3DN-SurfaceDisplacement - Documentation

Installation

Download the "3DN-SurfaceDisplacement" .blend file and save it somewhere memorable. In Blender, go to File -> Append -> locate the .blend file -> Collections. Then selected the "3DN-SurfaceDisplacement" collection and press "append". Alternatively, you can use the same process but import the geo node group instead.

Controls

Mapping

"Geo UV Map": The UV unwrap of the object the modifier is applied to.

"Displacement TX": The displacement image or any image you want to displace the geometry

"UV Scale": Allows for UV tiling if you're using seamless textures (add "uvScale" attribute to match the texture scale in the shader editor)

"UV Rotation": 3 Axis rotation controls (add "uvRot" attribute to match the UV rotation in the shader editor)

Displacement

"Displacement Scale": Controls the scale of the displacement effect. (e.g. "0.050" will be very minor displacement whereas "4.000" will much more)

"Clamp Min/Max": Clamps the values of the image texture you're using making it possible to flatten out areas of your mesh or clamp the maximum to create a cracked looking effect.

"Edge Crease": Works in the same way as with a subdivision surface modifier.

Subdivision and Material

"Viewport Level": Subdivision as viewed in the viewport.

"Render Level": Subdivision level that's only applied during render.

"Extra Subdivision": An additional subdivision surface (can help smooth out jagged edges)

"Material": Set whatever material you want to be applied to the mesh.

Extra Notes

As mentioned earlier, if you're using a custom material you can add "uvScale" and "uvRot" attributes into the shader editor. This will link whatever scale or rotation you set in the modifier with the material.
