.fbm Folder is Empty

Goood Night,

I want to export a model from Revit to Unity. The direct workflow doesn't work for the textures as I tried and read a lot of times here in the forum. I'm trying to use the Revit - 3DS Max - Unity workflow and place the textures from the fbm folder. However, when I export the model from Revit to 3DS Max and then I export it to Unity, the fbm folder created by 3DS Max is empty. The folder is created but there are no textures there. I have the Embed Media checked. I receive two warning messages when I do the exportation from 3DS Max:

The plug-in has detected one or more animation controllers that cannot be directly supported. Using the Bake Animation option may better address these limitations. The following nodes are affected: -Compass001 -SunAndSky-002 -Sun002

and

The plug-in does not support the following lights. They will be exported as inactive Point lights with the Visibility value set to off:

-Sun002 -Sky002

I'm sorry I'm a newbie in these programs. Thank you for the help.
