Upon opening my scene, I receive over 1500 lines that say something similiar to:

CODE  
// Warning: line 0: Unrecognized node type for node 'mahdad\_FaceRig\_06\_mahdad\_FaceRig\_04\_mahdad\_FaceRig\_03\_rolling\_lips\_Dirtmap11'; preserving node information during this session. //

If anyone could shed some light on how to rid my scene of said offending nodes, I would be much appreciated.

I have tried "delete unused nodes" in the hyper shader, but it didnt work.

you need to delete UNKNOWN nodes...

delete `ls -type "unknown" -type "unknownDag"`;
