When comparing Blender vs uScript + Unity3D, the Slant community recommends Blender for most people. In the question“What are the best game engines for beginners and non-programmers?” Blender is ranked 9th while uScript + Unity3D is ranked 22nd. The most important reason people chose Blender is:
Blender is licensed under the GPL.
Ranked in these QuestionsQuestion Ranking
Pro Free and open source
Blender is licensed under the GPL.
Pro Python extensibility
Blender embeds Python 3, which can be used to write add-ons, tools, extend the interface, rig characters and automate tasks.
Pro Powerful animation suite
Blender provides a full rigging system, and automates animation by interpolating between keyframe positions.
Pro Wide import and export format support
Support lots of modern 3D formats including DAE and FBX - ideal for game developers.
Pro Supports both low-poly and hi-poly modeling
Pro Regular release schedule
Releases are made every ~3 months.
Pro Has a good rendering engine
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.
Pro Keyboard shortcuts
Good keyboard shortcuts for everything. Keep your left hand on the keyboard and your right hand on the mouse.
Pro It has sculpting and 3D painting features
Although blenders 3d painting and sculpting tools (mostly painting) are not at par with specialized software like Substance painter, z brush, or mari; it is more than capable of getting most jobs done if the user takes the time to learn and understand it.
Pro Includes video editing & compositing tools
Blender's node-based compositor has comprehensive video sequencing and post-processing features.
Pro Node based modeling support
Pro Very useful for a freelancer
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.
Pro Coherent and streamlined workflow / internal use logic
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.
Pro Automatically generates nodes for third-party script assets
uScript's nodes are a visual representation of actual code blocks, and it takes advantage of C#'s reflection capabilities to automatically create nodes for any scripts it finds in your project, regardless of the source. This makes it inherently compatible with pretty much everything.
Custom nodes can also be created by hand, for cases where the automatically created ones contain more elements than they actually need.
Pro Versatile flow diagram script model
Modeled after UDK's Kismet (the predecessor to UE4's Blueprint), uScript's 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.
Pro Generates C# source code
Nodes are translated directly to C# files in your project. This is great for learning to code, and also for advanced users who can use uScript for fast prototyping and then further optimize the scripts if necessary.
Con Steep learning curve
Blender is not a very intuitive 3D modeling software. It has its own ways of doing things, and it is often hard to guess how to achieve simple tasks.
Con Poor particle system
The Blender particle system can at times be a little limiting and finicky (and buggy) to get working. Even if it can get most straight forward jobs done, it is far from the most advanced system, and could benefit largely from advancements.
Con Not that easy to use
It's a lot more complicated compared to something like Playmaker. Same tasks take a lot more time.
