Issue comments
For anyone else who wants to fix this problem before 2020.3,
go into your java code and press CTRL+H (on windows at least) and do this:
Find What: RendererModel
Replace With: ModelRenderer
and click replace all and import it again. If you are doing this on or after 2020.3, this bug is fixed and no longer an issue
For some reason Blockbench gets the order of the words wrong.
The code of this model uses RendererModel which only exists in 1.14.4 and will not even exist in 1.15.2 anymore. I will add compatibility for this so MCreator will fix this, but devs of the modeler you use need to fix this (use ModelRenderer instead of RendererModel as RendererModel only existed in 1.14.4 for some reason). These models also lack setRotationAngles method.
