Hi,
I have some problem, to read a material group with a specific ID.
I add the new group with following commands:

BaseContainer group;
group.SetLong( MATERIALGROUP_ID, 12345 );
group.SetString( MATERIALGROUP_NAME, "TEST" );
group.SetBool( MATERIALGROUP_SELECTED, TRUE);
GetActiveDocument()->MaterialGroup_Add( group );

Now, I´ve got a new material group. But if I read with the command
BaseContainer *bc = GetActiveDocument()->MaterialGroup_GetID( 12345 );
The return pointer is always NULL. But the group exist. I see it.
Has anyone an idea ...

Confirmed. The ID seems to be set to the index, rather than the value you suppy in Add().

This is by design. C4D assigns the ID. You can check which ID was assigned in the container returned by _Add().
