with basic working 3D coordinates, physics, and collision. there was absolutely zero reason to do all this

i made a point and click/pet simulator thing in unreal's UMG (these are all just UI elements lol) #unrealengine #gamedev

custom movement in unreal is fun

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

grumbo! (Happy! the Hippo) @grumbo.dev · 04/03/2025

works for point lights too (this one isn’t animated but you get the idea)

grumbo! (Happy! the Hippo) @grumbo.dev · 04/03/2025

my plugin’s custom lights support colored/animated materials now lol #unrealengine #ue5 #gamedev

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tim sweeney watching in horror as i go out of my way to make his billion dollar, cutting edge game engine look as outdated as possible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

it’s realtime too, running at 120fps atm. dynamic shadows tank the performance but i haven’t really started optimizing that yet, so 🤞

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

grumbo! (Happy! the Hippo) @grumbo.dev · 04/12/2024

need to figure out the flickering (and dozen other issues) but my custom shadow mapping in ue5 kinda sorta works :)))

grumbo! (Happy! the Hippo) @grumbo.dev · 03/12/2024

does anybody else’s dog do this 😂😂

grumbo! (Happy! the Hippo) @grumbo.dev · 02/12/2024

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

hoping by the end of this to be able to recreate the look of 90s prerendered graphics in realtime

grumbo! (Happy! the Hippo) @grumbo.dev · 01/12/2024

slowly starting to get realtime shadows working for my phong and gouraud shaders in UE5! no built in lighting stuff here :) #unrealengine #ue5

grumbo! (Happy! the Hippo) @grumbo.dev · 30/11/2024

it took SO much time to figure this out but i finally got basic realtime shadows working with my custom vertex lighting in unreal :)) (there’s no actual UE lighting being used here) #ue5 #unrealengine

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
