What is Unreal Engine 4
The Unreal Engine 4 is a game engine created by Epic Games, the creators of the video games Gears of War and Fortnite. The UE4 is available for purchase from Epic Games or other 3rd-party providers. Unreal Engine 4 has seen extensive use in AAA videogames and web applications, such as “League of Legends” and “Guild Wars 2”. The first notable title using UE4 was “Dota 2”, released in 2013.
Since its release, the Unreal Engine 4 has been used to create a wide range of games, such as: “Astroneer”, “Apex Legends”, “Fortnite Battle Royale”, “Hellblade: Senua’s Sacrifice”, “Hyper Light Drifter”, “Moonlighter”, and many more. Due to the wide range of games available using UE4 that are also cross-platform, users can now play them on a variety of different devices, like mobile phones and consoles.
Unreal Engine 4’s availability for purchase by 3rd parties allows smaller developers to create games without needing to worry about low-level development.

What is Blender
Blender is an open-source 3D graphics engine that can be used to create video games, movies, visual effects and other multimedia content. Its source code is available under the GNU General Public License. Blender is free software available for the Windows, macOS, and Linux operating systems with plug-ins for many other 3D software packages. Blender’s features include advanced simulation tools such as rigid body dynamics, soft body dynamics and fluid dynamics, modifiers, weight painting and a built-in Python API.
Blender is available for Windows, macOS, and Linux, with version 3.4 released in December 2016. New versions of Blender based on the Cycles renderer are mostly released roughly monthly. The foundation of Blender’s rendering pipeline is a multisample anti-aliasing technique called Temporal Anti-aliasing (TAA). Blender’s rendering pipeline also uses subsurface scattering to generate realistic lighting, and Blender has very advanced particle-based smoke and fire.
Blender is a commercial product, with a fully featured licensing option for businesses and universities, though those using Blender solely for noncommercial projects are not required to pay. It has been used in numerous AAA games including Assassins Creed: Syndicate (2015), Far Cry Primal (2016), GTA V (2013), The Division (2016) and Watch Dogs 2 (2016).
Blender Cycles, Blender’s primary rendering engine, is powered by the industry-standard Open Shading Language and supports features like volume rendering, raytracing, caustics and ambient occlusion.

How Unreal Engine 4 is better than blender
Blender is better for some people because it is free and open source.It is also open to modification. Unreal is more expensive, closed source and not as customizable.
There are many different types of engines in the world, some more powerful than others. Unreal is one of these types of powerful engines. However, blender has a much less powerful engine and therefore cannot create games with good graphics or renderings.
Unfortunately for blender, it only has a little over 80,000 lines of code. This is much less than other engines. For example, unreal has about 3.5 million lines of code, a difference of 2.6 million. Unreal can do so many more things than Blender because it has more lines of code for developers to use and therefore customize it to their needs and wants.

How blender is better than unreal engine 4
Unreal Engine 4 is better because it is integrated in the game engine.It has a more powerful simulation with physics, animates objects and has advanced shading.Blender has simple and not too complex animation and lacks advanced shading, which gives it a bad impression in some areas.Blender also doesn’t have physics simulation and advanced shading.
Unreal Engine has pixel-based lighting while blender uses radiosity,global illumination,light maps and shadow maps.Unreal engine 4 uses a deferred rendering technique,whereas blender uses a classic forward renderer.Also Unreal Engine supports volume triangle meshes,which is the best way to make fluid simulations in 3D modeling software. While blender does not support this feature yet it would take ages to achieve it with blender because of its complex interface and hidden commands.
