Set a named selection in subobject level. Possible ?

[Bobo]

Hello,

I try to set a named selection when I m in subobject level ( with maxscript of course :) ).
I don't want to stock the selection in memory (I know how to do that), I want create a named selection who appears in the combobox, and that the user can select.

It seems impossible. The only thing I found about the subobject level selection in the maxscript help is : max rns

Anyone know if it's possible ?

Thanks :)

It is not too obvious, but you can! :)

Take a look at the following chapters in the MAXscript Reference:

"VertexSelection Values"
"EdgeSelection Values"
"FaceSelection Values"

As you can see, Sub-Object Named Selection sets are handled by a separate system (as they are stored locally in the object and not globally as the object-level Named Selection Sets described in "SelectionSetArray Values")

You will also notice that the array of sub-selections is read-only.
This is not a problem though, as the method appendSubSelSet described in the "Main Toolbar" chapter lets you add a new SubSelectionSet name to the drop-down list!
The new name will NOT contain any selection though - if you have created a named sub-selection set called "Test1" using

appendSubSelSet "Test1"

while in Modify panel, Vertes SO mode, asking for

$.Verts["Test1"]

will return undefined.

BUT you can add your own selection to the new entry, either an explicit one, or the current selection from the scene:

$.Verts["Test1"] = #{1..50} --add vertices 1 to 50 using explicit bitArray
$.Verts["Test1"] = $.SelectedVerts --add the currently selected vertices

The same applies to Edges and Faces. It works in EPoly and EMesh sub-object modes.
NOTE that you *must* be in the Modify panel and in the correct SO mode to get correct results... Also note that adding a new entry to the drop-down list does not make the entry the active one, it just appears at the end of the list...

Hope this helps!

Cheers,
Bobo

YES ! Work perfectly !
Now... everything is possible :buttrock:
And... nothing can stop us :scream:

Just remember that the named selection sets do not survive topology changes. Not the last time I checked at least. Meaning if you do for example a tesselation somewhere you will loose all of them.
