$ begingroup$ But be careful - when you save your user settings, Blender will open from then on exactly how it was in that state. If you changed the window arrangement, messed with the theme colors, or had a half-finished project open, Blender will use that exact setup as your startup file. $ endgroup$ – X-27 is done with the network Mar 27 '18 at 16:50. Blender is an open source and cross-platform 3D designer and animator that provides you with a large number of tools with texturing, lighting, modeling and animation capabilities in a single simple to use and intuitive app bundle.
Blender is a powerful, professional, and free open source 3D graphics tool that can be used to produce everything from single 2D stills, to full 3D movies in broadcast and cinema quality, and even interactive 3D content for stand-alone playback.
The program comes packed with essential features. A comprehensive modeller supports a range of 3D object types, and fast skeleton creation and automatic skinning help you get started; an in-built raytracer complete with halo, lens flares and fog effects delivers top quality rendering; animation tools support full armature deformation with forward/ inverse kinematics, adding automated walkcycles along paths for easy movement planning; and you get top quality diffuse and specular shaders, accurate physics and particle modelling, even collision detection to aid with real-time 3D game creation.
Once you've finished, your project can be exported for viewing as 2D images, videos (AVI or MOV, say), or a host of 3D formats for possible reworking elsewhere: 3D Studio, AC3D, DXF, DirectX, Lightwave, MD2, Motion Capture, TrueSpace, VRML, and more.
And if you'd like to get a feel for what the program can do, then try watching Blender-created movies like Sintel and Big Buck Bunny - the results can be very impressive.
