# UE 5.4.1 Installation Status

## Current Status

**Installation Started**: Ready to begin
**Mode**: Optimized (4 cores, ~80-100GB disk space)

## Installation Steps

### ✅ Completed
1. Installation script created and optimized
2. TODO list updated
3. Monitoring script created

### ⏳ Pending (Requires Manual Steps)

#### Step 1: Link GitHub to Epic Games (REQUIRED)
**Status**: ⚠️ Must be completed before installation

1. Visit: https://www.unrealengine.com/en-US/ue-on-github
2. Sign in with Epic Games account
3. Link your GitHub account
4. Accept Unreal Engine license

**Verify access:**
```bash
git ls-remote https://github.com/EpicGames/UnrealEngine.git
```

#### Step 2: Run Installation Script
**Status**: Ready to run

The installation requires `sudo` access for installing system dependencies. You have two options:

**Option A: Run Full Automated Script**
```bash
cd /home/intlc/projects/metaverseDubai
./scripts/install_ue5_5.4.1_auto.sh
```
*Note: Will prompt for sudo password when needed*

**Option B: Manual Step-by-Step**
```bash
# 1. Install dependencies (requires sudo)
sudo apt update && sudo apt install -y \
  build-essential clang cmake ninja-build mono-devel python3 \
  python3-pip git git-lfs curl wget unzip \
  libvulkan-dev libxcb-xinput-dev libgtk-3-dev \
  libxrandr-dev libxinerama-dev libxi-dev libsdl2-dev \
  libssl-dev libicu-dev libxml2-dev libxcursor-dev \
  libxcb-icccm4-dev libxcb-image0-dev libxcb-keysyms1-dev \
  libxcb-render-util0-dev libxcb-xkb-dev libxkbcommon-dev \
  libxkbcommon-x11-dev mesa-common-dev libgl1-mesa-dev \
  dotnet-sdk-6.0 libc++-dev libc++abi-dev

# 2. Setup Git LFS
git lfs install

# 3. Clone repository
cd ~
git clone --depth=1 --branch 5.4.1 https://github.com/EpicGames/UnrealEngine.git UnrealEngine

# 4. Run Setup
cd ~/UnrealEngine
./Setup.sh

# 5. Generate project files
./GenerateProjectFiles.sh -game -engine

# 6. Build (4 cores, 4-6+ hours)
make -j4 UnrealEditor

# 7. Clean up
find Engine/Intermediate -type f -name "*.o" -delete
find Engine/Intermediate -type f -name "*.obj" -delete
```

## Monitor Installation

Check installation progress:
```bash
./scripts/monitor_ue5_install.sh
```

## Installation Timeline

| Step | Duration | Status |
|------|----------|--------|
| Install dependencies | 5-10 min | ⏳ Pending |
| Clone repository | 30-60 min | ⏳ Pending |
| Run Setup.sh | 30-60 min | ⏳ Pending |
| Generate project files | 5-10 min | ⏳ Pending |
| Build Unreal Engine | 4-6+ hours | ⏳ Pending |
| Cleanup | 5-10 min | ⏳ Pending |
| **Total** | **5-8+ hours** | ⏳ Pending |

## Configuration

- **CPU Cores**: 4 (configurable in script)
- **Disk Space**: ~80-100GB
- **Build Target**: Development Editor only
- **Optimizations**: Enabled (shallow clone, cleanup, minimal build)

## Next Steps After Installation

1. Verify installation:
   ```bash
   ~/UnrealEngine/Engine/Binaries/Linux/UnrealEditor -version
   ```

2. Launch Unreal Editor:
   ```bash
   ~/launch_ue5.sh
   ```

3. Create project:
   - Follow [docs/setup/UE5_INSTALLATION.md](docs/setup/UE5_INSTALLATION.md)
   - Follow [docs/setup/PROJECT_SETTINGS.md](docs/setup/PROJECT_SETTINGS.md)

## Troubleshooting

### GitHub Access Denied
- Ensure GitHub is linked to Epic Games account
- Visit: https://www.unrealengine.com/en-US/ue-on-github

### Sudo Password Required
- The script will prompt for sudo password when installing dependencies
- This is normal and required for system package installation

### Build Takes Too Long
- Normal: 4-6+ hours with 4 cores
- To speed up: Edit script, change `NUM_CORES=4` to higher number (if you have more RAM)

### Out of Disk Space
- Expected usage: ~80-100GB
- If running low, see [UE5_DISK_SPACE_OPTIMIZATION.md](UE5_DISK_SPACE_OPTIMIZATION.md)
