This is a section of the tutorial “Making an Accessory – Female Sunglasses“. See the entire article here.

To create your own sunglasses, we have supplied you with 3 texture options:

  • Glasses Frame

You are going to change each texture to get a cool pair of sunglasses.

  ○ Glasses Frame Texture

  • To open the “Glasses Frame” texture, go to the top menu and click on File ➞ Open.
  • Go to the folder where you have saved the texture, select it, and click Open.

The easiest way to change the color of the glasses frame is to make a new layer.

Layers

Images stacked on top of each other.

To do so, look for the toolbar on the right bottom corner of the screen and click on the Create a new layer button .

A new window opens to set the attributes of the layer.

Click OK.

You can use the Zoom Tool to magnify or reduce the view of the texture.

To ensure you see everything correctly, check that the RGB Mode is activated. To do so, go to the top menu and click on Image ➞ Mode ➞ RGB.


You are going to use this new layer to change the color of the glasses frame.

  1. Select the Rectangle Select Tool    on the left toolbar.

    Click and drag from one corner of the glasses’ bridge area to the opposite corner.

  2. Go to the top menu and click on Select ➞ Invert.

  5. You can see that the Background Color has changed from purple to green-turquoise.

    To fill the layer with the chosen color, select the Bucket Fill Tool    on the left toolbar.

    Once it is selected, the shape of the cursor changes.

  6. Move the mouse over the texture and click on it.

  7. The color of the layer has changed from transparent to green-turquoise.

  8. It is necessary to change the Layer Mode (Layers Tab) to see the changes on your texture.

  ○ Opacity Map

Just few steps left!

Previously, a dark green color was chosen for the lenses. To give the lenses a touch of transparency, let’s create an Opacity Map.

Opacity Map

An Opacity Map is a grayscale image that determines what areas of your texture are opaque, transparent, or translucent.

To learn more about this topic, please read the article Opacity Maps.

    • Go to the top menu and click on File ➞ Open.
    • Browse the folder where you saved the textures and select the Opacity Map.

  1. Set the Background Color to white and the Foreground Color to black.

    In this case, the current Foreground Color is black already. However, the current Background Color is dark green.

    To set the Background Color to white, click on it.

    A new window opens and a pallet of colors is displayed.

  2. Enter in the HTML Notation field the value ffffff and click OK.

    You can see that the Background Color has changed from dark green to white.

  3. Click on the Gradient Tool button .

  4. Click on the Tool Options button and then on the Gradient button.

  5. Select the premade gradient called FG to BG (RGB).

  6. To draw a gradient just click and drag.

    Click on the bottom of the current Opacity Map and drag until the top of it.

    The premade gradient previously selected is displayed along with a line that divides it in half.

    The line contains a Startpoint and an Endpoint .

  7. By clicking on a Stop, a small dialog appears with the selected stop’s information. For example, when the Endpoint is clicked, the following dialog pops up.

    The Position and the Color of a Stop can be changed through its small dialog.

    Typing a value in the Position field or clicking and dragging the Stop, varies its position value. The color can be changed by clicking on the Color field and selecting the desired one.

  8. Let’s add two Stops. These Stops will allow us to control the color of the gradient.

    To add Stops , click on the line.

  9. Make sure that each Stop has the right Color and Position values.

    • Start Endpoint Location and Color values: X = 125, Y = 256, and Color = FG (foreground color = black).
    • Stop 1 Location and Color values: Position = 15, and Left and Right Colors set to FG (foreground color = black).
    • Stop 2 Location and Color values: Position = 74, and Left and Right Colors set to BG (background color = white).
    • End Endpoint Location and Color values: X = 125, Y = 0, and Color = BG (background color = white).
  10. When the values are set, click the “enter” key on your keyboard to apply the changes on the gradient.

  11. The Opacity Map is ready!

  12. Let’s save it. Follow the same steps you did to save the previous textures.

    • Save the changes by going to the top menu and click on File ➞ Export As …
    • Select the folder where you want to save the texture, name it, and click on Select File Type (By Extension).

  13. Select the JPEG image option and click on Export.
