Hello, 

   I'm rather new to modding KSP and Unity in general. I am attempting to add fog and clouds to KSP and I have really no clue where to begin. I've searched Google high and low as well as the forums and all I could find is incomplete code snippets so small that they really don't help much. If someone has the time and knowledge, would you lend me a hand. Below is my code so far. I think I am on the right track with making a gameobject, assigning it's .maintexture to be my texture I choose, adding a mesh, creating vertices, triangles, etc. but I really have no idea if this is correct and if it is, where do I go now. 

 

using System;
using System.IO;
using System.Collections;

using UnityEngine;
using KSP;

namespace Clouds
{
    public class Clouds_Main : MonoBehaviour
    {
        bool debug_output = false;
        Texture2D white_clouds = null, storm_clouds = null;
        private float lastFixedUpdate = 0.0f, logInterval = 2.5f;

        Mesh light_cloud_mesh = new Mesh();
        Mesh dark_cloud_mesh = new Mesh();

        public Material light_cloud_material;
        public Material dark_cloud_material;

        GameObject dark_cloud_gameObject;
        GameObject light_cloud_gameObject;



        /* Caution: as it says here: http://docs.unity3d.com/Documentation/ScriptReference/MonoBehaviour.Awake.html,
         use the Awake() method instead of the constructor for initializing data because Unity uses
        Serialization a lot. */   

        /* Called after the scene is loaded. */
        void Awake()
        {
            if (white_clouds == null)
                white_clouds = LoadPNG(@"C:\Program Files (x86)\Steam\SteamApps\common\Kerbal Space Program\GameData\Wind Mod\S_Cloud4.png"); // Load the S_Cloud4.png Icon image into memory
            if (storm_clouds == null)
                storm_clouds = LoadPNG(@"C:\Program Files (x86)\Steam\SteamApps\common\Kerbal Space Program\GameData\Wind Mod\D_Cloud1.png"); // Load the D_Cloud1.png Icon image into memory

            light_cloud_material.SetTexture(0, white_clouds);
            dark_cloud_material.SetTexture(1, storm_clouds);

        }

        /* Called next. */
        void Start()
        {
            dark_cloud_gameObject.AddComponent<MeshRenderer>().material.mainTexture = dark_cloud_material.GetTexture(1);
            dark_cloud_mesh = dark_cloud_gameObject.AddComponent<MeshFilter>().mesh;
            dark_cloud_mesh.Clear();
            dark_cloud_mesh.vertices = new Vector3[] { new Vector3(-0.5f, 0, -0.5f), new Vector3(0.5f, 0, -0.5f), new Vector3(0.5f, 0, 0.5f), new Vector3(-0.5f, 0, 0.5f) };
            dark_cloud_mesh.uv = new Vector2[] { new Vector2(0, 0), new Vector2(0, 1), new Vector2(1, 1), new Vector2(1, 0) };
            dark_cloud_mesh.triangles = new int[] { 0, 1, 2, 2, 3, 0 };


            light_cloud_gameObject.AddComponent<MeshRenderer>().material.mainTexture = light_cloud_material.GetTexture(0);
            light_cloud_mesh = light_cloud_gameObject.AddComponent<MeshFilter>().mesh;
            light_cloud_mesh.Clear();
            light_cloud_mesh.vertices = new Vector3[] { new Vector3(-0.5f, 0, -0.5f), new Vector3(0.5f, 0, -0.5f), new Vector3(0.5f, 0, 0.5f), new Vector3(-0.5f, 0, 0.5f) };
            light_cloud_mesh.uv = new Vector2[] { new Vector2(0, 0), new Vector2(0, 1), new Vector2(1, 1), new Vector2(1, 0) };
            light_cloud_mesh.triangles = new int[] { 0, 1, 2, 2, 3, 0 };



        }

        /*  Called every frame */
        void Update()
        { 
        
        
        }

        /* Called at a fixed time interval determined by the physics time step. */
        void FixedUpdate()
        {
            if ((Time.time - lastFixedUpdate) > logInterval)
            {

            }
        }

        /* Called when the game is leaving the scene (or exiting). Perform any clean up work here. */
        void OnDestroy()
        { }


        Texture2D LoadPNG(string filePath) // Converts a .png image into a BYTE array that Unity needs in order to display as a GUI image
        {
            Texture2D temp_texture = null; // Ensure the texture is always reset
            byte[] fileData;

            if (File.Exists(filePath))
            {
                fileData = File.ReadAllBytes(filePath);
                temp_texture = new Texture2D(2, 2);
                temp_texture.LoadImage(fileData); //..this will auto-resize the texture dimensions.
            }
            else
            {
                if (debug_output)
                    Debug.Log("[WIND MOD : Gui Draw] Icon file does not exist in location: " + filePath);
            }
            return temp_texture;
        }
    }
}

I would greatly appreciate any help you can give. Thanks in advance.
