| Option | Description |
|--------|-------------|
| `-e` | Extract only - unpack `.chr` without conversion |
| `-t` | Output as `.glTF` (text) instead of `.glb` (binary) |
| `-b` | Batch mode - process all `.chr` files in directory |
| `-i`, `--input` | Input path |
| `-o`, `--output` | Output path |
| `-e`, `--extract` | Extract only - unpack `.chr` without conversion |
| `-f`, `--format` | Output format. `GLTF` for text format or `GLB` for binary (default: `GLB`) |
| `-b`, `--batch` | Batch mode - process all `.chr` files in directory |
| `-h`, `--help` | Show help |
## Usage
### Basic Syntax
```
dq8chr2glb.exe <input_file> <output_dir> [options]
dq8chr2glb.exe <input_dir> -b # Batch mode
dq8chr2glb.exe # No args for get help
dq8chr2glb.exe -i <input_file> -o <output_dir> [options]
dq8chr2glb.exe -i <input_dir> -b # Batch mode
```
### Examples
```
dq8chr2glb.exe "C:\Games\DQ8\@DATA.DAT\chara\ap002.chr" "C:\Exports"
dq8chr2glb.exe "C:\Games\DQ8\@DATA.DAT\chara" -b
dq8chr2glb.exe "C:\Games\DQ8\@DATA.DAT\chara\ap002.chr" "C:\Exports" -e
dq8chr2glb.exe "C:\Games\DQ8\@DATA.DAT\chara" -b -e
dq8chr2glb.exe -i "C:\Games\DQ8\@DATA.DAT\chara\ap002.chr" -o "C:\Exports"
dq8chr2glb.exe -i "C:\Games\DQ8\@DATA.DAT\chara" -b
dq8chr2glb.exe -i "C:\Games\DQ8\@DATA.DAT\chara\ap002.chr" -o "C:\Exports" -e
dq8chr2glb.exe -i "C:\Games\DQ8\@DATA.DAT\chara" -b -t GLTF
