Question 15 fps Character animation in 30 or 60 fps game

Hi everyone
Im new here, and would like to ask about making characters' animation in 15 fps, while the game itself in 30 or 60 fps. The rotation, scaling and transformation of all objects and characters are still in game's fps.
I want to make the characters animation looks like stop motion or 2D animation.

Thank you in advance, and sorry for my english

 

manually update the animator.

https://docs.unity3d.com/ScriptReference/Animator.Update.html

haven't done it, but if I'm not mistaken calculate the fps = 1/deltaT. then calculate rate = current fps / target fps(15). then multiply deltaT by rate. so animator.Update(deltaT*rate).

 

Thanks for the answer. Ill try that
