Important Notes

- All required textures are packed in the blend file. Should there be any issues with them, there is an included “Textures” folder that contains every texture file in png format. 

- Not every object uses textures. The objects that do not use textures use Blender materials created using Blender’s standard shader editor.

- All featured images were rendered using Cycles. The cover image scene only works correctly with cycles due to the shadow catcher object and the translucent diffuser object. However, the scene can still be rendered in EEVEE with the correct modifications. 

- The “glass” material contains two node groups: one optimized for cycles, and one optimized for EEVEE. The selected node group should correspond with the render engine being used. 

- The parent object that contains the components of the device (named “Base”) can be used to perform transformations including location, rotation, and scale. This object can also be used to edit various aspects of the device including the keyboard backlight, color options, and wallpaper type.

- The custom properties contained within the parent object can be found in two places: The “Custom Properties” drop-down in the “Object Properties” tab or the “Properties” drop down in the “Item” tab.

- The first custom property on the parent object is the Camera Indicator toggle. This toggle can be used to enable or disable the camera indicator light right next to the webcam on the top of the screen.

- The second custom property on the parent object is the keyboard backlight slider. This custom property is a float value from 0 to 2 (precise to the 3rd decimal place) that drives the emission strength slider in the keyboard material. This slider can be used to increase and decrease the brightness of the keyboard backlight, where 0 would be the minimum brightness (off), and 2 would be the maximum brightness.

- The third custom property on the parent object is the color selection toggle. This custom property is an integer value from 1 to 4 that drives the factor of a more in-depth Color Ramp node group. The M2 MacBook Air has 4 color options. This factor value cycles through the MacBook Air’s 4 color options: Midnight, Starlight, Space Gray, and Silver. The displayed factory wallpaper depends on the selected color and will change with the color. There is a specific factory wallpaper for each color option. 

- The fourth custom property on the parent object is the wallpaper toggle. This custom property is an integer value between 0 and 1 that drives the factor of a mix node in the screen material that affects the displayed wallpaper. The toggle can be used to display one of the factory wallpapers, or a custom wallpaper the user can choose. When set to 0, the wallpaper would be set to a factory wallpaper and when set to 1, the wallpaper would be set to a custom wallpaper the user can change. The selected factory wallpaper would change depending on the selected color. The custom wallpaper can be changed by navigating to the shader editor and selecting an image in the lower most image texture. This image texture should already have an image named “Wallpaper 4 (light).png” selected. This is what should be changed.
