Intro to Blender

Unleash your creativity by building custom 3D mesh objects. This guide covers the absolute basics of Blender and how to get your creations into Alife Virtual.

Step 1: Get Blender

Blender is a powerful and completely free 3D creation suite. You can download the recommended version from our website to ensure compatibility.

The Blender Basics

Blender can seem complex, but you only need to know a few things to get started.

Navigating the 3D Viewport

This is your main workspace. Use these controls to look around:

  • Orbit: Hold the Middle Mouse Button and drag.
  • Pan/Move: Hold Shift + Middle Mouse Button and drag.
  • Zoom: Use the Mouse Scroll Wheel.

Adding & Manipulating Objects

You'll build things from basic shapes called "primitives."

  • Add Object: Press Shift + A and choose from the `Mesh` menu (e.g., Cube, Sphere).
  • Move: Select an object and press G.
  • Rotate: Select an object and press R.
  • Scale: Select an object and press S.

Object Mode vs. Edit Mode

This is a core concept! Switch between modes using the TAB key.

  • Object Mode: Move, rotate, and scale the entire object.
  • Edit Mode: Modify the building blocks of the object: its vertices (points), edges (lines), and faces (surfaces).

The Most Important Step: Exporting for Alife Virtual

To upload your model to Alife Virtual, you must export it in the correct format: Collada (.dae).

Export Process

  1. In Object Mode, select the object you want to export.
  2. Go to File > Export > Collada (Default) (.dae).
  3. In the Export window on the right, check the box Selection Only. This is very important to avoid exporting the camera and lights.
  4. Name your file and click Export Collada.
Your `.dae` file is now ready! You can upload it in the Alife Virtual viewer by going to `Build > Upload > Model...` and selecting your file.

What to Learn Next

You've successfully made and exported your first model! Here are the next creative steps.

Suggestions for New Content and Images

To Make This Guide Even Better:

  • `blender-export-dae.jpg`: This is the most critical new image. It should be a screenshot of the Blender Export window for Collada (.dae), with a big red arrow pointing to the "Selection Only" checkbox. This will prevent countless user errors.
  • Create a Follow-Up Guide: This guide only covers the model shape. The next logical step is texturing. A new guide, `howto/11-blender-uv-texturing.php`, would be the perfect follow-up, explaining UV unwrapping and applying textures.
  • Mention Land Impact: In the follow-up texturing guide, you should explain the concept of "Land Impact" (prim cost) and how model complexity and textures affect it. This is vital information for creators.
