Once you have associated an image to a 3D object you will need to unwrap the facets of the 3D object into 2D parts that can be arranged on the image. This will allow you to 'map' which part of the image is to appear on each facet.
You can individually select facets on the 3D object, or select all of the facets.
To selcect an individual facet, click on the blue node of that facet. To select multiple individual facets, hold down the shift key and then click on each facet's blue node.
To select all of the facets drag a selection rectagle around the entire 3D object.
At this point you will want to begin arraging the 2D parts. There are two complementory methods to do this: Packing and Editing.
Packing 2D Parts
Packing is a algorythmic method of arrange a group object within a defined space. For UV Mapping, packing arranges all of the 2D parts within the area defined by the image.
To pack the 2D parts:
- Select the desired facets.
- Right click and select Packing 2D Part object(s) ...
- The 2D parts will automatically be laid out on the associated image.
- You can un-pack the parts by clicking Packing 2D Part object(s) ... again.
- If you have un-packed you can re-pack by agin clicking Packing 2D Part object(s) ... The second time you pack the arrangement will be adjusted. To get back to the original packing arrangement. un-pack and repack opnece more.
- When you are done packing right click and select Finish packing 2D Part object(s)...
