Hi Eric Cosky, I would like also to remember that you can apply the Unfold3D plugin to a Softimage Group containing several objects, it not necessary to merge all objects in only one polymesh. The possibility to work with Groups allows for example to create UV maps of a car, without merging the wheels / the car body / the interior etc... Here is the workflow in that case : 1. Select some objects 2. Ctrl + "g" for creating a group 3. Select the group just created 4. Property > Texture Projection > Unfold 5. Modify cutting line / Modify UV coordinates by hand in the texture editor / Update Unfolding / Pin / Pack. In the order you want.
And the last case, it is when you have several objects having existent
UVProperty and you want to make modifications / packing of all of it, without
merging the objects :
1. Select the objects
2. Ctrl + "g" for group
3. Using the explorer, select the group and select also the existing
UVProperties (e.g. Texture_Projection Cylindrical XY, Texture _Projection
Spherical XY )
4. Property > Texture Projection > Unfold > Pack (TAB) > Pack
5. Modify cutting line / UV coordinates by hand in texture editor / Update
Unfolding / Pin / Pack
Regards
Nick
