Why use Blender
Blender is a open source 3D development software which does so much more than just modelling. It also allows physics simulation, animation, VFX and more. The community is thriving and some even write custom add-ons to help with specific applications.
Blender is the best option for indie developers who are looking to make 3D games. It may be daunting at first but there are a lot of great free beginner tutorials which can get anyone up and running in no time.
