Timeline Constant Interpolation Not Working?
DAZ Studio Timeline question:
Let's say my character has their arms crossed from frame 0 to frame 2, and only on frame 3 they're supposed to turn their head to the left. Even with interpolation set to Constant, the head still starts turning on frame 1 instead of staying completely still until frame 3.
I already know the workaround of copying the frame 0 pose to frame 2 so it snaps on frame 3, but I'm looking for the proper fix. Is this just a DAZ limitation or am I missing a setting?

This is the only way, otherwise it will simulate from one pose to another. If you want to delay that movement, you need to copy and paste the key to the frame you want movement to start. Same with all software, unless you physically give it a command, it will simulate by itself.
No, you don't need to copy frames ~ setting interpolation to Constant will do but you need to firstly frame-select (or Ctrl + Select...) keyframe 0 and 3 on the Head node... before changing Interpolation Type to Constant.
Edit: When you see two C marks on keyframe 0 and 3 on Head's rotation node, that means you correctly set them up ~ See the screenshot down below.
