Using ModAPI in your mod

ModAPI.LoadTexture(string fullPath, FilterMode filterMode = FilterMode.Point)

using UnityEngine;
using WorldBoxModLoader;

namespace SampleMod
{
    public class Mod
    {
        public static void Main()
        {
            GameObject sampleObject = new GameObject("SampleObject");
            SpriteRenderer spriteRenderer = sampleObject.AddComponent<SpriteRenderer>();
            Texture2D texture = ModAPI.LoadTexture("texture.png");
            spriteRenderer.material.SetTexture("_NORMALMAP", texture);
        }
    }
}
