NormalizedByte4 Texture2D gives different results from XNA

[monogany]

I managed to get the shader to work. I built the texture in XNA in the Vector4 format instead of the NormalizedByte4 format, and everything became better.

Now my only problem is that MonoGame has an issue that prevents the SpritePacker Copy from working with Vector4 bitmaps. I created a separate post for that:

PixelBitmapContent<Vector4>.Copy works in XNA, but MonoGame throws exception

The following code works in XNA but MonoGame throws an exception: System.InvalidOperationException: Could not copy between Vector4 and Vector4 PixelBitmapContent<Vector4> source, output;` (...) PixelBitmapContent<Vector4>.Copy(source, new Rectangle(0, 0, w, h), output, new Rectangle(x + 1, y + 1, w, h)); This is the framework code that throws the exception: /// <summary> /// Copies one bitmap into another. /// The destination bitma…

For now, my workaround will be to compile the spritesheet in my old XNA project and transfer the .xnb file to MonoGame.
