I'm new to Blender and I have to figure out how to do this one thing for a project that I am working on.
I have an object, which I have unwrapped. I have an existing png with a size of 220x100 pixels, and it contains certain textures at specific pixels that I want to fit onto my texture. Is there any way I can generate a UV map with this same ratio (instead of 1:1 as it is now) and also position each of the faces at a specific pixel value so that it lines up with the existing UV map image? I have attached the point that I am at so far below.
