Notes[]
- The lighting engine was overhauled in 0.5.2.0-b84a, making it impossible to determine the exact radius of light sources due to the addition of intensity and directionality.
Trivia[]
- Internally Core Keeper is a 3D game, which is how many of the advanced lighting techniques are achieved.
A screenshot of the game with the camera's position adjusted.
History[]
- 0.7.4.2-7883: Fixed a bug where many light sources would get completely disabled on low light quality settings.
- 0.5.2.2-a842:
- Lit Floor tiles no longer block other emissive light sources like Glow Tulips.
- Light colours are now correctly converted to linear space when gathering light data.
- 0.5.2.0-b84a: Completely reworked indirect (bounce) lighting. Light now spreads further and takes surface color into account, resulting in softer, more saturated dynamic lighting.
