Black screen when launching minecraft

Before the mod was working perfectly fine, but after I updated to the newer version of mcreator, i can no longer play my mod, the mod fails to load and the screen turns black. I updated my gpu reinstalled my mcreator and did everything i thought of.

yes but that is not the issue. I got that error when i started the mod and instead of fixing it i just made a new texture and just didn't remove the old one, and the game ran fine still.

  1. java.util.concurrent.CompletionException: java.lang.IllegalArgumentException: Failed to create model for op_mod:cyn 

Seems this model is also broken

I recommend reading through the log

but why would it break now? before updating the game ran fine. I didn't change the model or anything else in the mod after updating mcreator and now suddenly the model is broken?

Also, the model being used is a built in biped, so its supposed to be working.

 klemen mentioned something once in a similar thread

"In 1.21.8, if animation references body parts your model does not contain, the game will crash"

And at the very least the log shows which model has an error so you don't have to go and check every single one hehe

it does say there is a model that cannot be created because the right leg of it doesn't exist in the model and it cannot be animated, however when i open it in blockbench (the exact same file that mcreator uses) the model has a right leg.

Then maybe try exporting it and re-importing it again. Which will mean deleting the model currently in MCreator, then importing the new one.

i replaced it and it works, but now there is another model that cannot animate right leg. The problem is that it doesn't use a custom model and just uses a biped model with a skin.

I understood the problem from the message about klemen. it turns out that I had my model made and an animation from mcreator was superimposed on it, and therefore I had a black screen, review all the animations on the entities and try again to enter the translation
