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.

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.

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

Continuing my journey back at the #gym ! I was still a bit sore from the last weekend so I changed it up. I'm still running light #weights but adding extra #reps until I feel a bit more in tune with my body. #OOTD #gymfit #blonde #ponytail #fitnessjourney #buildbackbetter

day 608: ! built a fake real-time GI system for my game and it cost almost nothing to run! The warm sunset light wrapping under the car is not baked, not a probe volume, not a reflection capture. here is how it works 🧵 #buildinpublic #indiegamedev #unity3d

🚨 S&P 500 VOLUME IS DISGUSTING 🚨 The price remains high - but nobody's really buying it Look at the left side of this chart - that's exactly what happened in early 2025 Quiet rally with no real volume. Then volume returned, triggering a major crash For now the right side is printing the same sequence - and we're sitting right where volume is starting to pick up again This is just a theory, not a fact, but you should still be prepared for it NOTIFS ON!

My upcoming game has a Steam page now so that folks can wishlist it: It's called GIANT ROBOT GAME. Here's the first trailer, for which I recommend sound on and volume up:

Candles They are sending billionaires and pop stars into space while the planet burns and Americans ration their insulin. There are companies marketing AI lovers to lonely people and harvesting their data. Last night Israel bombed a tent camp in Gaza, and women and children burned alive. This is a strange, dark place. Strange, dark times in a strange, dark world. Light a candle for those who have died. Light a candle for those who are dead inside. Light a candle for those with algorithms in their eyes. Light a candle for those with AI in their souls. Light a candle for the screaming red children. Light a candle for the silent gray children. Light a candle for the Great Pacific Garbage Patch. Light a candle for the songs of the whales. Light a candle for the hearts like cast lead. Light a candle for the hearts like wallaby roadkill. Light a candle for the hearts like incense cathedrals. Light a candle for the hearts like wet skies. Light a candle for the eggs in our chests. Light a candle for the seeds in our heads. Light a candle for the mushroom cloud on the horizon. Light a candle for the sleeping Buddhas. I stand slack-jawed and dry-mouthed at a world I do not understand, hurtling toward a future I do not recognize. Firelight dances on my wall from the candles, or maybe from Gaza, or maybe from the biosphere, or maybe from just beneath my skin. Reading by Tim Foley.

🤘Drift Boost Chomps! Added most of the math for the Drift boost calculation, but needs some tweaking and visual indication, right now it falls a bit flat without it, but the logic is there so thats a start! The bar on the left indecate boost charges #gamedev #ue5 #prototype

👀Eyes now look in the direction of your decired moving direction and Blinks! 🛹Plus early preview of Grinding! it is still a bit wonky but it's at a place where it works fairly well and I just need to tweak, iron it and Juice it up! #gamedev #solodev #ue5 #WorkInProgress

THE S&P 500 RALLY HAS NO BUYERS I know what you're thinking - "but the price is going up" That's exactly the trap When the market rallies on dead volume, it's not buyers pushing it higher It's the absence of sellers. Two completely different things Here's how it works: Step 1: low volume rally - you're looking at it right now Step 2: volume returns, but it's not buying Step 3: the part that makes you wish you sold at step 1 I'm not in this rally. And I'm not changing my mind until volume confirms it FOLLOW + NOTIFS ON!

"It's a dark time right now, but hopefully I can shed a little light for them and be a little bit of hope": Jonathan McComb lost his family in a 2015 Texas flood. Now he's a volunteer with Texas Search & Rescue helping those affected by the disaster in Kerr County.
