I've recently released the Light Propagation Volumes (custom GI plugin) for #UE5 LPV is an algorithm of resolving the diffuse light bounce from the perspective of the sun in world space (firstly introduced in 2009 by Crytek). It's non-temporal, performant and lightweight.

Continuing my custom GI experiments - here's a "Light Propagation Volume" prototype in #UE5 (from a plugin)! It's unoptimized right now, it has just a single volume and the reflected light looks a bit strange, but still!

I got something crazy for today - custom GI from a plugin in #UE5!! This is super rough and unoptimized sketch, but it's already faster than Lumen, though of course it's muuuch less accurate. Here I'm just imitating Large Scale AO using Global SDFs, no sun light bounces yet.

Another thing that is going to be released with next version of VRC Light Volumes, is an in-game debugger tool! You'll be able to preview every volume, voxel, and point light. Works in any world that supports VRC Light Volumes.

I've done some graphics research lately and been tinkering with a new voxel renderer. It's pretty different from the one in Teardown, focusing heavily on GI. There are no explicit light sources in this scene (except for the sun), just emissive voxels.

The gift of the Sunflower. Always give them in pairs. For in the light of the sun, they seek the sun. But in the darkness, they seek light of each other. If you ever feel alone, it is my wish someday I could gift you a pair of sunflowers. A reminder that you have—light.

Tariq has recently become christian, and leaving darkness to find light of Christ. ✝️🙏 "I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life." John 8:12.

This isn't an expanding star: this is a light echo! In this time-lapse sonification, a pulse of light from the star V838 Monocerotis gives the illusion that the surrounding dust is expanding. In reality, it's just the light from the star's flash reaching dust farther away.

Trump stories: “In the midst of darkness shines a great light!” Like I've always said, Trump is the worst racist in the world.

My Source 2-like probe system + light baking for UE5 is pretty much done now fully. As seen in the video, with the right volume setup you can have super thin walls without light leaking. Plugin releasing in like a week, after my vacation. #UnrealEngine5 #UE5 #GameDev

Professor Brian Cox explains using a simple light clock, time is not absolute. Because the speed of light remains constant, a light beam in a moving clock traces a longer, diagonal path from an outside observer's perspective, proving that moving clocks run slower and time literally bends to the speed of the observer. This reveals a mind-bending reality: if you journeyed through space at 99.94% the speed of light for ten years, you would return to an Earth that had aged 29 years; making you a literal time traveler into the future.

Yesterday I had the privilege of joining wonderful friends in Kansas City for a Light the World Giving Machine event. What an inspiring reminder of the power of simple acts of kindness! Last year, more than 850,000 people visited Giving Machines around the world, purchasing 450,000 items to bless those in need. These efforts reflect the heart of the Light the World initiative, which is rooted in the Savior’s words: “I am the light of the world.” His light was never meant to be admired from afar—it was meant to be shared. Thank you to everyone who continues to bring Jesus Christ’s light to the world, one act of love at a time.

If the moon's light is reflected sunlight, then how come moonlight is measurably COLDER than the shade during a full moon? Here's direct FLIR camera data proving this. (I've also tested it myself with an infrared thermometer; visit my website for the full experiment report: It's almost like our entire world, from the masculine/feminine, to good/evil, to the sun/moon...are all intelligently-designed upon the basis of POLARITY ☯️ The Sun is a light that gives warmth and sanitizes, the Moon is a light that gives cold and putrefies. (Yes, the moonlight has also been proven to break down/decompose organic matter it's exposed to, the exact OPPOSITE of the sun) Genesis 1:16: "And God made two great lights; the greater light to rule the day 🌞, and the lesser light to rule the night 🌝" If you haven't already...it's time to throw away all of your Mossad Science™ textbooks, along with everything you've ever read in them. You've been lied to since birth about your entire reality.

Bursting Selenite "Flower" from Winnipeg, Canada 🌼 This Selenite glows under UV light and shows an amazing phenomenon called phosphorescence. The energy from the light gets stored in the crystal and slowly dissipates after the light is removed as shown at the end of the video.

Visitors to Times Square were in for a surprise on Nov. 27 as its famous billboards became a larger-than-life tribute to the true reason for Christmas: Jesus Christ. The billboard takeover at Times Square in New York City was part of Light the World, an annual movement to bring people from all over the world together to share the light of Jesus Christ during the Christmas season. The beautiful nativity scene that emerged from the blackout was a tender reminder of the Savior’s birth and why we need His light and love in our lives.

Here is a full showcase of my custom Source 2-like light baking and probe implementation for Unreal Engine 5. Features showcased: - Volume based probe system (full density control, fade between volumes with a volume fade slider, automatic volume priority and custom priority overrides) - GPU Lightmass with expanded features like a custom denoiser and overall QOL (like a bake volume which only bakes objects inside the volume for fast prototyping) - Custom Box Capture implementation to make it easier to use (basically just a custom way of scaling the box capture component since its so annoying) - A custom fullbright viewport option for easier map editing (without having to get visual clutter in the way) Will eventually release on FAB as a plugin for UE 5.7. Everything is running inside an Epic Launcher Downloaded version of UE5 in this showcase. #UnrealEngine5 #UE5 #GameDev
