Displace NURBS Modifier (World Space)
 
 
 
Command entry:Select a NURBS object. Modify panel Modifier List World-Space Modifiers Displace NURBS (WSM)

The Displace NURBS world-space modifier (World Space) converts a NURBS object into a mesh. If a displacement map is applied to the object, the mesh shows the effect of the displacement map in viewports. There are two main reasons for using Displace NURBS:

Interface

The rollout for Displace NURBS lets you choose which surface approximation settings are used to produce the mesh.

Animated Displacement Map

If you use an animated displacement map on the mesh, turn on this toggle to have the NURBS Modifier correctly update the mesh as the displacement map animates.

You can apply a Displacement map using the Material Editor.

Update Mesh

Click to update the mesh if you have changed the displacement mapping and want to see the results of the change. The mesh isn't updated automatically because that could become extremely time consuming.

Viewport

Uses the tessellation that the NURBS object currently uses in viewports.

Renderer

Uses the tessellation that the NURBS object currently uses for the renderer.

Custom

Set the tessellation directly in the Tessellation Method group box.

Base Surface, Surface Edge, Displaced Surface, and Lock

These controls are the same as in the surface approximation controls for NURBS objects.

Tessellation Method group

The controls in this group are the same as the surface approximation controls for NURBS objects.

Ignore Surface Settings

When turned off, Displace NURBS uses the surface approximation settings for surface sub-objects. When turned on, Displace NURBS uses the settings in the Tessellation Method group and overrides settings for surface sub-objects. Default=off.

Auto Weld

All vertices closer than the Threshold value are automatically welded together. This can simplify the mesh geometry. It is useful to turn this on when you have increased the Merge value in order to eliminate gaps between surface edges in the approximation of the NURBS object.
