Session 02: Installing Extensions – Screen Cast Keys


🔹 Module 1: Introduction

  • Blender is an open-source 3D creation suite written in C++ with Python integration.
  • Blender 5 is in alpha stage; some add-ons/extensions may not yet be supported.
  • For stability and production work, we will start with Blender 4.5.2 LTS.

Learning Outcome:
Understand why we are using Blender 4.5.2 and what to expect from Blender 5.


🔹 Module 2: Launching Blender

  • Double-click on Blender 4.5.2 LTS.
  • Confirm the version number on the top right corner of the Quick Setup screen.

🔹 Module 3: Quick Setup

Step 2: Configure Quick Setup

  • Language: Select English (US) → recommended for reliable shortcuts. (Hindi is available but may affect shortcuts).
