I’ve recently found myself working in files with which
\na co-worker has used a plugin which I don’t have.
\nSaid plugin has created nodes which my version of Maya
\ndoes not recognize, so on load I get the classic error raised :<\/p>\n

\"errors\"<\/a><\/p>\n

Through dealing with this I’ve developed a solution:
\nFind and delete said nodes!….. Brutal.<\/p>\n

Now we can find these nodes using<\/p>\n

import maya.cmds as cmds\r\nunknownNodes = cmds.ls(type = 'unknown')\r\nprint unknownNodes <\/pre>\n
But if we try to delete them we get an error “#Error: Node is locked and cannot be deleted.”<\/p>\n
so we need to unlock them with:<\/p>\n
\r\nfor node in unknownNodes:\r\n    cmds.lockNode(node, lock = False)\r\n<\/pre>\n
then we can delete them with:<\/p>\n
\r\nfor node in unknownNodes:\r\n    cmds.delete(node)\r\n<\/pre>\n
No bringing it all together in one script:<\/p>\n
import maya.cmds as cmds\r\nunknownNodes = cmds.ls(type = 'unknown')\r\nfor node in unknownNodes:\r\n    print 'deleting: ' + node\r\n    cmds.lockNode(node, lock = False)\r\n    cmds.delete(node)\r\n<\/pre>\n
And there you have it! No longer shall you be plagued by errors on boot up :)<\/p>\n","protected":false},"excerpt":{"rendered":"
