100% pixel perfect Displacement map I'm not a highly skilled Blender user, so maybe it's a dumb question:
So shortly: how can I put my displacement map (a  square image) onto my plane (square too) matched perfectly?
With detailes: I'm in a middle of a project, what is 100% planned, and described mathematically, and it's going well, but now I need a displacement map, and I'm disappointed when I'm tryin to find out, how to put my perfect square map into the displacement modifier of my perfect square plane, if I want it to match perfectly. I have several ideas with displacement maps, but without this I can't really make them real.
Thank you
Did you make a UV map for your plain (plane?)?
If I understand correctly, your plane is square in the projection along the z-axis.
You could switch to top view, switch to edit mode, UV-unwrap with the option &quot;project from view (bounds)&quot;. This should line up everything neatly.
Maybe you'll have to rotate the UV map in the UV editor by some multiple of 90 degrees afterwards, but the size and relative position should match then.
This is how you set the texture coordinates to use the UVMap:

Or maybe upload your blendfile, so we can have a better look?
