Doc are you talking about line 16 in the .lxs

 

  "string filename" ["C:/Users/Rick/Desktop/MayaDesk/MayaDeskImage"]

 

Change to:

 

  "string filename" ["MayaDesk/MayaDeskImage"]

 

or maybe just

 

  "string filename" ["MayaDesk"]

 

the material file is all compiled into:

 

MayaDesk.lxm

 

?
