Blender 3D Modeling software: Glass Perfume Bottle Tutorial

Summary

This tutorial guides viewers through creating a realistic 3D bottle model with liquid in Blender. Starting from basic shape creation, the tutorial covers scaling, beveling, and extruding to shape the bottle, followed by adding thickness with the solidify modifier. It explains how to apply materials, simulate glass for the bottle, and adjust settings for realistic lighting using HDRI images. The final steps include adding a lid, applying subdivision surfaces, and refining the liquid inside the bottle with a glass material and custom settings. The result is a smooth, realistic bottle with liquid, making this a great project for Blender users interested in modeling and texturing.

Takeaways

• 😀 Use the 'A' key to select everything and the 'X' key to delete in Blender.
• 😀 Press 'Shift + A' to add a cylinder and enter edit mode by pressing 'Tab'.
• 😀 Scale the cylinder along the Z-axis using 'S' followed by 'Z', and move it with 'G' and 'Z'.
• 😀 Bevel the edges of the bottle using 'Ctrl + B', adjusting the segments with the scroll wheel.
• 😀 Apply the Solidify modifier for thickness and ensure it is applied before further steps.
• 😀 Use 'Ctrl + L' to select the outer layer of the bottle and 'H' to hide selected regions.
• 😀 Add a new material to the bottle, name it, and assign it to the object for later adjustments.
• 😀 Use the Subdivision Surface modifier to smooth the bottle and enable 'Shade Smooth'.
• 😀 For the lid, use a cylinder and scale it with 'S' and 'Z', then bevel the edges similarly.
• 😀 Switch the material to Glass BSDF for realistic rendering, adjusting roughness and IOR for the liquid effect.
• 😀 Add HDRI lighting for realistic reflections, then adjust the inner material to simulate liquid inside the bottle.

Q & A

What is the first step to creating the bottle in Blender?

The first step is to press 'A' to select everything and 'X' to delete any existing objects. Then, you add a cylinder by pressing 'Shift' + 'A'.

How do you scale the cylinder along the z-axis?

To scale the cylinder on the z-axis, press 'S' followed by 'Z'.

What is the purpose of holding 'Alt' and selecting the upper edge loop?

Holding 'Alt' and selecting the upper edge loop allows you to apply specific actions, such as beveling, to this selected loop of edges.

How do you bevel the edges of the bottle in Blender?

To bevel the edges, you can hold 'Ctrl' and press 'B' after selecting the edge, and use the scroll wheel to adjust the number of segments.

What does the Solidify modifier do in Blender?

The Solidify modifier adds thickness to the model, simulating the walls of the bottle. You can adjust the thickness and apply it once you are satisfied.

What is the function of pressing 'Ctrl' + 'L' when editing the bottle?

'Ctrl' + 'L' allows you to select the outer layer of the bottle, which is useful for isolating specific parts of the mesh for editing.

What does adding a new material in Blender do?

Adding a new material allows you to assign different properties, such as color or texture, to a part of the model. You can create multiple materials for different parts of the bottle, like the inner and outer surfaces.

Why is it important to apply the modifiers before continuing with other steps?

If you don’t apply the modifiers, such as the Solidify modifier, the next steps may not work correctly, as they rely on the modified geometry.

What is the purpose of using a subdivision surface modifier?

The subdivision surface modifier smoothens the bottle’s geometry, making it appear more polished and less angular.

Why is switching to the Cycles render engine important for this project?

Switching to the Cycles render engine allows for more realistic rendering of materials, especially glass, by simulating realistic light behavior.

How do you add realistic lighting to the scene?

You can add realistic lighting by using an HDRI (High Dynamic Range Image) as the environment texture. This can be loaded through the 'Color' popup menu in the render settings.

How do you simulate liquid inside the bottle?

To simulate liquid, adjust the inner material's base color and properties, like roughness and IOR (Index of Refraction), to make it appear like liquid while keeping the outer part of the bottle glassy.
