If you want to use scripts in VR I did a short guide a while ago:
If you want to use scripts on your PC you can use one of the following:
- https://funscript.io/play
- https://discuss.eroscripts.com/t/handycontrol-1-2-0-24-05-2021-sensor-integration-control-handy-nobra-with-movements/94
- https://discuss.eroscripts.com/t/scriptplayer-1-1-0-new-release-18-01-2020/206
In all cases you have to drag the video/script into the player. You can find more details in the links, but if you will have questions just ask.
