Model engine / blueprints

Hi Aternos , I've been trying to use the [ConxeptWorks] Model Engine Demo plugin [using spigot], but I can't upload my 3D models in the blueprints folder of the plugin, is there a way to upload my 3D models?

thank you.

thanks, but what i meant was Import the models plugins/Model Engine/blueprints from the server folders in aternos,

because if you don't allow Import, the plugin won't do much good.
