Part 2/6:
First, navigate to the shading tab and switch the view from object to world. Introduce a gradient texture, linking it to the background color. Utilize mapping and texture coordinate nodes to orient the horizon. Adjust the gradient's color values, ultimately achieving a rich dark blue and dark red palette. Organizing these elements into frames can enhance workflow life.
Next, create a galaxy effect by layering additional gradient textures and refining star placement. A varoni texture generates a sparkling starfield, which is further enhanced by duplicating components to enrich the density in the galaxy. This meticulous assembly culminates in a stunning celestial backdrop.
