Today, when I went into the 'Tools and Plugins' section on FaB, I came across dozens of posts from the same guy: https://www.fab.com/sellers/Specpixel%20Entertainment%20PTY%20LTD

There are one or two AI-generated features being posted—more than 50 in a row.

Just go to the "plugins" section and look at the newest ones; you’ll find that junk there.

I found a problem with Focus logic that made my game go from 80fps to 240fps stable.

If you run through my game (Parry Dungeon) without fighting any enemies, the enemies will Focus you as part of their combat logic, but I stupidly forgot to add ClearFocus logic if you go out of sight. So, if you encounter all the enemies and don't kill them (because killing them deletes them after a bit, which removes the Focus logic cost), you'll have a bunch of enemies that "forgot" you, but are still focusing you. At the end of the game, after encountering 150-ish enemies, you get 240fps standing still, and 80fps moving. This is because those 150 enemies are all still focusing you, so when you don't move, their rotations and body transforms don't need updating. But when you move, they all rotate at once.

Solution: added ClearFocus logic when enemies forget the player. That one node, literally one, saved my soul. I was losing my mind. This issue plagued me for a month. I was adding other features and polishing the game, and have been nearly ready for release for a long time, to move to my next project and keep learning, and I thought this was a side effect of the CharacterMovementComponent, even though I disable them when enemies forget the player.

The key was that UnrealInsights finally made sense. The AIController was calling movement and physics logic. How could the AIController call movement logic? 1. the AI pawn is moving. 2. the AI pawn is rotating, which moves socketed children in the world. The pawn wasn't moving and the behavior trees weren't executing anything because they had no target. That must mean rotation is the answer, and it was. How would an AI rotate without the BehaviorTree executing logic? Something was called before, and keeps executing silently. The treacherous Focus node. I guess having 160 characters rotating in unison may eventually get expensive.

"Vibe your way to $50k: the 2026 Epic AI MegaJam" Really?

As a UE 5 game developer, who participates in the jam every year, my jaw almost hit the floor when I saw this.

I knew Epic was trying to push AI, but this is crazy. Apparently when they first launched the game jam page / info, using AI was a requirement in the rules.

I just feel so embarrassed using Unreal. The optics are terrible. I used to be proud to develop with the engine, but I just find this in such poor taste.

The amount of money they are offering as rewards is also very high for a game jam. Clearly they want to use this as an example of what is possible with AI. I just can't dance with the devil like that, though the money is tempting.

Just released my biggest Kickabout update since launch - the League Update!

Thanks to Epic for their support, will share more on that process soon.

I handled the official HDR implementation for The Sinking City 2, released with Patch 1.1.

Frogwares (the game developer) allowed me to write a technical breakdown covering the implementation, my new Spectre tonemapper, which fixes issues like fire looking different between SDR/HDR, and blue->purple highlight shifts in UE's filmic tonemapper.
Also showcased some DLSS improvements I made.

HDR in Unreal is unfortunately very lackluster out of the box, and has multiple deal breaking issues. We fixed all of them for this.

Can't find a single youtube video explaining how to do it.

I can't figure it out.

AI, can't even figure it out.

Am I missing something, is it possible, as I see there are Spline options in Mesh Terrain Mode, but I have no idea how to turn them into roads, like you would in landscape Mode.

It's in C++ only.

Enemy can see player from back and front with custom back and front distance and angle. Using single UAIPerceptionComponent and single UAISenseConfig_Sight and CanBeSeenFrom function from IAISightTargetInterface.

im missing assets from my vault, i tried downloading them two days ago, and only got around to wanting to use them today and noticed they wernt on my pc so i went to go download them again to find that they wernt in my asset vault anymore.

anyone else had anything similar or have these packs and could try downloading them?

Frank RPG Archer Combo Set

Frank RPG Mage

Frank Slash Pack (11Asset)

and these are just the ones i know about, ive got over 1700 asset packs on my epic account, dont love the idea of losing access to them, and not even knowing unless i manually dig through them all one by one

ive already contacted support to try and get it sorted, hopefully they can sort it out. only thing bothering me now is not knowing if that was the only assets affected

Hi All,

I am trying to recreate the Washington DC downtown inside Unreal Engine, I am using TwinBLD tool from WorldBLD, and I have imported the OSM file and generated a landscape with buildings and few roads, I would like to add parks, lawns, vegetation in the empty spaces. Can anyone guide me on that, like should I create parks and lawns within this Unreal Engine env, or should I individually create them in Blender and import them in UE. ANy suggestions or help would be great.

