LogInThe creator plans to share the system as a downloadable asset.
Indie Developer and Unreal Engine enthusiast known as grumbo continues working on Happy! the Hippo, an upcoming 3D platformer featuring "overpowered movement" and "PS2 jankiness", presenting a fantastic custom-made lighting system developed for it in Unreal Engine 5.
Developed with C++ in the unmodified version of the engine, the system enables its creator to set up striking 90s-style 3D renders, featuring phong shading and dynamic shadows achieved through custom light classes and a subsystem to manage them, which store all the lighting data in a texture and read it within the material. Going forward, grumbo aims to release the system as a downloadable asset and share an in-depth breakdown for those who'd prefer recreating it themselves.
"If you're just talking about the actual lighting data and not the shadow maps, it's a single render target," the developer explained. "It's resized dynamically whenever a light is added or removed from the scene – can't remember the exact size off the top of my head, but each light takes up one column of 3-5 rows of pixels. One for the light color/intensity, one for the location and radius, one for the shadow map index, etc. Spot lights and Rect lights use a few more rows since they have some extra data (direction, angle, etc.), so you could have a thousand lights in the scene, and at most it'd be a 1024x5 texture."
