Blender 3D is an open-source 3D creation suite used for modeling, sculpting, animation, rendering, and simulation. It supports a wide range of applications, from 3D character modeling to game design and animated films. Blender's robust set of features includes sculpting tools, a node-based material editor, a built-in game engine, and powerful rendering capabilities like Cycles and Eevee. Its open-source nature has fostered a large community of developers and artists who continually contribute to the software. Blender is increasingly used in both professional and indie 3D animation studios due to its versatility, powerful features, and zero cost.
