How can I resize a displacement map in cycles? So I followed a texturing tutorial by Blender Guru that shows you how to add bump-, specular- and displacement maps with nodes in cycles to make your texture look more realistic. I used my own texture to make things a bit more interesting for me but it ends up being way larger than I anticipated.
This is what it looks like:

This is the size that I'd like (but with a displacement map for added realism):

Now I know how to change the size of my image textures for the basic texture and the bump- and specular maps - via changing the values in the textures' mapping-section

but when it comes to the displacement map

there is no such mapping-section there, just an image mapping-section which isn't helpful regarding the size of the texture.

If anyone knows how to deal with this, I'd greatly appreciate your help.
If you are using the UV (also default) texture coordinates mode (with Point or Vector mapping), you can use the Crop Maximum XY values to scale the Displacement Texture up and down with the same values you used for Scale on the colour texture.
