Can't Run Client And Need Help 2025.3

(I am pretty sure no one has had this problem)

When I added a java file for a model from blockbench this is what it showed:

I think the problem might be the name of some bone into your model, do you have a bone or something named with just one letter? or with differente simbols numbers or spaces?

I have bones with underscores, but I have done that in the past and it has been fine, so I don't think that's it.

Thanks for the help though.

This error is happening because of the name of the model / constructor that Blockbench exported, and how Java works together with MCreator.

In Java, the constructor name must be exactly the same as the class name, and it cannot contain spaces.

Your error says:

ModelAbyssal_Behemoth.java:38: error: cannot find symbol
public Abyssal Behemoth(ModelPart root) {
^
symbol: class Abyssal
location: class ModelAbyssal_Behemoth<T>

ModelAbyssal_Behemoth.java:38: error: cannot find symbol public Abyssal Behemoth(ModelPart root) { ^ symbol: class Abyssal location: class ModelAbyssal_Behemoth<T>

This means Blockbench exported something like:

public Abyssal Behemoth(ModelPart root) { // ... }

Java reads that as:

Abyssal = a class/type name (which does NOT exist),
Behemoth = the constructor name.

So it crashes with cannot find symbol: class Abyssal.

Make sure to export your Blockbench model without spaces and using the same method. Do the same with the model parts, such as the body, bones, and anything else found in the model. Then, export it as ModelAbyssal_Behemoth.java, making sure to use the same name when exporting to MCreator. Only use a different name for the living entities section, where you can enter a custom name.

This error can occurs when java dont get something, java is really crazy, so it can occur sometimes, xd.

I'm a bit confused here, IDK if this will help but here is the code inside the java model when I exported it from blockbench.

Maybe I missed something, but I don't think I did.

// Made with Blockbench 5.0.4
// Exported for Minecraft version 1.17 or later with Mojang mappings
// Paste this class into your mod and generate all required imports

    // This layer location should be baked with EntityRendererProvider.Context in the entity renderer and passed into this model's constructor
