Creating hills + terrain + paint from script

Example:   I could strangely find nothing about terrain generation from script except for LE5...  So here is an example that will run with LE4.6 on how you can generate 2 little  hills on a terrain and paint it from script. Can be usefull for games with random generated landscape. The script I modified is from here: https://www.leadwerks.com/community/topic/15715-minimap-generator/?do=findComment&comment=104697 So first install the minimap shader to run this:

Leadwerks 5 Feature Spotlight: glTF Models

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

Voxel GI: GPU Acceleration, corrected bounces, and reflections

I've moved the GI calculation over to the GPU and our Vulkan renderer in Leadwerks Game Engine 5 beta now supports volume textures. After a lot of trial and error I believe I am closing in on our final techniques. Voxel GI always involves a degree of light leakage, but this can be mitigated by setting a range for the ambient GI. I also implemented a hard reflection which was pretty easy to do. It would not be much more difficult to store the triangles in a lookup table for each voxel in order to

Voxel GI: Light Bounces

I implemented light bounces and can now run the GI routine as many times as I want. When I use 25 rays per voxel and run the GI routine three times, here is the result. (The dark area in the middle of the floor is actually correct. That area should be lit by the sky color, but I have not yet implemented that, so it appears darker.) It's sort of working but obviously these results aren't usable yet. Making matters more difficult is the fact that people love to show their best scr

Voxel GI: Colors and Fast Downsampling

The polygon voxelization process for our voxel GI system now takes vertex, material, and base texture colors into account. The voxel algorithm does not yet support a second color channel for emission, but I am building the whole system with that in mind. When I visualize the results of the voxel building the images are pretty remarkable! Of course the goal is to use this data for fast global illumination calculations but maybe they could be used to make a whole new style of game graphics.

Vulkan Voxels

I have resumed work on voxel-based global illumination using voxel cone step tracing in Leadwerks Game Engine 5 beta with our Vulkan renderer. I previously put about three months of work into this with some promising results, but it is a very difficult system and I wanted to focus on Vulkan. Some of features we have gained since then like Pixmaps and DXT decompression make the voxel GI system easier to finish. I previously considered implementing Nvidia's raytracing techniques for Vulkan bu

Advanced Lua Debugging

I've had some more time to work with the Lua debugger in Leadwerks Game Engine 5 beta, and it's really amazing.  Adding the engine classes into the debug information has been pretty simple. All it takes is a class function that adds members into a table and returns it to Lua. sol::table Texture::debug(sol::this_state ts) const { auto t = Object::debug(ts); t["size"] = size; t["format"] = format; t["type"] = type; t["flags"] = flags; t["samples"] = samples; t["faces"] = faces;

Debugging Lua with Visual Studio Code in Leadwerks Game Engine 5 Beta

Leadwerks Game Engine 5 Beta now supports debugging Lua in Visual Studio Code. To get started, install the Lua Debugger extension by DevCat. Open the project folder in VSCode and press F5. Choose the Lua debugger if you are prompted to select an environment. You can set breakpoints and step through Lua code, viewing variables and the callstack. All printed output from your game will be visible in the Debug Console within the VS Code interface. Having first-class support for

Leadwerks Game Engine 5 Beta Updated with Pathfinding, Bone Attachments, and more...

A new update is available for beta testers. This adds navmesh pathfinding, bone attachments, and the beginning of the Lua debugging capabilities.New commands for creating navigation meshes for AI pathfinding are included. NavMesh Pathfinding In Leadwerks Game Engine 5 you can create your own navmeshes and AI agents, with all your own parameters for player height, step height, walkable slope, etc.: shared_ptr<NavMesh> CreateNavMesh(shared_ptr<World> world, const float wi

Bone Attachments

In Leadwerks Game Engine 4, bones are a type of entity. This is nice because all the regular entity commands work just the same on them, and there is not much to think about. However, for ultimate performance in Leadwerks 5 we treat bones differently. Each model can have a skeleton made up of bones. Skeletons can be unique for each model, or shared between models. Animation occurs on a skeleton, not a model. When a skeleton is animated, every model that uses that skeleton will display the same m

Leadwerks Game Engine 5 Beta Update

An update is available for beta testers. What's new: GLTF animations now work! New example included. Any models from Sketchfab should work. Added Camera::SetGamma, GetGamma. Gamma is 1.0 by default, use 2.2 for dark scenes. Fixed bug that was creating extra bones. This is why the animation example was running slow in previous versions. Fixed bug where metalness was being read from wrong channel in metal-roughness map. Metal = R, roughness = G. T

How to construct own machines with joints.

