Tf2 model compile problem

Whenever I try re-compiling a tf2 model in guistudiomdl, it aborts the process and spits out this error:

\mdldecompiler.qc(42): - can't find eyeball texture "eyeball_r" on model

Is there a way to fix this?

Yes there are ways, sometimes, depends on the model from what I gather.
A look at the .qc would help. Especially would like to see the eye texture info the qc. file is pointing too.
