The Decal properties manage object properties for the selected decals.

Decals are non-repeating textures that are applied to the surface of an object with a given projection. They are an easy-to-use way of attaching single images or similar textures to objects without going through the complexity of the texture mapping process.

Decals are textures that are placed directly on a specified area of one or more objects. Use decals to modify a limited part of an object's color.

Decals consist of a single instance of a texture, rather than being tiled as they are when used in a material.

Some uses for decals include:

Decal properties

Add decal to selected object

Places a new decal on the object.

Show/Hide Decal Widget

Turns on the decal widget to allow relocating and resizing the decal. The widget can be manipulated with Rhino commands such as Move, Rotate, Scale, and manipulated with the Gumball control.

Delete Decal

Deletes the selected decal.

Change decal order

When multiple overlapping decals are applied on a single object. The first decal in the list appears to be on top.

Decal Mapping Style

The mapping style determines how to project the decal onto the object. Use object snaps to help accurately place decals.

Planar

Use Planar mapping for mapping to flat or gently curved objects.

When using the planar mapping on a curved object, the entire texture must lie behind the surface of the object. Portions of the texture that lie in front of the surface will not be visible.


To place a planar decal

Note

Planar map properties

XYZ Position

The location of the starting corner of the planar decal widget.

Pick Position

Click to relocates the decal widget.

Transparency

Determines the visibility level of the decal map.

Direction

Sets the direction of the decal projection.

Forward / Backward

Projects the decal away from the front or back of the decal texture.


Forward projection (left) and backward projection (right).
Both

Projects the decal away from both the front and the back of the decal texture.


Projection both directions.
Texture pane

Click to create a new texture or select a different texture in the model.

Edit

Click to edit the texture properties.

UV

Use UV mapping for objects where the decal flows and stretches to fit the surface.

The decal covers the entire object, there is no control over the decal placement.

UV mapping uses the u and v parameterization of the surface to bend and stretch the texture.

UV map properties

Min

U/V: The start of the decal display range in U/V direction.

Max

U/V: The end of the decal display range in U/V direction.

U: Min=0.2, Max=0.7
V: Min=0.3, Max=0.8
Transparency

Determines the visibility level of the decal map.

Texture pane

Click to create a new texture or select a different texture in the model.

Edit

Click to edit the texture properties.

Cylindrical

Use Cylindrical mapping for placing decals onto objects that curve in one direction, such as labels on wine bottles.

The cylindrical projection maps the texture onto the cylinder with the texture's vertical axis along the cylinder's axis, and the horizontal axis around the cylinder.

To place a cylindrical decal

Cylindrical map properties

XYZ Position

The location of the bounding box center of the decal widget cylinder.

Pick Position

Click to relocates the decal widget.

Sweep angles
Start/End

Horz: The start/end angle of the decal display range in the circular direction.

Radius/Height

The radius/height of the decal widget cylinder.

Transparency

Determines the visibility level of the decal map.

Map to inside

Maps the texture to the outside (convex) or inside of the sphere or cylinder with a thickness.


Outside (left), inside (right).
Texture pane

Click to create a new texture or select a different texture in the model.

Edit

Click to edit the texture properties.

Spherical

Use Spherical mapping for placing decals onto objects that curve in two directions. The spherical projection maps the texture onto the mapping sphere with the texture's vertical axis (height), curving from pole to pole, and the horizontal axis curving around the equator.


To place a spherical decal

Spherical map properties

XYZ Position

The location of the bounding box center of the decal widget sphere.

Pick Position

Click to relocates the decal widget.

Sweep angles
Start/End

Horz: The start/end angle of the decal display range in the circular direction.

Vert: The start/end angle of the decal display range in the vertical direction.

Radius

The radius of the decal widget sphere.

Transparency

Determines the visibility level of the decal map.

Map to inside

Maps the texture to the outside (convex) or inside of the sphere or cylinder with a thickness.


Outside (left), inside (right).
Texture pane

Click to create a new texture or select a different texture in the model.
