I've had to delete and reinstall cubik a few times since I've been switching computers... does anyone know how to remove this error?

Here is the lightsaber in all of its glory! Man, only if sphax84 saw this for himself. (FYI, its my first model.)

yupp. Could you actually walk me through like step-by-step how you export cubik models to minecraft models? I Have honestly no idea what the mesh_atlas is, and I need to know how to export the models.

I cant export my json to minecraft without getting the pink and black texture. I'm fairly new to cubik, so help is appreciated!

my json is attatched to this post
