Tank Collection - Changelog

Tank Collection - Changelog

Welcome, and thanks for reading. This page will give a brief overview of the feature set for the new Chaos Tank system implemented in the 2.0 update.

Please note: The 2.0 update is for UE5 only. While UE4 versions are in working order, due to the deprecation of physx, updates will no longer be maintained for older versions.

All humble purchases can be redeemed on the Unreal Marketplace: Click Here

This update is live for the entire modern tank collection, while the WW2 tanks are currently in the process of conversion.

Challenger 2

K2 Black Panther

Leopard 2A7


Merkava Mk 4



Type 10

Feature List

1. UV Tracks/Spline Tracks

Tank tracks can now be spawned using two different methods. Traditional UV scrolling, or spline based 3D mesh tracks.

Each tank has it's own set of unique UV and 3D Static Mesh tracks that can be switched between in real time, or disabled depending on performance requirements. Up to 4 unique track segments are included per tank.

2. Track Simulation Improvements

Track simulations are now calculated more accurately, ensuring 1:1 track/wheel/rotor syncronization for convincing and realistic results. The gears of the rear wheels will slot perfectly no matter the situation!

Additional bones have also been added to the skeleton, allowing for realistic track simulation. The tracks will now sag, vibrate, or experience tension based on the movement of the tank. These improvements work for both UV and Spline Based Geometric Track systems!

3. Multiwheel Support

All wheels are now simulated using chaos, providing a significantly more accurate collision response, and a more convincing handling system.

4. Suspension

All wheels and track types have accurate suspension and response, that works with the track simulations. Each wheel will rise or fall, depending on the surface it's moving over.

5. Hydraulics

All hydraulics, springs, coils etc. are rigged and configured in the animation blueprint, providing an additional layer of detail. The wheels move accurately with the rotation of the hydraulic systems.

6. Overhauled Chaos Controller

The overall physics and handling of the controller has been greatly improved. The tanks will now wobble, shake, sway and turn with a weight matching what you'd expect from vehicles of this size.

7. Stationary Turning

Tanks can now rotate on the spot, with convincing wheel and track movement.

8. Weapon Stability Control

There is now a toggle option for turret stability, allowing the user to maintain aim as the tank goes over uneven terrain.

9.  New Skeleton

The skeleton has been reworked for each tank. Bone names are more consistent, with more bones being shared, reducing any additional overhead. Additionally, more components and accessories are now rigged, providing an enhanced visual response, as well as additional track bones for track simulation.

10. Post-Processing Animation Blueprint

Each tank now has it's own post-processing animation blueprint, as well as two detailed and tuned physics assets. This allows for realistic simulations of the tank accessories. Chains will shake, accessories will wobble, cables will sway, and antenna's will bend, all in a convincing fashion, working with inertia for a realistic physical response on each tank!

Additionally, improvements to the weapon system now sends a shockwave through your tank, watch as the accessories of the tank react to each powerful blast from the cannons!

11. Improved Weapon and Aiming System

Sniper-Aim is now included, allowing you to zoom and aim more reliably, as well as some minor updates to the HUD and aiming reticule.

Bullet's and missiles now have impulses on impact, allowing you to blow rigid bodies across the map!

12. Detailed Comments and Descriptions

Each variable and function now has detailed comments, and descriptions, providing you with a better understanding of how the tanks function behind the scenes!
