    copied!<p>I have a <code>Texture2D</code> that I'm loading from the Content Pipeline. That's working fine, but as soon as I try to use <code>SetData</code> on a completely different <code>Texture2D</code> all of the textures in my game go completely black:</p> <p><img src="https://i.stack.imgur.com/yZGvy.png" alt="Normal"></p> <p><img src="https://i.stack.imgur.com/8OOP3.png" alt="Black"></p> <p>This is in my HUDMeter class, the class that I want to be just red</p> <pre><code>Texture2D colorGrad = Content.Load&lt;Texture2D&gt;(GradientAsset); Color[,] pixels = new Color[colorGrad.Width, colorGrad.Height]; Color[] pixels1D = new Color[colorGrad.Width * colorGrad.Height]; pixels = GetRedChannel(colorGrad); pixels1D = Color2DToColor1D(pixels, colorGrad.Width); System.Diagnostics.Debug.WriteLine(pixels[32,32]); Gradient = colorGrad; Gradient.SetData&lt;Color&gt;(pixels1D); </code></pre> <p>These are using Riemers tutorial</p> <pre><code>protected Color[,] GetRedChannel(Texture2D texture) { Color[,] pixels = TextureTo2DArray(texture); Color[,] output = new Color[texture.Width, texture.Height]; for (int x = 0; x &lt; texture.Width; x++) { for (int y = 0; y &lt; texture.Height; y++) { output[x,y] = new Color(pixels[x,y].G, 0, 0); } } return output; } protected Color[,] TextureTo2DArray(Texture2D texture) { Color[] colors1D = new Color[texture.Width * texture.Height]; texture.GetData(colors1D); Color[,] colors2D = new Color[texture.Width, texture.Height]; for (int x = 0; x &lt; texture.Width; x++) for (int y = 0; y &lt; texture.Height; y++) colors2D[x, y] = colors1D[x + y * texture.Width]; return colors2D; } private Color[] Color2DToColor1D (Color[,] colors, int width) { Color[] output = new Color[colors.Length]; for (int x = 0; x &lt; width; x++) { for (int y = 0; y &lt; colors.Length / width; y++) { output[x + y * width] = colors[x % width, y % (colors.Length/width)]; } } return output; } </code></pre> <p>And here is the code to draw the sprites, this works fine and is how I always draw sprites:</p> <pre><code>batch.Draw(meter.Gradient, new Vector2(X, Y), Color.White); </code></pre> <p>Update:</p> <p>I've actually found that the sprites that don't use the same file are not black. Does Texture2D.SetData&lt;>() actually change the file itself? what is the use of that?</p> <p>Update:</p> <p>I just tried to use the Alpha as well as RGB and it's working. I'm thinking that there's something wrong with one of the conversion methods.</p>
