I'm pleased to announce that Ultra Engine SDK Early Access is now available. Four years ago, I set out to solve the performance problems I was seeing while working on virtual reality projects at NASA. Ultra Engine is the product of a lot of intense research and development during which I invented a new architecture designed for the way modern graphics hardware works. The results exceeded my wildest expectations, providing Ultra Engine with order-of-magnitude faster rendering performance than Lea
A few years ago, some folks at NASA asked for my help with some VR projects they were working on. They had switched to Leadwerks and were getting better performance with that, but it still wasn't fast enough for what they were trying to do. I flew from California out to Goddard Space Flight Center to meet with them. When I saw what NASA was doing with my software, my jaw hit the floor.

Ultra App Kit 1.1 is now available on our website and on Steam. This free update brings cross-platform development to our fast resolution-independent GUI toolkit. To download the new installers, click on your account purchases.
In addition to Windows, Mac and Linux are now supported, which means you can code once and compile everywhere to easily create cross-platform GUI applications.
Builds on Linux use minimal dependencies and will work on virtually any distro without any additional
Built to power a new generation of game development tools, Ultra App Kit provides an easy-to-use C++ programming SDK for creating desktop GUI applications.
Unlike other alternatives like Dear ImGui, the Ultra App Kit GUI renders in retained mode rather than immediate mode, and is specifically designed for desktop GUI applications. This makes applications snappy and responsive when resizing or refreshing a window.
DPI scaling is baked into the design for resolution-independent

We're approaching the end of a loooooooooong cycle of research and development...several years, in fact, have been spent building the fastest game engine in the world. A great game engine needs a great user interface, and Ultra App Kit provides exactly what we need. This will provide the backbone of o
Leadwerks Game Engine 5 will be backwards-compatible with asset file formats used in version 4. In addition, we are adding support for glTF 2.0 (GL Transmission Format), a new open-spec model format from Khronos with support for skinned animation and PBR materials. glTF will be our main 3D model format, for both development and final published models.
What's so great about the glTF file format?
Documented and Human-Readable
Unlike the "black box" FBX file format, which can only be re
The GMF2 file format provides the fastest possible load times for 3D models. A preliminary specification and SDK for loading and saving files in the GMF2 file format is now available on GitHub here:
A Quake 3 MD3 model loader is included as an example.
Leadwerks Game Engine 4.6 is now available on Steam! This free update adds Steam peer-to-peer networking, lobbies, voice chat, and more. A new multiplayer game template makes it easy to get started with your own multiplayer games, adding new depth and interactivity to the fun.
We've also added over 100 bug fixes, making this the most stable release ever to build your game on!
New parameters for bet
A new update is available for Leadwerks Game Engine 4.6 beta. This fixes many bugs.
Slow kinematic joint rotation
Heightmap import flipped
Map switching crashes in VR
Project Manager cancel button bug
The Zone DLC map failing to load
Ball joints not working
Take a look at the bug reports forum to see all the recent fixes in the engine and documentation.
This is a full update, with new builds for Windows and Linux, for C++ and Lua games. You
The beta branch on Steam is now updated. Version 4.6 introduces peer-to-peer multiplayer capabilities with a new multiplayer game template. Check out the new features in the documentation:
The physics library is updated to the latest version of Newton.
The editor has some enhancements as well:
Model editor view range is calculated from model extents, so if you load a model that is huge it won't be invisible.
Model editor displays n
Here's a look at the new vehicle system that is being developed. The API has been simplified so you simply create a vehicle, add as many tires as you want, and start using it. The AddTire() command now accepts a model and the dimensions of the tire are calculated from the bounds of the mesh.
int AddTire(Model* model, bool steering=false, const float spring=500.0f, const float springrelaxation = 0.1f, const float springdamping = 10.0f);
void SetGas(const float accel);
I'm wrapping up the new multiplayer capabilities for Leadwerks 4.6, and I am very excited about what this offers developers.
We saw previously how the lobby system is used to create or join games, and how to retrieve Steam IDs for messaging. Once we have joined a game we can start sending messages with the P2P::Send command, which includes a few overloads:
static bool P2P::Send(uint64 steamid, const int messageid, const int channel = 0, const int flags = 0);
static bool P2P::Send(uint64
The next update will include a new networking system with built-in voice chat for multiplayer games.
Voice communication is built into your game and can be enabled simply by turning it on when a specific key is pressed:
You can selectively filter out users so your voice only gets sent to your own team or to a specific player:
void Voice::SetFilter(const uint64 steamid, const bool state)
When another player sends their voice
The new Lobby system in Leadwerks 4.6 allows you to create a public listing of your multiplayer game for others to join. This uses the Steamworks library. You can tap into the Steamworks lib by piggybacking on the default "SpaceWar" example game, which uses the Steam app ID 480. This is set up by default when you create a new Leadwerks project.
Now you might think of a lobby as a place where people hang out and chat before the game starts. You can treat it like this, but it's best to keep t
A new build is available on the beta branch. This changes the model picking system to use a different raycasting implementation under-the-hood. Sphere picking (using a radius) will also now correctly return the first hit triangle. You will also notice much faster loading times when you load up a detailed model in the editor!
Additional parameters have been added to the Joint::SetSpring command:
void Joint::SetSpring(const float spring, const float relaxation = 1.0f, const float damper =
A small update has been published to the default branch of Leadwerks Game Engine on Steam. This updates the FBX converter so that the scene units (meters, feet, etc.) are read from the file and used to convert the model at the proper size. Previously, the raw numbers for position, scale, and vertex positions were read in as meters. The new importer also supports both smooth groups and per-vertex normals, so models can be imported more reliably without having to recalculate normals.
An update is available for the new Turbo Game Engine beta.
Fixed compiling errors with latest Visual Studio version
Fixed compatibility problems with AMD hardware
Process is now DPI-aware
Added high-resolution depth buffer (additional parameter on CreateContext()).
Subscribers can download the new version here.
TLDR: I made a long-term bet on VR and it's paying off. I haven't been able to talk much about the details until now.
Here's what happened:
Leadwerks 3.0 was released during GDC 2013. I gave a talk on graphics optimization and also had a booth at the expo. Something else significant happened that week. After the expo closed I walked over to the Oculus booth and they let me try out the first Rift prototype.
This was a pivotal time both for us and for the entire game industry. Mobi
The Turbo Game Engine beta is updated! This will allow you to load your own maps in the new engine and see the speed difference the new renderer makes.
LoadScene() has replaced the LoadMap() function, but it still loads your existing map files.
To create a PBR material, insert a line into the material file that says "lightingmodel=1". Blinn-Phong is the default lighting model.
The red and green channels on texture unit 2 represent metalness and roughness.
The beta branch has been updated. The following changes have been made:
Rolled beta branch back to release version, with changes below.
Added new FBX converter.
Fixed Visual Studio project template debug directory.
Fixed Visual Studio project template Windows Platform SDK version problem.
If everything is okay with this then it will go out on the default branch soon.
