Frequently asked questions

Do FOS Essentials packs work on Quest?

Yes. Every pack is written for cross-platform worlds: no heavy post-processing, controlled draw calls and respected network budgets. Quest is treated as the constraint that decides the defaults, not as an afterthought.

Do I need to know Udon or C# to use them?

No. Each pack ships prefabs that are already wired. You drop one into your scene and fill in the fields the documentation lists, usually a target transform, a canvas or a list of destinations.

Which Unity and VRChat SDK versions are required?

Unity 2022.3.22f1 and VRChat SDK Worlds 3.10.4 or later, with the Built-in render pipeline in linear color space. The packs target projects managed by the VRChat Creator Companion.

Is FOS Essentials Core free, and do I always need it?

The Core is free and required by every pack. It provides the shared base behaviour, the logging convention, the player registry and the Hub, which lists what is installed and what each pack needs.

Can I install a single pack without the others?

Yes, apart from the Core, which every pack needs. A few packs depend on others: Tablet System needs Localization and Teleport. The compatibility page lists every dependency.

What happens to my scene when I update a pack?

Read the pack changelog first. A prefab you modified does not carry your changes over on its own, and a major version number means something you built has to be redone. The Hub refuses a combination whose Core is too old rather than failing later in game.

In which languages is the Unity editor interface available?

English, French, Spanish and German. Inspectors, tooltips and menus all follow the language chosen in the Hub, which is stored per machine rather than per project.
