Sorry but I think there is problem with your code? I tried compile and run it but it keeps crushing. I tried Create's 6.0.6, 6.0.7, 6.0.8 under forge 47.4.10 and 47.4.16 but none works. I have attached an crash report so you could have a look. Everything is compiled with your code, no edit.

Hi,
I fixed some mixins that might have needed to be remap.
Can you try building the latest version?

EDIT: I tried to play with other create sub mobs then I noticed it become this:

Did you forgot to add the block model in assets?

@falsidge The result is still pretty bad. I was able to compile and start it with both Create 6.0.6 and 6.0.8, however, the visuals are broken pretty badly. I attached the video showcase and a zip containing the compiled mod for you to test. Still, thank you very much for your work!

@HastumeM did you runData before you build?
it needs to generate some assets before you can build it.

if you did it might be a weird directional thing I will try to fix it or an interaction with some mods

[HastumeM]

@falsidge Yea thank you very much, I tried your solution and it is all fixed. It can work with create and supplementary. However when I test it with another modpack it crash with a different reason. I guess I still need to investigate it further?

@HastumeM
Can you share a crash report or latest.log?
