I'm planning an animation in Blender to be released on my birthday.
One of the scenes features something coming out of... let's call it 'a gap in reality.' It's a humanoid shape, and it's curved.
But I wonder... Is there any way to make a "portal" object that can show an entirely different texture on the inside, or even something semi-dynamic as this Minecraft redstone hax here: https://youtu.be/xewQL6CkMWI
Is it possible for an object to create the illusion of another dimension when looked into, but if viewed from the side, seem perfectly normal?
Thanks, Nefer. (Best answer gets to be put in the credits!)