Using joints Hinge() Joints are funny and powerful to build machines. They allow to use mass (gravity), different masses on different part of the machine depends on what you need, frictions, and limits. By this machine, the only enabled motor is the first big oval cylinder, which is turning. The rest is articulated with disabled hinge joints.

Texture Atlas & Animation

Hello community, long time no see. I am working on my own graphical user interface, for my super duper rpg game :). The use separate textures for each button state, etc. I consider it not effective! It is better to load the texture with the atlas of the whole GUI once. And use her. In order to draw a texture from the atlas, we need to slightly modify the standard shader (drawimage), and save it under a different name (drawimagerect). Shader #version 400 uniform vec4 drawcolor

Leadwerks Game Engine 5 Beta Update

A new beta update to Leadwerks Game Engine 5 is available now. New stuff: Streaming terrain CopyRect and Texture::SetSubPixels Texture saving Note that the "SharedObject" class has been renamed to "Object" and that math classes (Vec3, Vec4, Plane, Mat3, etc.) no longer derive from anything.

Streaming Terrain in Leadwerks Game Engine 5

The terrain system in Leadwerks Game Engine 4 allows terrains up to 64 square kilometers in size. This is big enough for any game where you walk and most driving games, but is not sufficient for flight simulators or space simulations. For truly massive terrain, we need to be able to dynamically stream data in and out of memory, at multiple resolutions, so we can support terrains bigger than what would otherwise fit in memory all at once. The next update of Leadwerks Game Engine 5 beta suppo

Random generated Forest: About performances.

Hellö Here are a few thoughts about finding the best way to create  a dense forest, with different models, quickly, dense and allowing good performances by walking and driving.   I first try with the vegetation tool. https://www.leadwerks.com/community/profile/15151-marcousik/?status=10763&type=status           I got good results but not by driving and I find that the collision checked causes the lost of 40 FPS (from 60 by to 20) making the game unplayable.

Building Textures in Leadwerks Game Engine 5

The new engine features advanced image and texture manipulation commands that allow a much deeper level of control than the mostly automated pipeline in Leadwerks Game Engine 4. This article is a deep dive into the new image and texture system, showing how to load, modify, and save textures in a variety of file formats and compression modes. Texture creation has been finalized. Here is the command: shared_ptr<Texture> CreateTexture(const TextureType type, const int width, const in

Project Workflows

It's funny how all of the various features in the new engine are interconnected and development just flows from one to another. I was working on terrain, and I needed to save out some texture data so I implemented Pixmaps, and I wanted to add Basis support and DXT decompression, and then I started converting texture formats, and now I need a way to manage this all. This is an idea I have had for several years and I finally got to try it out. Leadwerks Game Engine 4 has a strictly defined wo

Basis Universal Texture Support

Last year Google and Binomial LLC partnered to release the Basic Universal library as open-source. This library is the successor to Crunch. Both these libraries are like OGG compression for textures. They compress data very well into small file sizes, but once loaded the data takes the same space in memory as it normally does. The benefit is that it can reduce the size of your game files. Crunch only supports DXT compression, but the newer Basis library supports modern compression formats like B

Advanced Terrain Building in Leadwerks Game Engine 5

In Leadwerks Game Engine 4, terrain was a static object that could only be modified in the editor. Developers requested access to the terrain API but it was so complex I felt it was not a good idea to expose it. The new terrain system is better thought out and more flexible, but still fairly complicated because you can do so much with it. This article is a deep dive into the inner workings of the new terrain system. Creating Terrain Terrain can be treated as an editable object, which i
