Block model types

blockModelType values are available through polymer and limited in number, since they re-use block-states that are visually the same on the client.

The following options are availble, with their amount:

See the polymer documentation for more infos about the properties of the block model types

As of filament 0.16 it is possible to flag the block as virtual, to allow for an unlimited amount of block states. See Blocks for details.

When choosing blocks that break instantly on the client, like plant_block or tripwire_block for example, the destroyTime property in the block config has to be 0 as well.

You can map the blockModelType field of block configs to blockstates, this allows you to change the hitbox of the block depending on the block-state.

In some cases, for example when using the waterloggable behaviour, you might want to specify the waterlogged state for your custom block.
