Normal maps in 3D models are texture techniques that simulate surface detail (like bumps or scratches) without extra geometry, while Roblox 3D models are platform-specific assets optimized for Roblox’s real-time performance.
- Normal maps: Enhance realism by adding detail to existing meshes—no additional polygons needed. - Roblox models: Prioritize Roblox Studio compatibility, simpler geometry, and adherence to the platform’s mesh/asset limits.
For Roblox creators, use normal maps sparingly to add subtle detail without exceeding performance constraints.
