It's been around for some years now. It's a completely free, open-source 3D program with everything from modeling, simulations, rendering, animation, texturing, sculpting, video editing, motion tracking, almost anything you can think of related to 3D. https://www.blender.org

If you decide to learn it, I highly recommend starting here. Blender has a big learning curve at first but once you get the hang of it, it's amazing!
