Missing material reference

A material expression, output, function or command refers to an unavailable binding or operation. The affected material cannot pass checking or projection; a command targeting a missing node or field is rejected.

#Common causes

• A call argument or output points at a deleted or absent binding.
• An operation or custom function name is unknown.
• A custom function lacks a unique nonreserved name, valid input names, documentation or a nonempty body.

#Fixes

• Restore the missing declaration or reconnect the consumer with material.connect to an existing node and port.

• Correct the operation name or add the custom function definition in material.text.apply.

• Give custom functions unique names, distinct identifier inputs, documentation and a Slang body; retry commands against current node IDs.
