Houdini 20.0 Nodes Geometry nodes

UV Project geometry node

Assigns UVs by projecting them onto the surface from a set direction.

UVProject creates the UV texture attribute if it does not already exist. The attribute class (Vertices or Points) is determined by the Group Type. It is recommended that UVs be applied to vertices, since this allows fine control on polygonal geometry and the ability to fix seams at the boundary of a texture.

The best way to visualize the effects on UVs is in the UV view. To change a viewport to show UVs, click the View menu in the top right corner of a viewport and choose Set View ▸ UV viewport, or move the mouse over the view and press Space + 5.

You can also visualize UV attribute values in the 3D view using an attribute visualizer.


For closed mesh, Bezier and NURBS surfaces, projections with boundaries will result in seams. UVTexture can be used to open these surfaces automatically. Alternatively, convert the surface to polygons using a Convert operation prior to applying UVProject.

Using UV Project

  1. Select the points at the geometry level.

  2. Click the UV Project tool on the Texture tab.

  3. Choose the Projection from the drop-down menu in the parameter editor.

Plastic Wrap

You can transform, rotate, and scale the texture using the projection handles.


UV Attribute

The name of the texture coordinate attribute to create, defaulting to uv.


Subset of geometry to apply texture UV coordinates to.

Group/Attrib Type

The type of elements referenced in the Group field, and the class of UV texture attribute to use.


Type of projection geometry to use.

Inner Radius

Inner radius of the torus used in a Toroidal projection. The outer radius is always 0.5.


Transform Order

Order in which transformations occur.

Rotate Order

Order in which rotations occur.


Amount of translation along xyz axes.


Amount of rotation about xyz axes.


Non-uniform scaling along xyz axes.


Local pivot point for transformations.



Specify how to initialize the transform when the Initialize button is used.


Automatically fit the projection geometry to the group’s bounding box.

U Range

The location of the left and right edges, respectively, of the texture on the projection geometry.

V Range

The location of the bottom and top edges, respectively, of the texture on the projection geometry.


Rotates texture coordinates about the point (0.5, 0.5) in UV texture space.

Fix Boundary Seams

Makes sure the texture wraps around correctly. This only works for vertex UV attributes.

Fix Poles

Use the UV coordinates of neighboring vertices to improve undefined projections at the poles of the projection geometry. (For example, the north and south poles of the Polar projection).

Pole Radius

The distance from the exact pole within which a vertex is treated as being in that pole.
