Your model name is invalid!

Actually that was my old one, this one is the one i want to use:

//Made with Blockbench

//Paste this code into your mod.

import org.lwjgl.opengl.GL11;

import net.minecraft.client.model.ModelBase;

import net.minecraft.client.model.ModelBox;

public class splodesquatch extends ModelBase {

    public () {

        textureWidth = 64;

        textureHeight = 64;

        Body1 = new ModelRenderer(this);

        Body1.setRotationPoint(0.0F, 0.0F, 0.0F);

        setRotationAngle(Body1, 0.2618F, 0.0F, 0.0F);

        Body.addChild(Body1);

        Body1.cubeList.add(new ModelBox(Body1, 0, 0, -6.0F, -17.9496F, -2.6143F, 12, 12, 12, 0.0F, false));

        Body = new ModelRenderer(this);

        Body.setRotationPoint(0.0F, 24.0F, 0.0F);

        Body.cubeList.add(new ModelBox(Body, 30, 36, -3.0026F, -22.5F, -3.0026F, 6, 6, 6, 0.0F, false));

        Head1 = new ModelRenderer(this);

        Head1.setRotationPoint(0.0F, -3.0F, 0.0F);

        setRotationAngle(Head1, 0.0873F, 0.0F, 0.0F);

        Neck.addChild(Head1);

        Head1.cubeList.add(new ModelBox(Head1, 0, 24, -4.5026F, -9.0F, -6.0026F, 9, 9, 9, 0.0F, false));

        Head = new ModelRenderer(this);

        Head.setRotationPoint(0.0F, 1.5F, 0.0F);

        Leg1 = new ModelRenderer(this);

        Leg1.setRotationPoint(5.25F, 7.5F, -6.0F);

        Leg1.cubeList.add(new ModelBox(Leg1, 0, 42, -1.5F, 0.0F, -1.5F, 3, 17, 3, 0.0F, false));

        Leg2 = new ModelRenderer(this);

        Leg2.setRotationPoint(-5.25F, 7.5F, -6.0F);

        Leg2.cubeList.add(new ModelBox(Leg2, 0, 42, -1.5F, 0.0F, -1.5F, 3, 17, 3, 0.0F, false));

        Leg3 = new ModelRenderer(this);

        Leg3.setRotationPoint(5.25F, 13.5F, 6.0F);

        Leg4 = new ModelRenderer(this);

        Leg4.setRotationPoint(-5.25F, 13.5F, 6.0F);

        Leg4.cubeList.add(new ModelBox(Leg4, 0, 48, -1.5F, 0.0F, -1.5F, 3, 11, 3, 0.0F, false));

    }

    @Override

    public void render(Entity entity, float f, float f1, float f2, float f3, float f4, float f5) {

        Body.render(f5);

        Head.render(f5);

        Leg1.render(f5);

        Leg2.render(f5);

        Leg3.render(f5);

        Leg4.render(f5);

    }

    public void setRotationAngle(ModelRenderer modelRenderer, float x, float y, float z) {

        modelRenderer.rotateAngleX = x;

        modelRenderer.rotateAngleY = y;

        modelRenderer.rotateAngleZ = z;

    }

}

Replace

public () {

with

public splodesquatch () {

too.

Thanks! works perfectly now!

it still has the error

hey. im trying to import a model (java) and it just keeps saying "Custom mob model names cannot contain any whitespace, start with numbers, or cotain any no ASCII letters."

Klemen, i fixed the first problem myself but when i import the model, there is no error, it just doesn't appear in resources

Make sure to set a valid name of the model before exporting it to JAVA.

i was reading through this but nothing silved it for me

ty!

Np :)

I have the same problem and I tried to do all your advice to repair this problem but nothing is actually working. My filename is casque.java. Thanks for your help 

https://www.youtube.com/watch?v=g0MuAEV7zIA&list=PLAeL-oIFIEngE6jRgFYeFMfuj8WQsO3Ei&index=71&t=0s

I followed through and it still replies with "Your model name is not a valid Java name"

I have edited everything but still.
