Step 1: Creating the Cylinder Shape
- Open Blender and delete the default cube by selecting it and pressing the “Delete” key.
- Press Shift + A to open the “Add” menu and select “Mesh” > “Cylinder” to add a cylinder object.
- In the “Tool Shelf” panel (press T to toggle), adjust the settings for the cylinder: set the “Vertices” to 32, “Depth” to your desired height for the bottle, and “Radius” to your desired size for the bottle.
- Press S to scale the cylinder to your preferred shape.
Step 2: Adding Thickness to the Walls
- In the “Modifier” tab of the properties panel (press the wrench icon), click “Add Modifier” and select “Solidify”.
- Adjust the “Thickness” value to add thickness to the walls of the bottle. You can preview the effect by clicking the “Eye” icon next to the modifier.
Step 3: Creating the Cap
- Select the top face of the bottle.
- Press E to extrude and immediately press Esc to cancel the movement.
- Press S to scale the extruded face to create the cap of the bottle.
Step 4: Creating the Water Material
- Switch to the “Shader Editor” workspace by selecting it from the top menu.
- Select the bottle object, go to the “Materials” tab in the properties panel, and click the “+” button to add a new material.
- In the “Shader Editor”, delete the default “Principled BSDF” node.
- Press Shift + A and add a “Glass BSDF” node and a “Volume Absorption” node.
- Connect the “Glass BSDF” node to the “Material Output” node.
- Connect the “Volume Absorption” node to the “Volume” input of the “Glass BSDF” node.
- Adjust the color and density of the “Volume Absorption” node to achieve the desired water effect.
Step 5: Adding a Label
- Prepare an image texture for the label of the bottle.
- In the “Shader Editor”, press Shift + A and add an “Image Texture” node.
- Open your label image using the “Image Texture” node.
- Add a “Mapping” node and connect it to the “Vector” input of the “Image Texture” node.
- Connect the “Image Texture” node to the “Base Color” input of the “Glass BSDF” node.
- Adjust the position and scale of the label using the “Mapping” node.
Step 6: Lighting and Camera Setup
- Switch to the “Layout” workspace to adjust the lighting and camera.
- Press Shift + A and add a “Point” or “Area” light to illuminate the scene.
- Position and adjust the properties of the light to achieve the desired lighting effect.
- Press Numpad 0 to switch to the camera view.
- Position and adjust the camera angle to frame the bottle nicely.
- Optionally, add additional lights or adjust the world environment settings for better results.
Step 7: Rendering the Final Image
- Switch back to the “Shader Editor” workspace.
- In the “Render” tab of the properties panel, adjust the output resolution and other settings as desired.
- Click the “Render” button to render the final image of the 3D water bottle.
That’s it! Following these steps, you should be able to create a realistic water bottle 3D model in Blender, complete with a water-filled appearance, label, and suitable lighting and camera setup.
