I have a block that has four different types and three different settings for each side. This means that this block has about 3000 different possible states. To not need to make 3000 models I am using the forge blockstate format. The problem is now that even though the blockstate is existing and its syntax is correct, the game throws MissingVariantExceptions for all possible states. To make stuff a bit easier, I am using a custom state mapper to map each of the four types to a different blockstate file. The names of the blockstate files are correct.

 

This is one of the blockstate files:

This is one of the stacktraces:

That variant is produced by my custom statemapper. I will try to see if sorting the properties in alphabetical order fixes it.

Yep, that actually fixed it. I am confused why that would fix it but it did.

Ok, that makes sense. Thanks for your help.
