                <p class="desc">Another thing you can do in blender with this method is plug the alpha into the factor value of the "mix color" node.
                    <br> this <b><i>separates</i></b> the two colors in the mix node by the alpha layer, allowing for more customization and creativivty</p>

                    <p>In this example I used a copy of the model and turned it into a glass overlay by taking just the alpha, from the image, plus 2 colors</p>

                    <p class="desc">You can also split the alpha, and use one of the 2 color attributes in the mix color node to set transparency of either the alpha or other (reverse select),
                        <br> In this case I took the default cube and took some image, setting up my selection for the alpha, split the alpha (like above), than used the transparent shader to make the
                        <br> white-space, finally duplicating the cube and using a volume scatter to <i>somewhat</i> fill the inside of the cube.
