You’ll need to have the overlay in front of your character since there is no guitar prop (which is such a shame) and animate the guitar overlay to move in accordance with the animation you use whether it’s side-to-side or up-and-down and add a loop command to it, whether it’s infinite or numbered.
If the overlay needs to be rotated and/or mirrored to fit the animation, you will need to rotate it and/or adjust the scaling with a minus value OR you can edit it and rotate it/mirror it in an editing program before uploading it to the portal, that way you won’t need to rotate it/mirror it in the actual script.
I don’t know if you’re familiar with animating overlays at all or not, but let me know if you aren’t.
Yes, it would. That’s is the only method I’ve seen used in stories for guitar playing with custom guitars/basses. You could create arm overlays and attempt to animate them but it’s a lot of work.
HOWEVER, even though there isn’t any actual prop we can add to characters or remove that are guitars/basses, there’s two that are automatically added to a character if you use any of the guitar/bass animations other than the air guitar animations. Air guitar animations are self-explanatory, basically just meant for pretending to play.
If you don’t like either of those automatic props, then you will need to need use an overlay of your choice and manually animate it in front of your character.
