r/VRchat on Reddit: Unity VRChat SDK - Avatars error
February 13, 2024 -

I’ve been struggling with this error that I have no clue how to fix that will not let me upload ot test my Vrchat avatar. It says “Object reference not set to an instance of an object” and the error message mentions a script under the VRChat SDK - Avatars package called “VRC Sdk Control Panel Avatar Builder”, so I’m guessing this is probably the culprit in some way but i’m not entirely sure and I wouldn’t know how to fix it either way since this is the first avatar I’m trying to upload. This error wasn’t a issue a few days ago but since then i’ve added poiyomi shader and used it for some emissions and I also added some props. If anyone has any clue on what could be wrong I would greatly appreciate some help! (also might be worth mentioning that the validations menu is completely blank as shown in picture)

Your sdk is missing a script and it can’t refer back to your avatar. If it was because of your avatar it wouldn’t be referencing the SDK ...

July 31, 2024 - In short double check your project, if it has missing stuff that came with the model you deleted (like colliders or bones that mattered) or if it has missing vrchat necessary scripts, you will often get this error.
