Hi All,
I have tried enabling shadow casting with ReacAreaLight, but the shadows don't appear to be affected. Is it currently possible to cast shadows with ReacAreaLight, or might I be missing some necessary settings?
Thanks in advance!

Shadows with RectAreaLight in Three.js
Based on the available documentation, RectAreaLight does not support shadow casting in Three.js. The shadow-capable lights in Three.js are:
- PointLight (using PointLightShadow)
- DirectionalLight (using DirectionalLightShadow)
- SpotLight (using SpotLightShadow)
RectAreaLight is not included in this list because it doesn't have a corresponding shadow class like the other light types. This is a limitation of the current implementation.
If you need to simulate the effect of an area light with shadows, you might consider:
- Using multiple SpotLights or PointLights to approximate the area light effect
- Using an alternative rendering technique like baking shadows into textures
- Implementing a custom shader solution
For realistic lighting that includes the area light effect with shadows, you might need to use a combination of different light types together in your scene.
