Thanks for that info. I tried the script out and it makes sense, but it's not quite what I was talking about (good to learn about packing with a group though, I hadn't noticed that feature before). The repack after manual editing of UVs works as expected, but it seems that once the UVs have been packed the original texture support's transform is ignored until I delete the ClsSetValuesOp.
I just wasn't sure what the limits & expected behavior was, and I suppose it makes sense that there would be a functional disconnect from the texture support once packing had occurred. If I want to restore the UV data from the texture support then it's no big deal to just delete the ClsSetValuesOp.

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 Last case sample script: CreatePrim "Cylinder", "MeshSurface" CreatePrim "Sphere", "MeshSurface" Translate , 9.49132845941504, 0, 0, siRelative, siView, siObj, siXYZ, , , , , , , , , , 0 SelectObj "cylinder,sphere", , True ApplyShader , , , , siLetLocalMaterialsOverlap SelectObj "cylinder", , True SelectObj "sphere", , True CreateShaderFromProgID "Softimage.txt2d-image-explicit.1.0", "Sources.Materials.DefaultLib.Material1", "Image" SIConnectShaderToCnxPoint "Sources.Materials.DefaultLib.Material1.Image.out", "Sources.Materials.DefaultLib.Material1.Phong.diffuse", False SelectObj "cylinder", , True CreateShaderFromProgID "Softimage.txt2d-image-explicit.1.0", "Sources.Materials.DefaultLib.Material", "Image" SIConnectShaderToCnxPoint "Sources.Materials.DefaultLib.Material.Image.out", "Sources.Materials.DefaultLib.Material.Phong.diffuse", False SetDisplayMode "Camera", "textured" SwitchToolbar 1 CreateProjection "cylinder", siTxtCylindrical, siTxtDefaultSpherical, "Texture_Support", "Texture_Projection" SetInstanceDataValue , "Sources.Materials.DefaultLib.Material.Image.tspace_id", "Texture_Projection" SelectObj "sphere", , True CreateProjection "sphere", siTxtSpherical, siTxtDefaultSpherical, "Texture_Support", "Texture_Projection" SetInstanceDataValue , "Sources.Materials.DefaultLib.Material1.Image.tspace_id", "Texture_Projection" SelectObj "cylinder", , True SetSelFilter "SampledPoint" SelectGeometryComponents "cylinder.sample[57,60,61,64,80,81,84,85]" SelectGeometryComponents "cylinder.sample[9,12,32,33,57,60,61,64,80,81,84,85]" SelectGeometryComponents "cylinder.sample[9,12,32,33,57,60,61,64,80,81,84,85,119,122]" TranslateUVW "cylinder.sample[9,12,32,33,57,60,61,64,80,81,84,85,119,122]", "cylinder.polymsh.cls.Texture_Coordinates_AUTO.Texture_Projection", 0.317275697984523, 0.358676756756757, 0, siRelative, siUVW, False SelectObj "sphere", , True SetSelFilter "SampledPoint" SelectGeometryComponents "sphere.sample[*]" RotateUVW "sphere.sample[*]", "sphere.polymsh.cls.Texture_Coordinates_AUTO.Texture_Projection", 0, 0, -89.8125, siRelative, siUVW, 1, 0.5, 0.5 SelectObj "cylinder" ToggleSelection "sphere" CreateGroup AddToSelection "Texture_Support", , True AddToSelection "Texture_Support1", , True CreateGroup "UnfoldGroup", Array("cylinder", "sphere") UnfoldApply "cylinder.polymsh.cls.Texture_Coordinates_AUTO.Texture_Projection,sphere.pol ymsh.cls.Texture_Coordinates_AUTO.Texture_Projection,UnfoldGroup" UnfoldPackUpdate "UnfoldGroup.Unfold"
