Senior Lighting Artist Karim Yasser has created an Unreal Engine 5 plug-in that enables users to paint light and shadows in a non-destructive, real-time environment. The tool is designed to bypass existing lighting limitations and accelerate professional creative workflows.
Why it matters
This innovation aims to solve significant lighting bottlenecks in game development by allowing artists to manipulate shadows as easily as they would in 2D image editing software. By storing lighting data in textures, it provides developers with greater granular control over their virtual environments.
The tool supports both Gobos and Spot Lights for local and global illumination across Unreal Engine 5 scenes. Users can utilize seven distinct options, including Gradient, Noise, and Flatten, to manipulate light interaction.

He is a Senior Lighting Artist at MBC Game Studio who designed the new lighting plug-in.
The details
The plug-in functions similarly to 2D drawing software, enabling users to paint lighting effects that are then stored directly within textures. This non-destructive process supports various light types, helping artists maintain complete control over their work without re-rendering entire scenes.

The Tech Race
The emergence of real-time painting tools represents a shift toward more intuitive, artist-led development within Unreal Engine 5. It positions this new software as a direct challenge to more traditional, slower rendering workflows that previously limited creative flexibility.
Developers and artists can anticipate significantly faster production cycles when this plug-in becomes available. By enabling real-time adjustments, the tool reduces the need for constant, time-consuming re-bakes of complex lighting environments.
The takeaway
This tool highlights a growing movement to make game development workflows more fluid and responsive to artist input. Professionals can look forward to future updates as the developer plans to integrate additional custom shapes into the system.
