# vfx-extends-invalid

> Talos next · Since next

A `*.vfx.json` that `extends` a parent is wrong: an unknown preset, a parent file not there, a loop or more than 4 levels, a key that belongs in `set`, a param the parent does not have, a `set` or `unset` pointer to something the parent does not hold, or a pointer that is not one.
