Resolved Passing light direction to a shader to render on a texture.

Hello
I have a problem I don't understand, yet another thing that use to works and suddenly stopped after refactoring...

So I'm rendering using low level call to a texture, which I update everyframe. However it seems that passing the light direction no longer update for some reason.

Code (CSharp):

1.  
2.  
3. //the update function
4.  void Update(){
5.         foreach (var scene in scenes){
6.            glight.updateLight();
7.            scene.updateLight();//TODO: only when light change, refresh
8.         }
9.  
10.  
11. //...
12.  
13.     public void updateLight(){
14.         GI.updateDirectLight(geometry);//TODO:only when change happen, this render and cache direct lighting on a texture
15.         RenderSurface.show(root, GI.returnDisplay());
16.     }
17.  
18.  
19. //function that don't update
20. public  void updateDirectLight (Mesh[] mesh){
21.         directPass.SetVector("_MainLight",globalLights.directionalLight);
22.         RenderSurface.applyShader(mesh,directlight,directPass);
23.     }
24.  
25. // what render surface does:
26. public static void applyShader(Mesh[] mesh, RenderTexture canvas, Material painter){
27.         RenderSurface.initRender(canvas, painter);
28.         RenderSurface.clear();
29.         RenderSurface.render(mesh);
30.         RenderSurface.close();
31.     }
32.  
33. //low level graphic rendering utils
34.     public  static void initRender(RenderTexture RT, Material mat){
35.         Graphics.SetRenderTarget(RT);
36.         // GL.Flush();
37.         GL.PushMatrix();
38.         GL.LoadOrtho();
39.         mat.SetPass(0);
40.     }
41.     public  static void clear(){
42.         GL.Clear(true, true, Color.black);
43.     }
44.     public  static void render(Mesh[] mesh){    
45.         //cycle//spin//run//shift//jolt//period//turn//swing//generation//phase//index
46.         //pass//sweep//loop//order//move//lap//walk//trace//tour//epoch//time//session
47.         for (int pass = 0; pass < mesh.Length; pass++)
48.         {
49.             Graphics.DrawMeshNow(mesh[pass],  Matrix4x4.identity);
50.         }
51.     }
52.     public  static void close(){
53.         GL.PopMatrix();
54.         Graphics.SetRenderTarget(null);
55.  
56.     public  static void show(GameObject frame, RenderTexture canvas){
57.         Material CanvasFrame = frame.GetComponent<MeshRenderer>().sharedMaterial;
58.         CanvasFrame.SetTexture("_MainTex", canvas);
59.     }
60.     }

I mean the code works because:
- it properly show the rendered texture, it just don't update it when I move the light and return the light direction data.
- I verified that the light is properly passed because outside of play, I move the light, then use play and again and the color has changed accordingly, so it's the update that fails. A debug.log show the light data varying. Before and after the function call.
- It used to work in the prototype spaghetti code, the code was mostly copy pasted.
- I checked Typo in case of, i'm out of options.

 

I'm trying to look at the profiler, but as far as I can tell...


I emited a log from the rendering function and it seems to be called and work fine ...

This doesn't make any sense.

 

This time I tried to preemptively not being stuck month before asking help, well I figure out that one.
