i figured out how to add them to the avatar, just drag the prefab you want onto the body or the armature or wherever you feel like it if you know what your doing, i got it on the avatar and the only issue i had after was figuring out how to create a gesture to turn it on and off, im still lost on that kinda thing. im currently in the process of watching a few more videos and i know how to create the gesture for the custom emote but i have no idea how to make the particle work with said gesture, and i cannot for the life of me find anything on how to do this.
@Necta, this is common problem sometimes, you need to create an entirely new unity project, import the sdk and the shaders and anything else essential to the avatars your using and just start fresh, its the sdk deleting itself or becoming corrupted for whatever reason. it happens to me all the time, reimporting the sdk does not work, i have tried so many fixes. the only thing that has worked every single time was creating a new project. it might have something to do with conflicting packages even. either way try making a new project and starting fresh.
how do you add the morphs for the things you didnt add, i tried google but it wasnt any help figuring it out. is there a tutorial you can point me toward? any help is appreciated im still getting the hang of avatar creation, but so far only managed to upload stock avatars with no gestures, physics or anything else added so this is actually helping me learn as well.
