Properties: Texture Mapping
Displays the mapping channels attached to an object and the properties of the texture mapping associated with these channels.
Texture mapping is set of parameters that describe how a bitmap texture should be applied to an object.
Types of texture mapping available include: uv (default), planar, spherical, cylindrical (including capped cylinders), box, and scaleable surface mapping. The texture mapping can scale the parameterization, offset the mapping, rotate it, and so on.
A mapping channel holds a set of texture mapping parameters. Each mapping channel is identified by a number. An object can have any number of channels and thus hold any number of different types of texture mapping. Bitmap textures in materials can optionally be assigned a channel number. When they are applied to an object, the bitmap is applied using the matching channel number on the object. Bitmap texture channels default to channel 1. If an object has no corresponding channel, uv surface mapping is used to map the texture.
Options
Show advanced UI

All textures are applied to objects using uv-surface mapping, which stretches the texture around the object depending on how the object was built.

General
Name
Projection
Surface
Specifies surface mapping.
Planar
Specifies planar mapping.
Box
Specifies box mapping
Single
Specifies that the entire texture will be mapped over each independent space.
Divided
Specifies that distinct regions of the texture will be used for each space, matching parts of the mapped object to the six independent texture spaces.
Spherical
Specifies spherical mapping.
Cylindrical
Specifies cylindrical mapping.
Single
Specifies that the entire texture will be mapped over each independent space.
Divided
Specifies that distinct regions of the texture will be used for each space.
Capped Cylindrical
Specifies capped cylindrical mapping.
Single
Specifies that the entire texture will be mapped over each independent space.
Divided
Specifies that distinct regions of the texture will be used for each space. matching parts of the mapped object to the three independent texture spaces.

Size

Equalize
Sets the size of the mapping widget to the same in each direction - the average of the previous values. This is useful for turning spherical maps that have become ellipsoids back into spheres and so on.
Size to object
Sets the position and size of the mapping widget to the size of the bounding box of selected objects.

Packs the mesh textures of meshes of the selected objects.
Steps:
Select objects.
When polysurfaces are meshed, the packed texture coordinates are created. A packed texture is a partition of the unit square into disjoint sub-rectangles so that one bitmap can be used to apply independent textures to each face of the polysurface.
The PackTextures command will pack the mesh textures of every mesh and render mesh in the selection set. If more than one object is selected, the packing "spreads" the texture over all the objects. The UnpackTextures command returns every mesh and render mesh in the selection set to the unpacked state.
These commands are generally for paint program plug-in programmers.

Notes
This command is for the simplification of data transfer between Rhino and OBJ MTL file export.
You must use an existing folder for this command to work properly. If you have already saved your model or have opened an existing model, the model's folder will be used as the default, otherwise you must select a folder.
This command will not work unless the plug-in is loaded. See Options, Plugin page.
