Unreal Engine 4 vs Blender

Blueprints are authoring tools designed for non programmers so designers and other team members can help tweak and prototype. UE4's Blueprint scripts resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish and games a lot faster to prototype.

Epic provides multiple official video tutorials, lots of free example projects and content, an extensive wiki and regular streams showing how to use latest features.

Allows a texture/material artist or VFX artist to create amazing effects from the ground up.

The engine, including full access to source code, is free to use; a 5% royalty is due only when you monetize your game or other interactive off-the-shelf product and your gross revenues from that product exceed $1,000,000 USD.

UE4 gives full access to the C++ source code allowing editing and upgrading anything in the system.

Voxel cone tracing is a similar algorithm to ray tracing, but uses thick rays instead of pixel thin rays to be able vastly decrease the amount of computational power needed.

Unreal Engine 4 is one of the best game engines. It is super easy. It dosent require any use of coding due to Animation Blueprints

This engine exports for a big range of platforms including Linux. The editor can be run on Windows, MacOS, and Linux (Early Access).

Forums have many active and friendly members that are quick to respond and help out. Even staff is very active on forums.

This is ready to make the next AAA game.

Recompiling an entire game to test a small change takes up a lot of time. UE4 quickly compiles in seconds instead of minutes improving iteration time by an order of magnitude.

New feature releases can be commonly expected about once a month.

Almost everything a game developer wants has a deep and sophisticated tool waiting for them in UE4. No external plugins are needed to make powerful materials, FX, terrain, cinematics, gameplay logic, AI, animation graphs, post process effects, lighting etc.

Blender is licensed under the GPL. Some Blender modules such as the Cycles rendering engine are licensed under the Apache 2.0 license.

Support lots of modern 3D formats including DAE and FBX - ideal for game developers.

Blender runs the Cycles path tracing engine under the hood. Cycles is a very powerful rendering engine capable of full path tracing (light fall off, caustics, volumetrics). It is mostly compatible with OpenCL and CUDA rendering, and is implementing mycropolygon displacement features. The upcoming release has a viewport engine called EEVEE whereby you can see and interact with your work in render mode in real time!

Blender embeds Python 3, which can be used to write add-ons, tools, extend the interface, rig characters and automate tasks.

Blender provides a full rigging system, and automates animation by interpolating between keyframe positions.

Releases are made every ~3 months.

Although Blender's 3d painting and sculpting tools (mostly painting) are not at par with specialized software like Substance Painter, ZBrush, or Mari, it is more than capable of getting most jobs done if the user takes the time to learn and understand it.

Blender's node-based compositor has comprehensive video sequencing and post-processing features.

Good keyboard shortcuts for everything. Keep your left hand on the keyboard and your right hand on the mouse.

It offers a round solution (it covers many areas and professional fields) for a freelancer, for free, constantly updated, very polished, and allowing high quality results that clients do require. After some learning, it becomes very useful for professional work.

There's a huge community to help you get started immediately.

The trick with Blender is to get used to its usage philosophy, as it keeps consistent through all the application. Once you get it, every feature or addition is learnt naturally, almost effortlessly.

You don't have to switch between software when you want to do different things. Because modeling, sculpting, composting, video editing etc can all be done in blender.
