Lightmaps vs Real-Time Global Illumination
Developers should learn and use lightmaps when creating 3D games or applications where realistic, static lighting is crucial, such as in architectural visualization, cinematic scenes, or performance-intensive games on limited hardware meets developers should learn rtgi to create visually stunning and realistic real-time graphics, especially in video games, architectural visualizations, and virtual reality, where accurate lighting enhances immersion and visual fidelity. Here's our take.
Lightmaps

Lightmaps
Nice PickDevelopers should learn and use lightmaps when creating 3D games or applications where realistic, static lighting is crucial, such as in architectural visualization, cinematic scenes, or performance-intensive games on limited hardware
Pros
- +They are particularly valuable for optimizing real-time rendering by offloading complex lighting computations to pre-processing, enabling detailed shadows and global illumination without taxing the GPU during gameplay
- +Related to: global-illumination, texture-mapping
Cons
- -Specific tradeoffs depend on your use case
Real-Time Global Illumination
Developers should learn RTGI to create visually stunning and realistic real-time graphics, especially in video games, architectural visualizations, and virtual reality, where accurate lighting enhances immersion and visual fidelity
Pros
- +It's crucial for modern game engines and graphics pipelines to support dynamic lighting scenarios, such as moving light sources or changing environments, without pre-baked solutions
- +Related to: ray-tracing, path-tracing
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Lightmaps if: You want they are particularly valuable for optimizing real-time rendering by offloading complex lighting computations to pre-processing, enabling detailed shadows and global illumination without taxing the gpu during gameplay and can live with specific tradeoffs depend on your use case.
Use Real-Time Global Illumination if: You prioritize it's crucial for modern game engines and graphics pipelines to support dynamic lighting scenarios, such as moving light sources or changing environments, without pre-baked solutions over what Lightmaps offers.
