-## VectorTiles (HDRP)
-
-Can download a vector tile from a TMS service and
-can convert the tile to a raster for basing a terrain upon it.
-
-
-### Dependencies (GIT Pacakages)
-- utils
-- geotiff (for height on terrain)
-- vectortile (for building up from vector tile info)
-
-### Usage:
-
-
-```
-var tile = VectorTile.FromUrl( url );
-tile.ForEach( width=1024, height=1024, (x, y, feature) => 
-{
-	// x and y in pixel space starting at: [0, 0]
-	switch( feature )
-	{
-	}
-});
-
-Texture2D texture = tile.RenderToTextureSingle( width=1024, height=1024, layers );
