Light

Light brings a complete set of illumination nodes to BeeGraphy, giving you precise control over how your 3D models are lit. It covers everything from soft, ambient fills to sharp, shadow-casting sunbeams, so you can build lighting rigs that make surfaces, materials, and details read clearly. All nodes live in a single Light group and are designed to be combined freely in your scene graph.

Node Groups

Light

This group contains the full range of light sources that the BeeGraphy engine supports.

• Ambient Light provides uniform, directionless lighting across the whole scene and never casts shadows. It is useful for lifting the overall brightness or adding a subtle color wash to shadow areas.
• Directional Light simulates a distant source such as the sun, emitting parallel rays from a consistent direction. It is the main choice for strong, readable shadows and clear form definition.
• Point Light emits light equally in all directions from a single location. It behaves like a bare bulb and is good for local highlights, lamps, or filling corners of a scene.
• Spot Light projects a cone of light from a point, with adjustable angle and falloff. It is ideal for accent lighting, stage-style effects, or drawing attention to a specific part of a model.
• Rect Area Light creates soft, area-based illumination from a rectangular surface. It produces gentle shadows and is well suited to simulating windows, softboxes, or ceiling panels.
• Hemisphere Light blends two colors across the sky and ground, with no position or shadow information. It is a fast way to create natural-looking ambient environments for outdoor scenes.

Example Setups

Soft Studio Lighting

Combine Hemisphere Light for a cool sky-to-warm-ground ambient base, then add a large Rect Area Light positioned above and slightly in front of the model. Lower the area light intensity until shadows stay visible but soft. This gives product shots a clean, non-directional fill that keeps materials readable.

Sunlight with Shadows

Use a single Directional Light with castShadow enabled and a high shadow.mapSize. Position it at an angle that rakes across the geometry, then add a low-intensity Ambient Light so the shadow side does not go fully black. This is the default choice for architectural scenes or any model where shadows help communicate depth.

Focused Accent Scene

Start with a dim Ambient Light for a moody base. Place a Spot Light aimed at the feature you want to highlight, narrow its cone angle, and pair it with a small Point Light inside a nearby recess or lamp for a secondary warm glow. The result is dramatic, localized lighting that guides the viewer's eye.
