A motorbike with working suspension

A motorbike with working suspension, a spinning chain, and suspension force applied during braking. Both the motorbike and character use Control Rig, allowing the bike to turn and the rider’s foot to come down when stopping. I’ll be working on the tutorial soon, so stay tuned.

Unreal Engine 5.6: Add a Drivable Vehicle to Game Animation Sample

In this tutorial, we are going to add drivable vehicles from the Vehicle Template to the Game Animation Sample. The character will be able to enter the vehicle when overlapping with the vehicle's box collision.

3D Modeling Web go live.

After two months of development, I’ve published this 3D viewer web app on kokraf.com. I believe the web app ecosystem can offer an experience and level of technology that downloadable apps often can't match.

Your suggestions are truly appreciated—feel free to share them in the comments! This app is on a path to becoming a unique, one-of-a-kind 3D modeling tool, not just another clone.

If you'd like to support its deve...

[Project File] Destructible Vehicle Project from City Sample Updated to UE 5.6

This post contains a link to the project file for download.
I updated our destructible vehicle project to Unreal Engine 5.6. I included all 13 vehicles from the City Sample in this project. The total project download size is 5.39 GB. Vehicle movement, vehicle deformation, and the sound system are all replicated. The project has already been successfully built, packaged, and tested on Windows.

🤩 I included all 13 vehicles from the City Sample in this project. The total project download size is 5.39 GB. I redesigned the enter and exit vehicle system to be replicated. Vehicle movement, vehicle deformation, and the sound system are all replicated. The project has already been successfully built, packaged, and tested on Windows.
This is the result of months—and years—of breaking down and rever...

[Project File] Unreal Engine Vehicle Possession & Replication (Multiplayer)

This post contains a link to the project file for download.
In this tutorial, we will replicate vehicle control in a multiplayer network. You’ll learn how to possess and unpossess a vehicle, prevent characters from entering vehicles that are already controlled, and use Multicast and RepNotify to replicate character location across the network.

This post contains a link to the project file for download.
In this tutorial, we will set up a Traffic Manager to spawn vehicles and assign target locations for each one. We’ll use Unreal Insight to analyze performance issues and implement multithreading to optimize key functions. Additionally, we’ll create a Vehicle AI Component parent class to manage AI behavior efficiently. By the end, you’ll have a more optimized and prepared for traffic system in Unreal Engine.<...

[Project File] Windwalker Echo Locomotion Updated to UE5.5

This post contains a link to the project file for download.

You might not recall this animation locomotion, but it features the most beautiful turning animation I've ever seen. The turning and transitions are incredibly smooth, and it's all done purely through the animation graph. I've extracted it for the default mannequin so you can easily use it in your project. With this update, it feels fresh and new.

[Project File] Unreal Engine AI Vehicle Tutorial 16: Offroad Vehicle AI

This post contains a link to the project file for download.

In this tutorial, we will create a vehicle AI capable of driving off-road on various terrains. To achieve this, we'll use the A* algorithm with a free step to perform line traces of neighboring points to determine the landscape's height. This allows us to generate a path with the lowest slope and the shortest distance to the target without searching boundary.

Vehicle AI Terrain Pathfinding

Our Vehicle AI can navigate uneven terrain, both on and off roads. The free-step A* algorithm allows it to find the closest path with the lowest slope to reach any target location.

Edit Landscape in C++

After a week of dedicated effort, I successfully developed a C++ function to deform or raise the landscape at a specific world location. This function is designed to procedurally adjust the terrain, making it suitable for our road network tool. The WorldLocation parameter defines the precise point in 3D space where the landscape modification takes ...
