I have to images:
Texture_Opacity.jpg and Texture_BaseColor.jpg
and i want combine them into
Texture_Albedo.png
Texture_Albedo.Red = Texture_BaseColor.Red
Texture_Albedo.Green = Texture_BaseColor.Green
Texture_Albedo.Blue = Texture_BaseColor.Blue
Texture_Albedo.Alpha = Texture_Opacity.Red

Can you share your images so I can better understand what you are trying to do?

You can do this:

using var baseColor = new MagickImage("Texture_BaseColor.jpg");
using var opacity = new MagickImage("Texture_Opacity.jpg");
baseColor.Composite(opacity, CompositeOperator.CopyAlpha);
baseColor.Write("Texture_Albedo.png");
