Bright Engine is a Light-Weight C++ Rendering platform aimed towards, Real-time rendering for both Video Games and Cinematic Animations. It is still very early in its life-cycle, but has been designed with scalability in mind allowing for any form of project to be created. From a first person shooter to a Massively multi-player online game.

The mission is to create a robust development tool that acts as a viable alternative to other mainstream products by providing complete control and customisability, allowing the Engine to suit any project while still remaining simple and efficient to use. While the Editor does the heavy lifting, you can go into the heart of your project and edit the source code of the executable to achieve anything you want (including adding your own custom or other 3rd party libraries).

Bright Engine has undergone and still continues to be rigorously tested by a growing community of dedicated game developers who have ensured maximum stability with each new update.

If you are interested in Bright Engine and want to snag up a free copy you are welcome to join the Discord community to ask questions to existing testers, get real time development progress updates or even download the engine to try it out for yourself!

This latest update brought a much needed rework on several systems while also laying the foundation for upcoming systems such as Light Probes, Baking and Day/Night Cycles! Skyboxes are now significantly more optimised, and approximately 2500 lines of duplicate/redundant code was removed from the project. Model LOD was introduced to allow for more optimisation capabilities for the artists along with lots of minor bug fixes.

New Features

Starting with the most anticipated system that came with this update, Model LOD’s are fully supported up to 5 levels of detail. You can complete control over the distances between the camera and the object required before different levels swap out. Smooth blending has also been added as an optional setting which helps remove the ‘popping’ effect that many games suffer from, and instead of a simple fade between stages, you can choose to use a dissolving filter instead to create a less noticeable transition!

One problem we found from our previous experience and looking at other project, is exporting lots of separate LOD files for each object is a time consuming experience and results in a rather messy project folder. We have addressed this issue by allowing Bright Engine to detect the LOD levels of a model from within a single model file, so you only have to export it once and Bright Engine does all the rest!


The other addition made in this update was the skybox rework. Visually the results are identical, however in the backend, the system is drastically more advanced. Memory consumption has been reduced by approximately 10% and loading times have been reduced from around 4 seconds to almost nothing! In the next update, the skybox is going to be getting another upgrade with the introduction of a room system, but we’ll talk about that later.

Changes & Improvements

One thing which we try to ensure is code quality, and going back through some of the older systems when working on Skyboxes, we found some pretty horrific stuff in the rendering code. We successfully removed just under 2500 lines of duplicate code that dragged performance down for literally no reason. We are positive that there is bound to be more redundant code scattered throughout the project and so we will continue to be hunting it down and eliminating it!

We also took a look at zone switching and found some nasty memory leaks that managed to go undetected for quite some time, these have been sealed up. It was actually quite fortunate this happened because it lead to us also discovering a bug where textures for 3D models were being loaded twice! (yes we fixed that too).

Alpha blended objects also finally work once again! This bug has been present for a long time and we thought it was about time we addressed it, so Blending alpha works perfectly and rather efficiently too!

There were some small general tweaks with the UI, making it a more responsive and make it feel less clunky. We also switched from Right Click Select to Left Click Select, upon community request. We do intend to add an options menu in future where you will be able to set your own keyboard and mouse shortcuts to use.


Bug Fixes

  • Fixed bug where creating a new project would cause the engine to create it as an older version.
  • Fixed bug where alpha Blended models didn't have proper transparency
  • Fixed bug where alpha Blended models retained emission data from other models in the zone
  • Fixed bug where alpha Blended models had a metallic twang to their surfaces
  • Fixed bug where removing a cubemap from the Cubemap Manager wouldn't clear the memory from the temporary files, sometimes causing a crash
  • Fixed bug where Emission textures would only appear if Bloom was enabled
  • Fixed bug where switching between zones sometimes caused a crash
  • Fixed bug where switching zones while having an object selected would cause the 3D cursor to still appear in the new zone without anything selected
  • Fixed bug where some data of Terrain and 3D models wasn't being removed from memory when switching zones (fixed memory leak)
  • Fixed bug where some data of the Skybox wasn't being removed from memory when switching zones (fixed memory leak)
  • Fixed bug where adding a new Emitter sometimes gave the error that no emitters exist in the project even though they do
  • Fixed bug where adding a new Cubemap would not be picked up by the Editor until the engine was restarted
  • Fixed bug where calculations for the 3D cursor were being constantly repeated every frame instead of just once (which is all it needs)

What’s Next?

With this performance patch out of the way, we will be working on the last piece of the 0.1.2 patch series. The introduction of Rooms. Rooms will allow you to set the environmental settings of each zone in specified areas. For example if you character enters a swap, you’d want to adjust the fog settings and ambient lighting to help create a damp darkish environment rather than being stuck with a single collection of settings for an entire zone.

i have one question!
can you use it for game maker studio 2?

i mean like particles?

I'm afraid not, the particle system has been created to work exclusively with Bright Engine. I'm not entirely familiar with Game Maker Studio 2 but I do believe that they have their own Particle System

Hello, I thought I would post about Bright Engine. This engine, so far looks very promising. Bright Engine has a really well done animation manager.. Not even the big engines out there can compare to what Bright Engine has, especially the particle editor. which Is very easy to use as well. This engine has a cube manager which is extensive as well as an Engine diagnostics mode with GPU information.

All in all the Bright Engine looks great and works very well, I can’t wait to see more being developed.
