Material Editor - assignment creates copy

While i assign materials from the _MaterialEditor, many material copys are created. eg. try this:

  • enable RenderedViewport
  • draw a box
  • type _MaterialEditor so it opens the dialog
  • create a new material, any type
  • drag & drop it on the box, material gets assigned OK
  • create another material, any type
  • right click on the material name and choose “Assign to objects”

The material gets assigned to the selected box but a material copy is created with trailing number. Note this is happening under windows but somehow related to this thread from a year ago.

Hi Clement - I am not getting copies here but materials are not assigned via ‘Assign to objects’ at all. Clearly something is broken - thanks.

Yes, that happened to me yesterday but today i was not able to repeat it. The copy creation seems to be repeatable in WIP (6.0.16061.12151, 01.03.2016).

A-a-a-and after a restart of Rhino, assigning by both ‘Assign to objects’ and drag and drop appears to work as expected. Still playing…

After reopening…over here it just creates the material copy right before the assignment, eg. when nothing is selected and it asks for the object to assign to. WIP version (6.0.16061.12151, 01.03.2016)

Hi Clement - opening a file sent by a user I can reproduce this - thanks for the report. Not sure yet if that tree layout is part of this or not… I am getting other weird (to me) behavior in that arrangement. Still poking.
Yes it seems only to happen in Tree view of the material panel.

Thanks Pascal, please also note the upper right corner in my image above, those controls are slightly too close to each other. Btw. the help button does nothing over here yet.
