 I exported these models just in case I, (or anyone else) ever want's to use mesh nodes rather than the crazy nodeboxes.
 When importing into Blockbench you will find a node named "converted_out" (it will be at the top of the list, .. you want to delete that mesh as your first step.
 Then, ..good luck from there deleting ALL those unecessary faces and then UV editing.. (you are a much braver soul than me)
