Custom Java model turning invisible.

Did you use Blockbench?

Did you make a valid texture?

Did you put any of the cubes in a group? (in the modeler)

I'm having the same problem.

I did use Blockbench, I did make a texture, and I did not put any of the cubes in a group.

I imported the model and the texture into MCreator, and I used them both when creating the entity.

The model has 5 cubes by the way.

Aha! I know the problem! I had it too. For some reason, starting with version 3.5.0, all cubes in the model has to be in a group.

And I would put and the groups in one big group, just in case. Also, without any groups, your model won’t animate.

Thank you that worked.
