Blender is a fantastically powerful 3D modeling tool, which is extensively used within the games industry. It has recently been updated (2.8) which has brought it in line with industry standard tools, supporting the full pipeline of developing 3D assets for games: modeling, rigging, animation, simulation, rendering, compositing and motion tracking.
Blender (as with all 3D tools) can be very overwhelming when you first start, so we recommend you work through some tutorials before you dive in.
- There is a really great getting up to speed tutorial and general Blender by making a donut with Blender Guru. It is not aimed with videogames in mind, but gives you a good general overview of the tool.
- There are some fantastic Blender tutorials over at CG Cookie, but you need to pay a subscription fee to access.
