Texture2D.GetPixel() returns 0.804

Hello,
So I am trying to read pixels from a texture 2d :

Code (CSharp):

1. Texture2D texture = new Texture2D(inputDimension.x, inputDimension.y);
2.             Graphics.ConvertTexture(renderTextures, texture);
3.  
4.             for(int j = 0; j < texture.width; j++)
5.             {
6.                 for(int k = 0; k < texture.height; k++)
7.                 {
8.                     Debug.Log(texture.GetPixel(j, k));
9.                 }
10.             }
11.  
12.  
13.             //mostly for debuging
14.             displayTexture = texture;
15.  
16.  

Now, in the inspector, displayTexture is the right texture, with colors and so.
But, the GetPixel line only return (0.804, 0.804, 0.804)
Where did i messed up ?

 

You have to set the RenderTexture you want to read as active (RenderTexture.active = yourRT), and then use ReadPixels to read the data.

See this for some examples and also check the manual:
https://answers.unity.com/questions/27968/getpixels-of-rendertexture.html
https://docs.unity3d.com/ScriptReference/Texture2D.ReadPixels.html

 

Right. If you have a look at the documentation of Graphics.ConvertTexture.

I haven't really used ConvertTexture (haven't even noticed when it was added) however from the documentation it seems like render textures are not supported.

 

Then how i can see the texture2D properly in the inspector ? where does it come from ?
