“Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation.”
I strongly advice you to download blender if you are interested in to create 3d anims or characters etc. from blender.org.
You can also find educational videos in youtube. I advice Sebastian’s videos on youtube which I gave channels link below to learn charcter creation.
I wish you happy programming and desingning!!
