LightImage

The LightImage class represents image-based lighting (IBL). It supports manual assignment or automatic generation of diffuse and specular cubemap textures from environment maps. Multiple LightImage instances can be placed within a scene, with the renderer automatically blending lighting parameters from the nearest sources. The class provides adjustable light intensity and spatial settings for precise control over ambient lighting.
