i made light booleans for my stylized lighting plugin! it is very nice being able to exclude/include certain lights in certain areas (and cast basic shadows) #unrealengine5 #ue5

added cel shading to my custom lighting plugin for UE5 :) it’s handled in the actual lighting calculation, so it works properly with lighting and shadows (no post processing except the outlines). still WIP but really happy with it! #unrealengine #ue5 #gamedev #gameart

RIP david lynch :( i wouldn't be making the stuff i'm trying to make without his work i never finished it but here's some screenshots from a project a few years back when i was blatantly ripping off his stuff one of the few people to actually change the way i see art as a whole. heartbroken :(

tim sweeney watching in horror as i go out of my way to make his billion dollar, cutting edge game engine look as outdated as possible

the dithering wasn’t working properly here but just pretend it was

this is an actual raycast renderer (eg wolfenstein) running in the unreal ui lol

grumbo! (Happy! the Hippo) @grumbo.dev · 25/12/2024

i finally got my custom 90s pre-rendered graphics-style lighting/shading system for UE5 working, i’m so happy yall have no idea. first test scene with it, no default unreal lighting here :)) #unrealengine #gameart #ue5 #gamedev

pov: you are point light being dragged around the scene to test the most unoptimized, barely functional shadow mapping known to man

i can’t stop thinking about this youtube comment comparing my game to (i think) gummy bears magical medallion for wii. i’m not upset, i’m just both scared and impressed they can seamlessly reference gummy bears magical medallion like that

hi butterfly app people :) i’m a solo indie dev working on Happy! the Hippo, a (100% normal) 3D platformer that embraces the jankiness of early 2000s PS2 games. if you like sonic adventure/spyro/pacman world, you might find it kinda neat! check out the demo on steam or wishlist it if you want ❤️
