oh, I didn’t know that. thank you!
anyway, the problem is that you’re putting pauses in the looping command, but you can only have overlay commands
I’d change it to something like this
&overlay UA INTRO LOADING DOT 01 opacity 1 in 0 then overlay UA INTRO LOADING DOT 01 opacity 1 in 1.35 then overlay UA INTRO LOADING DOT 01 opacity 0 in 0 then overlay UA INTRO LOADING DOT 01 opacity 0 in 0.45 loop INF times
&overlay UA INTRO LOADING DOT 02 opacity 0 in 0.45 then overlay UA INTRO LOADING DOT 02 opacity 1 in 0 then overlay UA INTRO LOADING DOT 02 opacity 1 in 0.9 then overlay UA INTRO LOADING DOT 02 opacity 0 in 0 then overlay UA INTRO LOADING DOT 02 opacity 0 in 0.45 loop INF times
&overlay UA INTRO LOADING DOT 03 opacity 0 in 0.9 then overlay UA INTRO LOADING DOT 03 opacity 1 in 0 then overlay UA INTRO LOADING DOT 03 opacity 1 in 0.45 then overlay UA INTRO LOADING DOT 03 opacity 0 in 0 then overlay UA INTRO LOADING DOT 03 opacity 0 in 0.45 loop INF times
Idk if it actually works, so you have to try it out
