Why is the Displace modifier moving my mesh instead of moving the geometry? When I am using the Displace modifier, my whole mesh moves up or down on the Z axis, but the mesh isn't actually displaced.



I am trying to use an image to displace the geometry of the mesh. But the geometry is staying flat. What am I not seeing?

Blend:
Go to your textures tab, select the drop down called "Image Texture" and select under Modifiers "Displace"



In the new tab select the button called "Open" under image and select your desired image.



There, should be fine now.
