When comparing Ren'Py vs Blender, the Slant community recommends Blender for most people. In the question“What are the best 100% free and easy game engines for beginners?” Blender is ranked 10th while Ren'Py is ranked 26th. The most important reason people chose Blender is:
Blender is licensed under the GPL.
Ranked in these QuestionsQuestion Ranking
Available on Windows, Linux, OSX, iOS and Android.
Pro Active and friendly community
Pro Reasonably good at creating puzzle and point-and-click games
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 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. The upcoming release has a viewport engine called EEVEE whereby you can see and interact with your work in render mode in real time!
Pro Supports both low-poly and hi-poly modeling
Pro Includes video editing & compositing tools
Blender's node-based compositor has comprehensive video sequencing and post-processing features.
Pro Regular release schedule
Releases are made every ~3 months.
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 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 Has a large community
There's a huge community to help you get started immediately.
Con Not for every genre
While technically capable of creating 2D games in any genre, Ren'Py excels in creating visual novels and has a reasonable feature set for creating puzzle and point-and-click games. Other genres are best tackled by other engines.
Con Outdated Documentation and official built-in tutorials
Unfortunately, you will have to hunt relevant info on how Ren'py script works. The Ren'Py dev has the working tutorials on his Patreon, other than that you might as well just code in Python.
Con Requires knowledge of Python to use
Con Difficult 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 Too many possibilities, no unified workflow
The operations are not optimized enough for specific 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.
