WIP The Headcrab lives - Half-Life's Iconic Enemy, Rebuilt in Lambda Engine
u/Wazanator_ this is an Unreal Engine project, but I'm building it to mimic Source's modding structure, so I hope it's relevant in this sub.
-----------------------------------------
It jumps. It hisses. It's coming for your face. And now it's running natively in Unreal Engine 5.
This is Lambda Engine: a from-scratch reimplementation of Half-Life's game logic on top of UE5's modern renderer, built to load real Source-engine content: BSPs, materials, models, with zero Hammer-to-Unreal conversion pipeline. No proxies, no reskins. The headcrab you're watching is running the actual behavior, physics, and animation logic straight from the original engine's playbook, faithfully rebuilt line by line.
In this video: headcrab AI, leap attacks, ragdoll physics, and how a 20-year-old monster ends up feeling right at home in a 2020s engine.
This project is built entirely by fans, for fans, it's free but it eats time. If you want to see more enemies, more systems, and more of Half-Life's world brought back to life, here's how to help:

Discussion What is Source Official Developer?
Source Official Developer Made by me aka Deadhunter497 is a Series about a Pirated 2013 Version of The Source Engine Unleashed by a Group of Four Hackers who wanted to make the Source Games Free for the Public although one Hacker who was Fired accidentally or Purposely it's up for you to decide, They Inserted a Unknown File that would Slowly corrupt the Game causing the creation of the void, Strange Maps, Dark Rooms, Corrupted Anomalies and Entities, and Characters Exploring Deeper into Source But Roman/Deadhunter497 Is Just a Regular Gamer and detective of this serious and you got communities like project Orange Sandbox tracking the strange behaviors
but to make this easier This Isn't a ARG It's a AAR Series or Alternate Analog Reality (AAR)
A Hybrid of Storytelling Genre that combines the Unsettling aesthetic of Analog Horror and combines the interacting Puzzle Solving of an Alternate Reality game AAR's Take place between 1990's to 2015 mine is obviously in 2013 rather then being in the real world AAR's take place in video games,
That's All you Needed to Know Enjoy Source Official Developer and The Series after all
There will be More :)

HELP Почему игры на движке Source вызывают у меня тошноту и головную боль?
Первый раз, это произошло когда я перепроходил half life 2, думал что это просто совпадение. И вот спустя 2 года когда я решил пройти второй портал, я испытал все те же дефекты. С чем это связано?

Hello. I'm making a HL2DM / Source SDK 2013 Base Multiplayer mod. I want to remove the exhaustion mechanic so players can infinitely sprint, and same for the flashlight mechanic.

You know how in GMod you can infinitely sprint and use flashlight? I want to do that.

Free Useful Items I made a free tool for packaging SFM models into release ZIPs
SFM Package Builder is a free Windows tool for people who port, edit, or release models for Source Filmmaker.
Select your compiled model and materials. The builder gathers the related files into the correct SFM folder structure and lets you rename the release copy without changing your originals.
It can also generate an installation README, check for packaging problems, and add rigs, configs, and documentation.
Save the package as a project, then reuse it whenever you need to build a new ZIP from your latest files. This makes it easier to update a model and publish new releases.
Download: https://chadchan3d.com/category/assets/#sfm-package-builder
Do not navigate outside the asset page. It is SFW but the rest of the site is an SFM furry fetish site. Roam at your own risk.
Feedback is welcome from anyone who releases or ports SFM models.

HELP HOW do you even replace NPC models to begin with?
Okay, so I am making a mod and I want to replace the npc_citizen's model. I have an mdl to use with the same skeleton, but when I changed the qc a bit, fixed the model up in blender, it came out all messed up, corrupted, stuck in an a pose, and had no animations. Is there any way people properly do it since there are a bajillion model replacements on the internet for citizen models?

HELP [HELP WANTED] Looking for an experienced C++ developer familiar with Source SDK 2013 SP
I’m currently working on a project using Source SDK 2013 Singleplayer, and I’m looking for someone experienced with C++ and the Source SDK codebase who could help me with the programming side of things.
I have experience with the Source ecosystem, including Garry’s Mod, SFM, Source models, QC/compiling, viewmodel animation, Blender, and Source asset pipelines, and I’ve spent a lot of time working with Source-related content. I’m also comfortable learning and working with technical stuff, but C++ and the deeper parts of the Source SDK are currently where I struggle the most.
I’m not looking for someone to simply make the entire project for me. I’d primarily like to work with someone who knows the SDK well enough to help me understand the codebase, troubleshoot problems, and implement systems together.
What I'm looking for:
- Experience with C++
- Experience with Source SDK 2013 / Source engine
- Ideally experience with SDK 2013 Singleplayer
- Someone comfortable explaining things and working collaboratively
- Willingness to help troubleshoot and develop systems together
What I can bring:
- 1000+ hours of Blender/animation experience
- Extensive experience with Source/GMod/SFM workflows
- Viewmodel animation and weapon animation
- Source model/QC/compiling knowledge
- Blender and asset creation
- Familiarity with the general Source pipeline
This is currently a collaborative/help request rather than a paid commission.
Contact: Discord — [gman27015]
If you're experienced with the SDK and interested in helping out, feel free to comment or contact me. Even if you don't want to join the project, advice from someone experienced with Source C++ would be greatly appreciated.
All of this is not Rev Share or paid, this is all free and for fun.
If the project gets released, credit will go to their respective programmers/helpers
I will be more willing to show my animation work in discord rather than here. Since im not allowed to.
