Breaking your barn mesh into simpler pieces could potentially help with Lumen’s handling of complex geometry, but it’s not necessarily the only solution. Lumen’s performance is influenced by various factors, including mesh complexity, lighting complexity, and the overall scene setup.
Since you’ve mentioned that your meshes consist of quads and triangles with no manifold geometry and have decent UV maps, it sounds like they are already optimized in terms of geometry. However, there are a few other considerations to keep in mind:
Lightmap Resolution: Strong text Ensure that the lightmap resolution for each mesh is appropriate. Higher-resolution lightmaps can improve lighting quality but may also increase processing overhead.
Lighting Complexity: Lumen’s performance can also be affected by the complexity of your lighting setup. Try simplifying your lighting if it’s too complex.
Optimization: Beyond mesh complexity, consider other optimizations such as reducing the number of overlapping geometry, optimizing material shaders, and minimizing overdraw.
Testing: Experiment with different configurations to see what works best for your scene. Sometimes, minor adjustments can have a significant impact on performance.
Lumen’s Limitations: Keep in mind that while Lumen is designed to handle dynamic global illumination efficiently, there may still be limitations, especially in complex scenes. If you’re pushing the boundaries of real-time global illumination, you may encounter performance issues.
