Now, let’s dive into the details!

Application Logic (Scripting)

Unity and Unreal Engine have their unique approaches to application logic scripting, catering to different preferences and skill levels.

  • Text-based scripting

In Unity, C# is the primary scripting language. It is known for its friendliness and faster learning curve compared to C++.

C# is well-suited for common use and software architecture implementation at scale, making it easier to maintain as the application grows. Unity allows developers to create an entire project using only C#.

On the other hand, Unreal Engine utilizes C++ for scripting, complementing it with the Blueprint tool. While C++ is powerful and allows for in-depth software architecture, it is more challenging to learn and use than C#.

Unreal’s implementation of C++ relies heavily on Unreal-specific code that doesn’t directly translate to general C++ usage. Creating an entire project in Unreal using only C++ is impractical, as Blueprint is a significant part of Unreal’s visual scripting approach.

  • Visual scripting

For those who prefer a visual approach to programming, both engines offer solutions, each with its characteristics.

Unity provides a visual scripting package known as Bolt. It is a node-based logic engine, that allows designers or developers to implement behaviors for game objects directly in the editor.

While Unity’s scripting documentation is C# centric, learning C# scripting makes it easier to grasp visual scripting. Extending visual scripting nodes in Unity requires no special skills.

Unreal, on the other hand, uses Blueprint as its primary visual scripting tool. It is especially favored by beginners, with C++ available for tasks not achievable through Blueprint.

UE’s scripting documentation is Blueprint-centric. Learning Blueprint doesn’t directly translate to C++ scripting, requiring additional training. Extending Blueprint nodes in Unreal requires knowledge of C++ libraries and engine-specific macros.

Both shine in real-time rendering for XR experiences, but they have distinct approaches. Unreal delivers impressive graphics automatically, while Unity needs some tweaking to match that level.

If you’re targeting mobile in Unreal, you might have to scale down the graphics, and the opposite is true for Unity. In XR, optimization often takes precedence over flashy graphics, making Unity’s default setup more suitable.

Unity’s rendering system is flexible with Shader Graph and HLSL code, giving experienced developers more control. Yet, Unity struggles with transitioning between different render pipelines, which can be time-consuming.

Unreal lacks direct HLSL integration but offers a user-friendly node-based editor. However, Unreal shaders often need external source code. Unreal provides a wider range of post-processing choices compared to Unity’s basic options.

Real-time Cinematic Rendering

Both Unity and Unreal Engine are getting good at creating realistic scenes in real time, but they’re finding their best uses in different areas.

Unreal has been a leader in things like architecture and movie effects, while Unity’s High Definition Render Pipeline (HDRP) is showing its strength in high-quality visuals.

Unity showcased a real-time cinematic trailer called ‘Enemies’ at GDC 2022.

This trailer had a detailed female model with realistic features like moving eyes, facial expressions, and lifelike hair. The level of detail was so impressive that it was hard to tell if it was real or not.

This highlights Unity’s growing ability to create stunning visuals in real time, especially in areas like advanced car visualization. While Unreal is still strong in various fields, Unity’s HDRP is proving itself as a powerful tool for delivering lifelike and beautiful visuals in real-time cinematic experiences, particularly in XR development.


Unity and Unreal Engine offer different tools for creating special effects in XR development. They commonly use animated planes with custom materials for visual effects (VFX). These planes align with the camera, and shaders handle the animation. However, this method lacks reactive procedural effects.

Unity’s VFX Graph is a user-friendly tool with nodes for creating and manipulating particles. It’s like Unity’s Shader Graph but has limitations on certain platforms, especially in the Universal Render Pipeline used for mobile devices.

Unreal’s Niagara is also user-friendly but may feel different for Unreal developers. It’s modular, allowing for interactive effects, but learning it might be a bit unfamiliar.

On mobile, Niagara has limitations, not supporting some rendering features and needing specific settings for Android and iOS.

Target Platforms

Both Unity and Unreal Engine let you create apps and games for various devices like Windows, Mac, Android, iOS, and gaming consoles. In XR (Extended Reality) development, Unity has an extra advantage because it supports publishing HTML5 for the web.

Unreal used to support this but stopped after version 4.24. So, if you want to make XR experiences for the web, Unity is still a good choice.

For XR development, Unity tends to work better for virtual and augmented reality. Unity gets toolkits for these technologies faster than Unreal.

Unreal may take longer to release these toolkits, and some features supported by Blueprints (a visual scripting system) might be limited compared to Unity.

In simple terms, both are good for making things on different devices, but if you’re into XR and want to reach the web, Unity has a bit of an edge.

Creator-focused Multiplayer XR Experiences

Unity is a popular choice for making multiplayer XR experiences like Zenith MMO and VR Chat, while Unreal Engine faces challenges in this area.

One big reason is Unity’s support for runtime mesh access, allowing easy customization of environments and avatars. Unreal, until recently, had limited features for this, making it tougher for creators.

Unity is friendlier for creators with its Asset Packs, letting them easily add different art assets to their games. Unreal has DLC and patching features, but they’re not as user-friendly.

Although Unreal has made progress in runtime loading with formats like GLTF, there are still optimization challenges, especially when constructing skeletal meshes, causing potential rendering issues.
