Is Unity still a viable option for game development?

Whether you're a seasoned expert or transitioning from 2D to 3D environments, understanding the potential of Unity's tools and features is crucial for your growth. Discover the world of advanced Unity development through insightful comparisons and an overview of the latest Unity beta.

## **Unity vs. Unreal: The Changing Landscape**

Choosing between Unity and Unreal used to be a straightforward decision based on individual skill sets. Developers with a coding background gravitated towards Unity due to its compatibility with C#, a robust yet understandable programming language. In contrast, Unreal appealed to artists due to its visual scripting solution, enabling the creation of games without any coding. 

With Unity introducing native visual scripting and Unreal enhancing its C++ capabilities, it's now possible to build games regardless of programming experience. Creating shaders has become much easier with Unity's Shader graph, which eliminates the need for HLSL programming knowledge.

Both Unity and Unreal now offer a vast range of free assets and tools, making game development more accessible than ever before. In comparison, Unreal visual scripting blueprint system is powerful and beginner-friendly. Unity counters with an active community, comprehensive documentation, and many online tutorials.

The belief that Unreal offers superior graphics compared to Unity may hold true for AAA games but doesn't necessarily apply to indie games. In fact, overusing Unreal's advanced features could potentially lead your indie game into AAA game territory.

## **Unity 2023.1.0b19 Beta: What's New?**

The latest beta version of Unity introduces several enhancements, including:

1. Improved features for High Definition Render Pipeline (HDRP) and Universal Render Pipeline (URP), such as Temporal Anti-Aliasing (TAA) and FXAA Quality Improvements.

2. HDRP now supports High Dynamic Range (HDR) display output and offers improved water system functionality.

3. The Ray Tracing API and HDRP's ray-traced effects, including shadows, reflections, and global illumination, are officially out of preview.

4. Light and Decal Layers are now unified in HDRP and URP.

5. Adaptive Probe Volumes, now out of preview, offer improved core functionality and user experience.

6. The 2023.1 update includes graphic improvements and additional connectivity types for multiplayer solutions.

7. A new transport layer improves scalability and performance in multiplayer networking.

8. Updated support for .NET 6.0 LTS and .NET 7.0 has been introduced.

9. Unity's Editor UI toolkit has been improved, offering more extendable areas and enhanced interaction with the Unity Editor.

10. The Entities Package is now incompatible with the 2023.1 beta; upgrading to the 0.19 package is recommended.

## **Unity vs. Unreal: The Race for Innovation**

Unity and Unreal continue to innovate and introduce enhancements. Unity's Entity Component System promises to enhance game performance significantly. On the other hand, Unreal has released Nanite to support high poly count models, and Lumen, a real-time lighting solution. Unity's Visual Effect Graph now simulates millions of particles on the GPU.

Despite the ongoing online debates about which engine has superior technical capabilities, both Unity and Unreal are competent and capable tools. Each has its strengths, and numerous beautiful games have been created on both platforms.

So, the choice of the engine should not be dictated by the prevailing sentiment or the notion of one being better than the other. Instead of following a set standard, you should base your decisions on what makes you comfortable, what you are skilled at, and what you hope to achieve.

## **The Challenge of Scaling 3D Games on Unity**

While Unity is recognized for its proficiency in 2D game development, transitioning into the 3D realm can introduce complexities. Unity enables you to create stunning concept scenes easily but expands these into larger projects, especially on lower-performance platforms like Nintendo.

Switching between scenes can be challenging in Unity 3D game development. These challenges include problems with real-time lighting performance and the creation of Levels of Detail (LODs), which add complexity to the process.

## **The Current State of Unity**
 

At first glance, Unity's attempts to compete with Unreal's innovations may seem limited. The 'Auto LOD' project on GitHub has stopped, and the global illumination tool 'Enlighten' is being phased out, indicating significant changes in the works. However, Unity's history of evolving to meet the changing needs of the developer community indicates a continual strive for improvement.

## **Conclusion: Unity or Unreal**

When it comes to game development, choosing between Unity and Unreal is a crucial decision that often depends on personal preferences and project goals. Each engine offers unique features: Unreal's Lumen and Nanite may entice some, but these features might not be essential for smaller-scale projects or games targeting lower-performance platforms.

On the other hand, Unity still holds a significant position in the game development sector due to its large user base and strong market presence. Unity's market share currently stands at 28.01%, overshadowing Unreal Engine's share of 14.82%. The Unity 3D subreddit has 337k members, while the Unreal Engine subreddit has 222k members in their respective online communities.

Looking at the projected growth of the game engine market, which is estimated to surpass USD 5 billion by 2032, it appears that Unity is in a strong position. Given its extensive user base and market share, its proactive approach to introducing comparable technologies only strengthens this position.

However, the decision ultimately comes down to you, the developer. Unity and Unreal offer many opportunities to craft unique, compelling gaming experiences as they continue to innovate. Regardless of your choice, the game development industry is exciting and filled with endless possibilities for creativity and innovation.
