LES NOUVEAUTÉS DE LA VERSION 4.2 | Blender 4.2 [TUTO FR]

Introduction

This tutorial covers the new features introduced in Blender 4.2, as showcased in the video by Mykol. Whether you're a beginner or an experienced user, these updates can enhance your 3D modeling and rendering experience. We'll go through each new feature step by step, highlighting practical applications and tips.

Step 1: Explore the New Version of Eevee

Blender 4.2 brings significant improvements to Eevee, Blender’s real-time rendering engine. Key updates include:

• Global Illumination: Enhanced light interactions for more realistic rendering.
• Displacement Mapping: Apply detailed textures to surfaces.
• Subsurface Scattering (SSS): Improved SSS for realistic skin and translucent materials.
• Volumetric Enhancements: Better handling of volumetric effects.

Practical Tips

• Experiment with different lighting setups to take advantage of global illumination.
• Use displacement maps to add surface detail without increasing geometry.

Step 2: Implement Motion Blur in the Viewport

With Blender 4.2, you can now enable motion blur directly in the viewport, which allows for more accurate previews of animations.

How to Enable Motion Blur

1. Go to the Render Properties panel.
2. Under the Motion Blur section, check the box to enable it.
3. Adjust the settings to fit your scene.

Common Pitfalls

• Ensure that your animation settings are correctly configured for motion blur to display effectively.

Step 3: Utilize Portal Ray in Cycles

Portal Ray is a new feature in Cycles, allowing for more efficient light entry in enclosed spaces.

How to Use Portal Ray

1. Add a Portal Material to your light sources.
2. Set the correct light settings in the Shader Editor.

Real-World Application

This feature is particularly useful for interior scenes where light penetration is limited.

Step 4: Adjust Thickness and Dielectric Properties

Blender 4.2 improves how thickness and dielectric properties are handled in Cycles.

Steps to Adjust Properties

1. Select your object in the viewport.
2. Go to the Material Properties tab.
3. Use the new thickness settings to achieve more realistic translucency effects.

Step 5: Improve Volume Calculations

The update also enhances the calculations for volumetric effects in Cycles.

How to Access Volume Settings

1. In the Shader Editor, select your volumetric material.
2. Fine-tune the density and color settings for desired effects.

Practical Advice

• Combine different volumetric materials for unique effects in your scene.

Step 6: Explore the New Extension System

Blender 4.2 introduces a new system for managing extensions and add-ons, making it easier to enhance your workflow.

How to Manage Extensions

1. Go to Edit > Preferences > Add-ons.
2. Browse and install new extensions from the available options.

Step 7: Use the New Khronos PBR Neutral Color Mapper

This new tone mapper in Blender 4.2 helps achieve better color accuracy in your renders.

Steps to Use the Tone Mapper

1. Navigate to the Render Properties.
2. Under Color Management, select the Khronos PBR Neutral option.

Step 8: Explore New Polyline Brushes for Sculpting

The introduction of new polyline brushes in the sculpting mode allows for more versatile modeling options.

How to Access New Brushes

1. Enter Sculpt Mode.
2. Select the new brushes from the brush menu.

Step 9: Enhance Geometry Nodes with Matrix Calculations

Blender 4.2 adds the ability to perform matrix calculations directly in Geometry Nodes.

Using Matrix Calculations

1. Open the Geometry Nodes workspace.
2. Add a new node that utilizes matrix operations to manipulate geometry.

Step 10: Improve Video Sequence Editor (VSE) Features

Improvements to the VSE make video editing more efficient.

Key Enhancements

• Streamlined interface for managing clips.
• New export options for collections.

Conclusion

Blender 4.2 introduces a range of powerful features that enhance rendering, modeling, and video editing workflows. Experiment with these new tools to leverage their full potential in your projects.
