About this mod

luum is a lighting mod based on emulating a real-world cinema camera, using real-world film techniques to simulate an ARRI Alexa 35 camera when used in tandem Realcolorr. luum has weather probability rebalances, meticulously tweaked film grain to match sensor noise, enhanced chromatic aberration, subtle bloom, and perfect eye adaptation settings.

Permissions and credits
luum: A cinematic lighting mod

luum is a very work-in-progress lighting mod which aims to recreate a real-life ARRI Alexa 35 camera system, as well as overhaul both PT and raster lighting systems to become more lifelike.

  • Enhanced chromatic aberration
  • A reasonable amount of aberration to add more life to the image while keeping its effect subtle, blending into gameplay seamlessly.

  • 'Goldilocks' bloom
  • The just right amount of bloom, in order to reduce blur, but at the same time, keeping the image punchy.

  • Tweaked, sensor noise-like, film grain
  • A bayer-derived and resolution dependent film grain settings in luum make film grain be just like camera sensor noise, with luminance bias to the correct areas and accurate color deviation.

  • Perfect eye adaptation
  • Passive settings make eye adaptation correctly lower exposure when important areas are bright, and increase exposure when most of the image is dark, just like your real eyes.

  • Overhauled color
  • Through using Realcolorr 2.0.0+, luum achieves raw and cinematic color grading.

Just like all of my other mods, image and video permissions are open. Also, since this is a open alpha, go ahead and put your suggestions in the forum post. I also encourage you to use the bug tracker.

Color science
luum uses ARRI technical documents to approximate an ARRI Alexa 35 camera, with ARRI texture specifications serving as reference for sensor noise emulation, as well as LogC documentation informing the development of Realcolorr 2.0.0+.

luum is really only half of the whole look when not used with Realcolorr 2. luum, while sporting more accurate and noticeable global illumination, depends on the high quality color Realcolorr 2 gives it.

Lighting changes
luum targets both PT and raster, but PT is what is used in screenshots. PT with luum gets a more intense amount of diffuse and specular light bouncing that simply isn't present in vanilla, causing its low bounce number to cause shadows to not get the necessary amount of light. With alteration of both light intensity of the sun, sky lighting, and PT settings, luum achieves more realistic light and shadowing.

By the way, if you want any further details, feel free to ping me at ´╗┐null ?#0395, or talk on the luum thread in #showcases on the. . .

By the way, if you're all the way down here, consider endorsing the mod. It really helps it out.
Thank you for reading, and have a nice time in Night City!
