Simple problem driving me crazy - applying and image to a cube

Hey guys,

Check this out: http://i.imgur.com/bfwTJNK.jpg

It’s the default cube, and a simple plane. I applied a concrete texture through a diffuse node, but I nothing renders. I carried on building the texture, add the different maps, and still nothing. Subdivided and nothing.

I literally just want to put a texture on a plane but it’s not working. What am I missing? Is it to do with UVs?

Thank youuntitled.blend (1010 KB)

By default textures are mapped to the object UVs. Your cube does not have any UVs.
Option 1 - UV unwrap the object
Option 2 - Connect a Texture Coordinate node to the texture node selecting the type of coordinates you want to use instead

Well shucks, I pressed unwrap and it works. Guess it was UV’s.

Thanks for the tip about the coordinate node. One more question, how do I get the UV to match the shape of the plane? My UV is sqaure but the plain i want to apply the texture to is more of a rectangle.
