Blender has a complete VFX pipeline in one single software package. Blender has tools for modeling, sculpting, rigging, animation, rotoscoping, chroma keying (green screen), motion tracking, smoke, fire, and fluid simulation, particles, destruction, physics, color grading, node compositing, and video editing.
Blender has the most artist friendly and versatile UI of all 3D software; easy to modify for your specific needs. Blender also has the fastest workflow in the industry.
