Jordan -- how are you overcoming the no spec in editor problem? Are you running your scene and tweaking material instance values while the game is running? I wanted some of the DX11 bells and whistles but was forced to go DX9 to get around the spec issue. Thoughts?
There was a problem with no spec appearing in the march verison but it seems to be sorted in the april version. Your scene is looking so nice, in fact I dont think I have ever loved towels before!
