Overview
This article contains information related to the Missing, Disconnected, Orphaned, and Self-duplicating materials in Rhino. It provides guidance on what steps to take with affected files.
Issue Description
Issues related to the Missing, Disconnected, Orphaned, and Self-duplicating materials in Rhino have been recognized by the Chaos team to appear randomly for a number of users in the past. Some of the identified reasons causing those issues are the following:
- The project has been created with a Rhino 7 version older than SR 13/15 or it contains imported content that was created using this version range;
- Material duplication and loss of data due to being saved without serialized plugin data;
- Material duplication and loss of data due to a project being opened, edited, or saved when the V-Ray for Rhino plugin is not installed or disabled;
- Rhino project loading before V-Ray is fully initialized;
- Material duplication and loss of data related to specifics on the user side.
What to do with a file that has already encountered the issue?
If the file has already been affected and the materials are missing from the Asset Editor we recommend testing a few steps. Firstly, try to reopen the file by starting Rhino, making sure V-Ray is properly loaded, and then using the “Open” command line.
Go back to the previously saved version of the file and check if the same issue reoccurs (for example, if the current file is Projectname_10, go back to Projectname_09). If the problem reoccurs, go back to the serialized saved version where the issue is not present. If the file is not “Saved as” and serialized, search for the Autosave file in the Recycle bin.
If there is no serialized old file or autosave file, do not copy and paste/import the project or any parts or assets from this project to another, as this may cause issues and unpredictable behavior with the new project as well.
