How to apply floor textures:
Make sure to use a Native Wood Panel atom from the + button on the UI
You can also use textures like this for most of the Native atoms, like walls, cubes, cylinders, slate, etc...
Then open the new Wood Panel atom and go to its Materials Tab, then the Textures sub tab on the far upper right.
You then need to set each of the textures for Diffuse, Specular, Gloss, and Normal Map (put the Normal in the BumpMap section.
You can adjust the color tinting, and lighting response colors on the Params tab.
Also, if you're using a native atom other than a WoodPanel, like a Slate or a Wall, my resource will not show up in the addonpackages list on the left side. You will have to browse the directories in the VaM interface to get to ../VaM/Addonpackages/.. then locate my package in the main browser window. VaM will only show packages that contain textures that are directory structured for that specific type of atom. There's no way to package textures to be as easily available for all of the different types of atoms, like Cubes, or Slates, or Walls.
