This chapter explains the Planar and Perspective UV Mapping Mode of the Preview which allows you to assign a UV map directly in Pandoras Box. For other topics regarding the Preview tab please see the introductory chapter. The next chapter covers general mapping questions and is of special interest for mapping beginners.

Per default, a newly created Mesh in Pandoras Box has a 1:1 map meaning that any (existing) deformation in the Mesh also deforms the UV source.

Pandoras Box offers two techniques to apply a new UV map to a Mesh or an object. There is the planar mapping and the perspective mapping for which you can choose the point of view. With both mappings you can "print" the texture on a 2D or 3D Mesh again without taking existing deformation into account.

Before you get started with the UV mapping, assign a texture and an Editable Mesh to a Layer. To create an Editable Mesh, right-click in the Project tab and choose "Add Editable Mesh". If you need more than one Surface, right-click on the Editable Mesh and choose "Add Surface" adjust the size using the Surface Inspector or the Mesh Editing Mode.
In case you like to work with an imported object, simply right-click it and choose "Create Editable Mesh from Mesh". Alternatively you can drag it on a newly created Editable Mesh object as depicted to the left. Afterwards you can remove the "Surface" that was added per default.

Tools for the Mapping Modes

Most buttons are also part of the Mesh Editing Mode, please see this chapter for an explanation. The buttons starting with the stamp icon are explained in the example below.
For the Perspective UV Mapping Mode there is an additional drop-down menu to choose and reset a Reference Layer.

Planar UV Mapping Example

hmtoggle_arrow1 This example shows how the planar UV mapping works, click to open and close it. You can click on the images to enlarge them.

You can follow this example with any Editable Meshes. For now, it should be fine to program in a normal preview but later on you might want to switch to the maximized preview preview_maximize-preview-icon. This button can be found on the left site at the bottom and toggles your Preview tab to a fullscreen window. All tools are available within the Button Bar, that you can toggle with the shortcut [T]. Thus, the maximized Preview gives you the best overview, allows to see more details of the image and adjust the UV Source grids better.  You can also work with the Mesh Inspector to position, scale and rotate Meshes.

Perspective UV Mapping Example

In difference to the planar mapping, the perspective mapping allows to influence from where the texture is projected onto the Meshes.
