UV Set

UV Set is a powerful object for defining UV coordinates and material attributes for subsets of SDS objects. The power stems from the fact that the UV set object is derived from the SDS object itself. Many of the tools available for editing SDS objects are now also available for UV editing.

Creating UV Set objects

There are two ways of creating UV set objects:

1. Select an SDS object in the object edit mode and apply the UV Set tool with the Cubic UV Set option. This creates six UV-set objects representing front, back, up, down etc. directions.

2. Switch the SDS object into the edit mode, select faces and click the UV Set tool with the Selected faces option. This creates a single UV set of the selected faces. In this case, the UV coordinates for UV set vertices are fetched from the UV coordinates channel of the SDS object.

Of course, you can use edit/copy-paste and duplicate tools to create new UV sets from existing UV set objects.

UV set objects are created as child objects to the SDS object.

Surface division into UV areas and their texturing is managed efficiently using the select window

Any number of material mapping objects (parallel, spherical etc.) can be applied to an UV set objects to texture the actual SDS model. UV set also supports the direct texture definition in the property window's Col tab, as well as vertex channels, which now can be assigned memory efficiently only to sub areas of the SDS mesh.

Because the UV set object is SDS based, many SDS specific modeling tools can be used for editing. You can delete faces from the UV set, add new faces to it, join faces, unwrap and so on. All these tools are instantly available in the control bar as soon as you select an UV set.

UV editing tool set

In addition to the standard SDS editing tool set, there are also some UV set specific tools:

UV Set to Face Material

Converts selected UV sets to face materials of the parent SDS object. UV Set object's child mapping objects define the face material names. The UV values for the face materials are taken from the UV Sets. With this tool, you can convert the hierarchical UV set based texturing into a simpler form for exporting purposes.


This tool can be used for connecting two separate topological face groups into one.

From View

This tool takes the current view projection and uses it to set the UV coordinates of the selected faces of the UV set. Select some faces, navigate on the view window and click the tool. Simple and quick.
