Blender

Blender is free online 3D modeling, animating, and video editing software. The first version of Blender was created on January 2, 1994. Since then, Blender has been constantly updated and improved. the current version of Blender is 4.3.2 (this number will be updated in the future)

Right now would be the best time to start learning. there are over 5,000 communities that specialize in Blender. there is so much documentation on this software and people are constantly finding new things to accomplish with it

How To Fix Bugs

blender is not a perfect software so save regularly. The only way to fix bugs is to restart Blender. if you think you found a bug look it up first. it may be a basic setting such as if you're unable to rotate an object check your transform setting: Sidebar (N Panel) > Tool > Options > Transform Under "Affect Only", uncheck Origins. The shortcut is Ctrl-Period
