How To Use Softbox - Breakdown

Invisible emissive lighting for Lumen. Key, fill, and bounce light with zero visible sources, zero shadow-casting cost — and with Reflection-Safe Mode, zero trace in your reflections.

Every lighting artist hits the same wall: the shot needs more light, but every light you add costs performance, casts shadows you don't want, or shows up in your reflections.

Softbox is the invisible lighting department. Drop in an emissive card and it lights your scene through Lumen GI. No visible mesh, no shadow-casting light cost, and no source to hide in your composition. It's the sourceless lighting technique, productized into a single drag-and-drop actor.

Features

• Sourceless light: emissive meshes drive Lumen GI while staying hidden from the reflections

• Reflection-Safe Mode: removes emitters from Lumen reflections entirely (Hardware RT + Hit Lighting for Reflections)

• Any shape: plane, sphere, cube, or assign any Static Mesh as a light source

• Built for scale: Custom Primitive Data architecture: hundreds of emitters share one material, no draw-call bloat, per-instance control

• Exposure-stable: optional eye-adaptation compensation for visible/debug mode

Requirements: read before buying

• Requires Lumen GI (High scalability or above)

• Reflection-Safe Mode requires Hardware Ray Tracing with Hit Lighting for Reflections; on Software Lumen, emitters light correctly but remain visible in Lumen reflections

• Hidden emitters do not contribute light in Path Tracer renders

• Supported engine versions: 5.6 – 5.7 - 5.8
