Lecture Notes: Blender 4.0 Tutorial

Introduction

  • Blender 4.0 introduces a change for more realistic default settings.
  • New technology is enhancing 3D tool applications.
  • Subscribe to 'This Week in 3D' newsletter for weekly updates on 3D tech.

Tutorial Series: The Donut Show

  • Objective: Create realistic donut and icing in Blender.

Part 1 Recap

  • Completed donut base.

Part 2: Creating Icing

Duplicating the Donut for Icing

  • Shortcut: Shift + D (to duplicate).
  • Placement State: Cancel movement with Escape or right-click.
  • Naming Objects:
    • Double-click in Outliner.
    • Use F2 in 3D viewport.

Edit Mode for Icing

  • Enter Edit Mode: Press Tab.
  • Bottom half of mesh (donut) is deleted to create top icing layer.
  • Select through mesh:
    • Enable X-ray from top navigation.
    • Drag-select to ensure full selection.

Working with Mesh

  • Orthographic Mode: Click on X or Y axis in the gizmo.
  • Deleting Vertices: Use the Delete key, choose vertices option.

Flickering Issue

  • Caused by overlapping faces.
  • Known as Z-fighting; common in 3D rendering.

Solidifier Modifier

  • Adding Thickness:
    • Add Modifier > Generate > Solidify.
    • Adjust Offset in settings (usually set to 1).
  • Thickness Adjustment: Set to 0.25 for realistic effect.

Shaping the Icing

  • Edit Mode: Hide solidify modifier for better editing.
  • Proportional Editing:
    • Enable and adjust fall-off to shape edges.
    • Snapping: Enable Face snapping for accurate placement.

Geometry Adjustments

  • Subdivision Surface Modifier:
    • Apply to add geometry details.
    • Enhances mesh detail for better shaping.

Advanced Techniques

  • Using Select More/Less: Alt + left-click to select rings; Ctrl + Plus/Minus for more selection.
  • Hide/Reveal Mesh: H to hide; Alt + H to reveal.

Finalizing Icing Shape

  • Use proportional editing to create natural wavy edges.
  • Incorporate snapping and proportional editing for realistic dripping effects.

Fixing Edge Issues

  • Subdivision Surface Modifier: Adds rounded edges.
  • Crease Adjustment: Inner edge data adjusted for realism.

Creating Drips

  • Using Extrude: Shift + select two vertices and hit E.
  • Adding Detail: Extrude multiple times for detailed drips.
  • Ensure Conformity: Keep drips conforming to donut shape.

Conclusion

  • Complex tutorial with emphasis on Blender shortcuts and techniques.
  • Encourages use of Discord for help.
  • Next part continuation link provided.

Additional Notes

  • Common Issues: Addressed shading artifacts and Z-fighting.
  • Community Support: Utilize Discord and available resources.
  • Self-Promotion: Reminder to subscribe for more content.
