The handler is pretty generic - I just define where is UP direction and that’s it
If you haven’t seen Falafel’s Scripting Timelapse - Me Speedrunning A RIM Animation / Scripting Timelapse - Dehya by Haruya check it out
The OFS tracker works roughly the same way - you have to define what direction is UP and it tracks a point over it
My version allows R1/R2 as well though
I think it can be simplified so saying “This tracker defines default penis length and rotation” and as much as it can
