In my futuristic setting, I am incorporating RectAreaLights to mimic strip lights. However, I am encountering a performance issue as my frames per second (fps) drop significantly when using these lights, typically not exceeding 20 or 30. On the other hand, switching to different types of lights such as PointLight or SpotLight resolves this problem and maintains a stable 60 fps.
Are there any techniques or solutions available to enhance performance while using RectAreaLights?
Rectangular area lights can be quite costly to use, especially in large numbers. One workaround could be to use just one or two lights and strategically place them behind geometry for a similar effect. Another option is to incorporate the UnrealBlur post processing effect through EffectComposer to achieve multiple glowing elements, although this may sacrifice some realism and require careful adjustment of contrast to make the glow stand out.
