You can add noise to the displacement of a shader and it will work without uv maps, but I'm pretty sure you can't add a image to the normal, bump, or displacement and expect it to work without a map.
was affraid of that. so that means heightfields are UVd in order to project mmaps to displace DEM data?

Are you talking specifically about heightfields in Houdini? You can just load an image into a Heightfield File node, no UV prep necessary. Otherwise, arbitrary geometry would need coordinates, yes.

no def not using heightfields. im just trying to sculpt in geo using something like megascan height data or even substance maps but don't wanna worry about UVs at this stage. Labs just released a triplaner set up im looking at too.

You don't need uvs to sample texture
Any 0-1 values would do, in case you don't have anything better you can fit object or world space P from certain range to 0-1 and use that instead of uv
do you have a visual example by chance?
