PBR/RTX Conversion

The converter automatically detects and converts LabPBR textures:

Conversion Process:

• Normal Maps: _n.png → Bedrock normal maps
• Specular Maps: _s.png → Bedrock MER maps (Metallic/Emissive/Roughness)
• Texture Sets: Automatic JSON generation for RTX compatibility

Conversion Flow

Requirements

• Input: Java Edition resource pack (.zip file)
• Output: Bedrock Edition resource pack (.mcpack file)
• Supports: Minecraft Java Edition 1.8+ textures
• Target: Minecraft Bedrock Edition with RTX support
