🔧 Installation and Setup

⚠️ Mac and Linux Users

macOS: Unreal Engine 5 supports macOS, but with some limitations. You'll need macOS 12.5 Monterey or later, and performance may not match Windows due to differences in graphics API support (Metal vs. DirectX 12).

Linux: UE5 supports Linux (Ubuntu 20.04 or CentOS 7), but this is primarily aimed at advanced users and server/rendering farm setups. Most learning resources and tutorials assume Windows.

Recommendation: If you're new to Unreal Engine, Windows 10/11 will give you the smoothest experience and best compatibility.

✅ Storage Pro Tip

Install Unreal Engine on an SSD if possible, even if you store project files on a larger HDD. The engine's startup and compile times will be significantly faster. A good workflow is: Engine on SSD, active project on SSD, archived projects on HDD.

💡 What If My PC Doesn't Meet Requirements?

Don't panic! You can still learn Unreal Engine on lower-spec hardware, but you may need to:

• Work with smaller, simpler projects
• Disable real-time features like Lumen and Nanite
• Use lower viewport quality settings
• Be patient with longer compile and load times

Many successful developers started learning on modest hardware and upgraded as their skills (and budgets) grew.

📝 Account Creation Walkthrough

   You can create an account using:

   • Email address: Most straightforward option
   • Google, Facebook, Apple, etc.: Convenient if you use these services

   Recommendation: Using email gives you the most control and doesn't tie your account to third-party services.

3. Fill Out the Registration Form
   • Country: Select your location (affects regional availability and tax calculations)
   • First and Last Name: Use your real name
   • Display Name: This is what others see in forums and community features (can be changed later)
   • Email Address: Use a reliable email you check regularly
   • Password: Choose a strong password (at least 8 characters, mix of letters, numbers, symbols)
4. Agree to Terms
   • Review the Terms of Service
   • Check the box to accept (required)
   • Optionally subscribe to email updates (you can unsubscribe later)
5. Verify Your Email
   • Epic will send a verification email to the address you provided
   • Check your inbox (and spam folder if needed)
   • Click the verification link in the email
   • Your account is now active!

⚠️ Account Security Tips

• Enable Two-Factor Authentication (2FA): After creating your account, go to Account Settings → Password & Security → Enable 2FA. This protects your account from unauthorized access.
• Use a unique password: Don't reuse passwords from other services

⚠️ Slow Download Speeds?

If your download is extremely slow or keeps pausing:

• Check your internet connection: Run a speed test at fast.com
• Pause other downloads: Close Steam, torrent clients, and other bandwidth-heavy applications
• Try downloading during off-peak hours: Epic's servers may be less congested late at night or early morning
• Check firewall/antivirus: Some security software can throttle large downloads
• Be patient: This is a large download, and it may take several hours on slower connections

✅ Pro Tip: Install Location Strategy

If you have multiple drives, consider this setup:

• SSD: Install the engine itself here for fast startup and compilation
• SSD: Keep your active project(s) here while you're working on them
• HDD: Move completed or archived projects here to save SSD space

The speed difference between SSD and HDD for engine startup can be 30 seconds vs. 2-3 minutes!

📖 Version Number Breakdown

Example: Unreal Engine 5.4.2

• 5 = Major version (fundamental engine architecture)
• 4 = Minor version (new features, improvements)
• 2 = Patch version (bug fixes, small improvements)

✅ Recommended for Beginners

Install the latest stable minor version with the highest patch number.

For example, if available versions are:

• 5.5.0 (just released)
• 5.4.4 (stable, well-tested)
• 5.3.2 (older but rock-solid)

→ Install 5.4.4 for the best balance of features and stability.

Avoid the bleeding edge (5.5.0) until it's had a few patches, and avoid very old versions (5.2.x) unless you have a specific compatibility reason.

💡 Managing Multiple Versions

The Epic Games Launcher makes it easy to manage multiple engine versions:

• Each version installs to its own directory (e.g., UE_5.3, UE_5.4)
• Projects remember which version they were created with
• You can switch between versions easily from the Launcher
• Each version takes 40-60 GB of disk space, so plan accordingly

⚠️ Version Upgrade Best Practices

• Always backup before upgrading: Make a complete copy of your project folder
• Test in a copy first: Don't upgrade your only copy of an important project
• Expect to fix things: APIs change, blueprints may need updates, plugins might break
• Read release notes: Check what changed between versions before upgrading
• Stay on stable versions for important work: Don't upgrade mid-project unless necessary

💡 First Launch Takes Longer

The very first time you launch Unreal Engine, it takes longer than subsequent launches because the engine is:

• Compiling shaders for your graphics card
• Building initial caches
• Setting up configuration files

On an SSD, first launch might take 2-3 minutes. On an HDD, it could take 5-10 minutes. Subsequent launches will be much faster (30-60 seconds on SSD, 2-3 minutes on HDD).

📖 Project Template

Project Templates are pre-configured starting points that include relevant assets, settings, and example content for specific use cases. For example, the "First Person" template includes a character controller, sample level, and weapon mechanics ready to customize.

✅ What You Should See

If your installation was successful, you should see:

• The Unreal Project Browser window with various template categories
• No error messages or crashes
• Template preview images loading properly

If you see error messages, check the Troubleshooting section at the end of this lesson.

💡 Editor Preferences vs. Project Settings

There are two types of settings in Unreal Engine:

• Editor Preferences: Personal settings that apply to you across all projects (interface, hotkeys, auto-save frequency)
• Project Settings: Settings specific to the current project (rendering quality, input mappings, physics)

We're focusing on Editor Preferences here since they're global to your Unreal Engine installation.

✅ Recommended First-Time Setup

For your first time using Unreal Engine, configure these essential settings:

1. Enable Auto-Save: Go to General → Loading & Saving → Enable Auto Save Maps/Content, set interval to 5 minutes
2. Adjust UI Scale: Go to General → Appearance → UI Scale, adjust if text is too small/large
3. Show Frame Rate: Go to General → Performance → Show Frame Rate and Memory in Stats

You can explore and customize other settings as you become more familiar with the engine.

⚠️ Don't Overwhelm Yourself

There are hundreds of preference options! You don't need to configure everything now. Start with the essentials listed above, and adjust other settings as you discover features you want to customize. The default settings work well for most users.
