Cubik Studio

I want to use one of my 3d models for the 1.13 snapshots but no matter what I do it always just turns into a black and purple cube.

Can anyone help?

Yes, it does support MC1.13 as nothing changed in the modelling system.

If you're having issues with a model you should check your Minecraft log files to see if it tells you the error.
