1. Loading the parallel hatch's java class is required
2. Using the GT registry event to register a tiered custom machine
3. The tiers to register the machine for Here, GT will generate items and blocks named gtceu:uhv_parallel_hatch, gtceu:uev_parallel_hatch, gtceu:uiv_parallel_hatch, and gtceu:uxv_parallel_hatch
4. Use the loaded class for creating the machines in the world
5. Specifying the multipart to use parallel hatch ability
6. The texture to use for the multipart, this example just uses the t4 texture as a placeholder You can look at gtm's assets to see the animations and textures to edit
7. You can just refer to the code in GCYMMachines.PARALLEL_HATCH here