Also, if anyone has done similiar, please guide me

Following up on my previous Unreal Engine X post, I’ve put together another update to my custom UE5 fork. It’s now based on Unreal Engine 5.8.4, with NVIDIA Flow integration, further rendering work and improvements to the optional ImGui editor interface.

NVIDIA Flow

The main addition this time is NVIDIA Flow, a GPU fluid simulation library for volumetric effects. It uses a sparse 3D grid to simulate fluid motion and combustion.

The integration supports fire, smoke, dust, fog, steam, gas and vortex effects, along with wind and world collision. Collision uses simplified scene shapes, with approximations for more complex geometry.

This short demo focuses on fire: Video Demo

Rendering changes

• Restored legacy ray-traced reflections. Comaprison With HW Lumen
• Added Opacity Micromaps integration. (NVRTX)
• Further Visibility Buffer improvements. In my latest TROPICS test, async mode 2 is slightly faster than the legacy rendering path. This is a result from that particular foliage test, rather than a general performance win.

Engine changes

• Updated the fork to UE 5.8.4, including its Advanced Shader Delivery workflow support.
• Added selected UE6 backports covering CPU performance, Nanite, Virtual Shadow Maps, Vulkan and correctness fixes. Full List Here
• Added plugin module exclusion through Unreal Build Tool.

Editor changes

There’s also more work on XDash and the optional ImGui editor presentation, including the Content Browser, Outliner and Details panel. These views continue to use Unreal’s editing models and commands, with native controls retained where needed. Check here

Experimental multi-adapter support

This remains experimental. It needs more testing to establish which workloads benefit from a second GPU after accounting for synchronization and data transfer costs.

Just wanting to know your thoughts on unreal and if i should use it for a first actual attempt at gamedev, or use something else? Ive heard mixed things about unreal, like to avoid it as a beginner, or you need a pc stolen from nasa to run it. Im unsure how true what i heard is?

The file size and requirements seem a bit daunting?

Mod author here, hope this gives you guys some inspiration / ideas about optimizing your games.

I m using UE5.8 and all the volumetric clouds which i have are like grainy. Is this due to my hardware limits?

Cpu: intel i3 1115G4

Intel UHD 128MB dedicated VRAM (very powerful xd)

8gb ram

I am streaming in a smooth voxel island and surrounding it with the water plugins WaterBodyOcean. The island is fine, but when the island dips in to the water smoothly I get tearing where part of the water mesh is lifted up. Steep angles seem fine for some reason, I assume its sampling the z at given points and misses it.

The island is a series of procedural mesh pieces. I've tried disabling affects terrain, collision, and everything else that seemed likely. No luck.

Does anyone happen to have experience with the plugin and know what to check?

This has been a goal of mine since I started developing tools and working as a freelancer.

Finally managed to release my first game.

Regardless of uncertain feature of video game industry and low sales I'm celebrating this event.

New to using unreal engine, and i have a problem with a mesh flickering/disappearing only in the editor, it started flickering after i reimported it with dialogue, it doesn't flicker in my viewport, only in the mesh editor, and when i try to create a new geometry collection to make a destructible, it justs disappears

I've been developing tools for Unreal Engine multiplayer projects, and I recently combined three of my plugins into a single bundle on Fab. The bundle is called Multiplayer Toolkit for Unreal Engine.

It includes three systems:

Scar Achievements & Platform Services -
Achievements, stats, leaderboards, friends, sessions, cloud saves, rich presence, and platform overlays, with Steam and EOS support.

ScarMultiSession -
Session management, matchmaking, lobbies, and automatic travel into matches, with support for Steam, EOS, LAN, and other Online Subsystem providers.

Scar Core Communication System -
Server-authoritative text chat, voice chat, push-to-talk, quick messages, player muting, voice controls, and live ping.

The reason I grouped them together is that these are three areas developers may need to handle when building an online multiplayer game. I wanted to offer them together rather than make developers find each system separately.

The bundle is available with a Personal license for $24.99 or a Professional license for $39.99.

Here's the full listing:

Since I build these plugins myself, I'm interested in hearing from developers who have worked with Unreal's multiplayer systems. What's been the biggest headache in your multiplayer projects: sessions and matchmaking, platform integration, or in-game communication? I'd especially appreciate hearing what you think is missing from existing tools.

Yes I am aware you can make any genre in Unreal.

I've been making an RTS for a while now and I've noticed that most resources are intended for third person games or first person shooters.

What do You think is the most rare genre of game built in Unreal? Puzzle? Visual Novel?

Had a lot of fun driving through scattered assets and it was relatively simple to set up too! Happy to answer questions here or in the YT comments. Thanks for taking a look, hope it helps.
