I have problem when i starts minecraft with my mod installed it freezes on loading and on loading world. I don't have anything like datagen that can slow down loading. Only thing i am afraid it's slowing down are models (for blocks). Is itr possible that complex models can slow it down? I have about 15 custom block models and about 40 models that has them like parrent. In case it is caused by models doe's someone know about something that can speed it up? Thank you
