Impostors
What are Impostors?
Impostors are avatar body doubles, allowing you to see avatars in situations where you would typically see a fallback avatar or robot. They are intended to bridge gaps between different systems/user types in VRChat. For example, if a user’s avatar was only uploaded for Windows, VRChat makes an acceptable impostor for Quest automatically. You can only generate impostors for avatars you own and have uploaded.
Even if you've never uploaded a cross-platform version of your avatar, or if your avatar is "performance blocked" due to its performance rank, other users will still be able to see an impostor of your avatar. Eventually, impostors will be auto-generated, but for now, you create them with a few easy steps. Once you've made an impostor, you can toggle it on and off - when it's off, your fallback avatar will be shown instead.
How do I create an Impostor?
The first step to creating an impostor is to create and upload an avatar.
Once you've uploaded an avatar, creating an impostor for it is easy:
-
Log in to the VRChat website.
-
Navigate to the info page for the avatar you'd like to impostorize. You can do this by pressing "Avatars", then "My Avatars", then the name and icon of the one you want.
-
Click "Generate Impostors", or, if the avatar already has an impostor that you'd like to be updated, "Regenerate Impostors"
-
Wait.
-
Refresh the page, after some time you should now see that your avatar has impostors for Quest and PC.
Previewing an Impostor
Once you've got your impostor generated, you're probably going to be pretty excited to see how it looks! Well, no worries, we've got you covered!
Once you've logged into VRChat, open the Avatar menu, and click the avatar that you generated an impostor for.
You should notice that the "Features" of the avatar now includes "Impostor".
You should also see a new button underneath the avatar model preview, which will allow you to switch between viewing the impostor and the normal avatar for a quick preview.
Impostors that are previewed in the menu may exhibit more artifacts than they would when viewed on another player.
VRCImpostorSettings
Impostors come out pretty good by default. However, complex avatars may benefit from some customization.
To customize your impostor, add the "VRCImpostorSettings" component to your avatar before uploading it. Changing the settings of this component allows you to change the impostor's appearance. You can add multiple "VRCImpostorSettings" to customize different body parts.
