I've been following this guide for making a custom arrow and although it does spawn, it does not have the correct arrow texture set as it gives me a 

Failed to load texture: minecraft:textures/entity/test_arrow.png

error and I don't understand why.

TestArrowRenderer.java

package com.nindybun.burnergun.client.entities.testArrowEntity;

import com.mojang.blaze3d.vertex.PoseStack;
import com.mojang.blaze3d.vertex.VertexConsumer;
import com.mojang.math.Matrix3f;

import net.minecraft.client.renderer.entity.EntityRendererProvider;
import net.minecraft.client.renderer.texture.OverlayTexture;
import net.minecraft.resources.ResourceLocation;
import net.minecraft.util.Mth;

public class TestArrowRenderer extends ArrowRenderer<TestArrowEntity> {
    private static final ResourceLocation TEST_ARROW_TEXTURE = new ResourceLocation("textures/entity/test_arrow.png");

    public TestArrowRenderer(EntityRendererProvider.Context context) {
        super(context);
    }

    @Override
    public ResourceLocation getTextureLocation(TestArrowEntity arrow) {
        return TEST_ARROW_TEXTURE;
    }
}

The name of the texture is also "test_arrow.png"

You need to set the modid in the resource location to be your own. Currently, it is searching for the texture in the minecraft resources.

OMG I didn't realize I was forgetting that part. Thanks for pointing that out!
