Ultra Engine 0.9.9 Adds a Built-in Code Editor, Mesh Reduction Tools, and Thousands of Free Game Assets


Ultra Engine 0.9.9 is here with new features, improved usability, and access to thousands of free 3D assets to use in your games. This new update is the most stable and user-friendly version of our engine and editor to date.

Revised Interface

We've made great improvements to the user interface and workflow, based on conversations with the community and usability testing. Mouse tools have been moved into a left-side column for convenience and greater ease of use. A slick new color scheme gives the whole UI a distinctive feel. The new icon set really pops, but it's also functional, making it easier to identify buttons so you can work more quickly.

Built-in Code Editor

Due to popular demand, we've brought back the integrated code editor, with a slick new interface that looks great and provides a clutter-free coding environment. A new Lua debugger provides insight into your game code, without a lot of visual distractions. The new IDE was made possible with the release of @klepto2's Scintilla implementation.

Downloads Manager

The integrated downloads manager provides access to thousands of high-quality assets, including game-ready PBR materials, 3D models, and skyboxes. This system is built on the powerful Invision Community software we use on our website.

Mesh Reduction Tool

The model editor interface has a new mesh reduction tool that lets you easily decimate detailed meshes, to make them ready for real-time use, or to add LODs to a model.

Water Shader

A new water shader and material has been added for more beautiful scenes, with realistic reflection and refraction.

Hi! is it possible to code in C# ? I was reading in some post of 2021 (

) that C++/C# and Lua were going to be the main languages. Is C# in the roadmap or will never see the light of day? thanks

I think we need to make Leadwerks 5 a success before adding C# programming support. What is your background? Are you coming from Unity?

Hi! thank you for your fast reply. Yes I have been working in Unity for sometime and I love C# - I tested Unigine, Stride and Godot. 
Stride is nice however requires a bit too much work and while I'm quite comfortable with C# I never worked with an engine at the core.
Godot is just not for me :) 
Unigine is quite nice but still feels... not 100% it

however I came across your engine by chance and I have been reading your journey here and you are a legend! (<--apologies for labelling you).
I might just support the project at una tantum (buy the engine) because I love few things in general: passionate people, open source and cool projects.

I can say that C# integration would be cool!

BTW bought the engine via Steam just now and decide to start learning Lua. I was looking at beginner's guides..... gave me the final push :) excited to be on board
