3D-Modelling a Doughnut using Blender | Tutorial

Summary

This tutorial provides a step-by-step guide on how to 3D model a donut using Blender, covering everything from basic navigation to the final render. Starting with a simple torus shape, the video explains how to add smoothness and sculpt realistic details, such as bumps and icing. The icing is then modeled and shaped using various tools, followed by adding sprinkles and realistic textures to the donut and icing. The final product is rendered with detailed lighting and material settings. The video concludes with a call to action, encouraging viewers to subscribe while also highlighting the ongoing Rohingya crisis and the importance of supporting humanitarian efforts.

Takeaways

• 😀 The tutorial focuses on creating a 3D donut in Blender, a free and powerful 3D modeling software.
• 😀 The video is inspired by Blender Guru on YouTube, a content creator known for educational Blender tutorials.
• 😀 To begin, the tutorial explains how to navigate the Blender 3D viewport, using tools like the middle mouse button for orbiting and panning.
• 😀 The first step is to create a donut shape by adding a torus and adjusting the minor and major radii to get the desired shape.
• 😀 A subdivision surface modifier is used to smooth out the donut's geometry, making it more rounded and realistic.
• 😀 The donut is sculpted with bumps using the draw tool in sculpting mode to give it a more realistic texture.
• 😀 To create the icing, the top half of the donut is duplicated, separated, and given thickness using a solidify modifier.
• 😀 The icing is further sculpted with proportional editing and the snap feature to create droopy, realistic drips.
• 😀 The video demonstrates how to apply materials to both the donut and icing, including subsurface scattering to make the icing look more realistic.
• 😀 The final step involves adding colorful sprinkles using a particle system, where the sprinkles are randomized in color using the object info node in the shader editor.
• 😀 The video concludes by encouraging viewers to donate to the UNICEF page for the Rohingya crisis, raising awareness about the humanitarian issue and the persecution of the Rohingya people.

Q & A

What software is used for this tutorial and is it free to use?

The software used in this tutorial is Blender, which is completely free to download and use.

How do you navigate in the 3D viewport in Blender?

In the 3D viewport, you can navigate by using the middle mouse button to orbit. To pan, use the shift + middle mouse button.

What is the purpose of the subdivision surface modifier in Blender?

The subdivision surface modifier adds more geometry to an object, smoothing out jagged edges to create a more polished appearance.

How do you add bumps to the donut to make it more realistic?

To add bumps to the donut, go to the Sculpting tab, select the draw tool, and adjust the strength and brush size to create imperfections on the surface.

How do you create the icing object for the donut in Blender?

To create the icing, duplicate the top half of the donut, separate it into its own object, and apply a solidify modifier to add thickness.

What does the solidify modifier do in this tutorial?

The solidify modifier adds thickness to the icing, making it more realistic and three-dimensional by ensuring it’s not too thin or papery.

How do you create the droopy bits of icing on the donut?

To create droopy icing, enter edit mode, enable proportional editing, and use the grab tool (G) to pull the icing down. For longer drips, use the extrude tool (E).

What is proportional editing and how is it useful in this tutorial?

Proportional editing allows you to move a single point and have surrounding points move proportionally, which helps in creating smooth and natural transitions, especially for the icing drips.

How do you add texture or bumps to the donut and icing in Blender?

Use the sculpting tools like the inflate brush for the icing and crease tool for the donut to add texture and simulate natural bumps and imperfections.

How do you apply materials and colors to the donut and icing?

To apply materials, go to the properties menu, add a new material, and adjust the colors, roughness, and subsurface scattering settings to create realistic textures for both the donut and icing.
