When comparing Blender vs Substance Painter, the Slant community recommends Blender for most people. In the question“What are the best 3D texture painting softwares?” Blender is ranked 1st while Substance Painter is ranked 2nd. 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 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 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 Node based modeling support
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 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 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 Allows you to paint in full 3D
Since Substance Painter allows users to paint in full 3D, it can be used not only to paint full textures, but can also paint masks which can then be used in other tools (like Substance Designer) for material filter generators (like the ones used to make edge wear and dirt)
Pro Painting and procedural editing of textures
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 Expensive and impossible to run without an expensive graphics card
The free trial is the only thing free. You'll have to pay a lot of money for the full version, and even if you do get it, you will have to pay for an expensive graphics card to use it, which means a lot more money flying out of your wallet and/or bank account.
Con Cannot export in a procedural format
You can not export substance (sbsar) files in Painter.
