I was going to say, I've been 3d printing the shadow tiles and the rock out crops as prizes for our local tournaments. They really arent that crazy to print and the files are free on thingiverse. A very thin coat of krylon or rustoleum grey spray paint followed with a light grey paint on top of the tiles would likely be very easy to do to convert some ROTV tiles into a dungeon set along with the 3d printed shadow tiles and rock out crops. Looks like I found another project to do.
