Hello ! I don't really know if I should set this as bug report or support request,but I post it as support request.
I made a model using the Blockbench brand new java exporter for entity model, but everytime I get a strange error.
I guess it's like when Tabula first appeared, you will need to code the support of the model coming from this modeller, but it's still a strange error.
I will attach in that post the model (don't steal)
