I have a floor texture added to my material as a color. I would like to repeat the texture, make the initial texture smaller. I know I can do that by adding a Mapping Node and adding the vector to the input vector of the Texture Node. But when I attach the Mapping Node I stop seeing the texture correctly. It looks like it just scales up the texture way bigger than it should be, but when I try to scale it down (or up), I never see the texture come back. I only see different shades of the colors also appearing in the texture. Whatever parameter I change in the Mapping Node, I keep seeing shades, but never the actual texture. When I remove the Mapping Node I see the texture correctly again, so there's nothing wrong with my viewport. What am I doing wrong?
