Summary

Sometimes the user wants to use nodes to work with multiple materials.
This package makes it possible to know about the number of materials without the use of statistics or accumulation.

Currently only mesh is supported, but may be expanded in the future if other components have materials.

Other domains seem to have extremely curtailed materials support ...

33 ↗	(On Diff #52447)	Need to explicitly trim the length of the string to the limit.

Correction:
Now there are no problems when copying materials.
Name string is truncated for search

Resource ownership. Today I realized that this is a fairly common problem.
The materials will only be owned if the user selects them in the field.
If the material was obtained in some other way, then it will not be saved.
I thought I could do ownership. But for this I need to be able to refuse them,
otherwise with each update I will simply produce users.
You need to decide whether geometry nodes should
set ownership of the resources that are computed in
them. Or is it solely the task of the user.
