How to animate in Blender on 2s When doing animation in blender, how can you get the illusion that it was animated on 2s. I do my animation 24 FPS.

A perfect example would Spider-man into the spider verse. The entire movie is on 2s.
You can perform your animation using odd numbers only, then select all objects or armature you used and go to the menu: Object (or pose), animation, bake action. Set the frame step to 2, then select all the new action and set the interpolation to "constant".
