Help- Trying to Export FBX with Textures

Hi,

so like the title says, im trying to export a large model to fbx with textures. I saw other people say I need to just check the box for embed media but that doesn't appear to work by itself. (the model was simply exported from a revit model, so there wasn't any work on my part past that). Ultimately I want the model in unity, with all textures. Whats strange is I can see the model with what appears to be the textures, but in the inspector, and when dragged into scene in unity, it shows up with just blank materials Seen here: http://imgur.com/a/W1JVQ . Any help is appreciated!
