Beginner Blender 4.0 Tutorial - Full Course

Introduction

This tutorial is designed to guide complete beginners through the process of creating a visually appealing donut scene in Blender 4.0. By the end of this course, you will have a solid understanding of Blender's core features, including modeling, texturing, lighting, and rendering. The skills you gain here will empower you to start your own projects confidently.

Chapter 1: Download and Install Blender

• Visit blender.org and click the download button.
• For Windows, double-click the downloaded file and follow the installation prompts. For Mac, drag the application into your Applications folder.
• Launch Blender and close the splash screen by clicking anywhere on it.
• Familiarize yourself with the interface, focusing on the 3D viewport where you will spend most of your time.

Chapter 2: Interface and Navigation

• The main area is the 3D viewport where you will create your models.
• Use the shortcut Shift + A to add objects, such as the monkey head for testing.
• To orbit around the scene, use the middle mouse button. Laptop users can emulate a three-button mouse by enabling it in preferences.
• Zoom in/out using the scroll wheel or by holding Ctrl + Middle Mouse Button.
• Pan by holding Shift + Middle Mouse Button.

Chapter 3: Basic Object Manipulation

• To delete the default cube, select it and press the Delete key.
• Use G to grab/move objects. Confirm the movement with a left click or cancel it with Esc.
• Move objects along specific axes using G followed by X, Y, or Z.
• To rotate, select an object, press R, and use the same axes for precision.

Chapter 4: Create the Donut Shape

• To create a donut shape, start with a Torus:
  • Delete any existing objects.
  • Press Shift + A, select Mesh, then Torus.
  • Adjust the parameters in the bottom left corner after adding it to change the major and minor segments (aim for low poly for easier handling).
• Apply Shade Smooth to the torus for a more appealing look.

Chapter 5: Adding Materials to the Donut

• Select the donut, go to the Material Properties, and click New.
• Change the base color to your desired icing color.
• Use the Subsurface Scattering settings to mimic how light interacts with the icing:
  • Set weight to 1, radius to 1, and scale to 0.1 for a realistic look.

Chapter 6: Adding Sprinkles

• Create sprinkles using either the UV sphere or by duplicating the donut:
  • For round sprinkles, create a UV sphere and scale it down.
  • For long sprinkles, create a cylinder, scale it, and modify it to the desired shape.
• Use Geometry Nodes to scatter the sprinkles on the donut:
  • Add a Point Distribute node and connect it to the Join Geometry node.

Chapter 7: Adjusting Lighting and Background

• Set up your environment:
  • Delete any default lights and instead create a Sky Texture for natural lighting.
  • Adjust the sun's position and size for softer shadows.
  • Use Area Lights for additional fill light, adjusting the intensity as necessary.

Chapter 8: Compositing and Final Touches

• Use the Compositor for post-processing effects:
  • Add glare effects to enhance the metallic look of the sprinkles.
  • Use Color Management to adjust exposure and contrast.
• Ensure all elements are visible in the render and make final adjustments as needed.
• Create a Depth of Field effect to focus on the donuts while blurring the background.

Chapter 9: Rendering the Scene

• Set your render settings:
  • Go to Render Properties and choose Cycles for better quality.
  • Adjust sample rates (aim for 500 samples for a good balance of quality and speed).
• Render your animation by going to Render > Render Animation.
• Save each frame as PNG to prevent data loss.

Conclusion

Congratulations on completing this comprehensive beginner’s tutorial on Blender! You have learned how to model a donut scene, apply materials, set up lighting, and render your project. Continue exploring Blender's features and consider experimenting with variations of your donut scene, like adding different colors, sprinkles, or even a themed background.
