The combination of target bones and bone constraint angles can affect the performance of MOHO.

I don't know if anyone else is having this problem. The combination of target bones and bone constraint angles can cause MOHO to slow down significantly, to the point where characters on the timeline become impossible to animate (the timeline is either unsmooth or very slow). To fix this, I had to change the bone constraint angle parameters or disable them entirely when using it with target bones (such as legs).

I don't know if it's a problem with the latest version, because I haven't had that problem before. It has happened to me on both PC and Mac.

Hi. Could you share a file so we can test it?
Thanks

I haven't saved any sample files. But I saw a forum thread called "Everything is lagging," and the user called JAWAD shared a link to some characters.

I tried one (shila New), and the same thing happens when animating the character legs and feet targets. The timeline gets stuck. By removing the bone constraints angles of the legs bones the timeline becomes smoother. You can see if the same thing happens to you with that character.
