At its core, set.a.light 3D is a lighting simulator and previsualization tool. It allows you to build a 3D studio from scratch, place virtual models, and experiment with an extensive library of lights and modifiers. The software uses real-world light physics to accurately simulate how shadows, reflections, and light fall-off interact with subjects and backgrounds.
Beyond just lights, the software allows users to build simple sets. You can construct walls, place furniture, and position props to create a "digital twin" of the shooting location. It also supports importing CAD files and 3D models, making it easy to integrate with existing pre-production workflows. setalight3d
