This material is a placeholder and cannot be edited

I name materials so they will show up in the object manager in C4D but this morning when I opened a file I’ve been working on, all the materials that I haven’t yet named show this error screen when I click on the material button.

Any thoughts about what this is or how to override it?

Hi Alex- I can’t tell from your description where the error message is shown - is it a Rhino error?


Pascal -

As far as I can tell it’s a Rhino error. In the attached screen shot I’ve clicked on the Material button for draft top to change the material and then I get the error screen. This will occur for any of the layers that do not have material names.

Hmm- just a wild guess but is it a Brazil material and Rhino or some other renderer is current, something like that?


I’m not sure what causes this but I bit the bullet and removed all the materials that were generating the error screen. I have V-Ray installed - maybe that had something to do with it.
Anyways, thanks for the replies.
