-something here for anyone who works with importation of fbx files into blender and doesn't have a way to multi-import. I've taken a script I found online and got it to work using a set path where the fbx files are stored. The script:

 import os
     import bpy
     import sys
     import logging
     
     vImportPath='C:/Full/Path/To/Location/Of/FBX/Files'
     bIsPath=os.path.isdir(vImportPath)
     
     if not bIsPath:
         logging.warning('invalid path')
         logging.warning(vImportPath)
         exit()
     
     vFileList = sorted(os.listdir(vImportPath))
     
     for vItem in vFileList:
         if not (vItem.endswith('.FBX') or vItem.endswith('.fbx') ):
             continue
         fullFilename = os.path.join(vImportPath, vItem)
         logging.warning('importing'+vItem)
         bpy.ops.import_scene.fbx(filepath = fullFilename)

How to use it:

In blender, open a text editor area/window. Then, paste this code in. Then, set the variable 'vImportPath' to the location where your fbx files are located. Then click the 'run script' button at the bottom. It may take a while if there are a bunch!
