# Objective
- `bevy_render_macros` fails to build on its own:
```
error[E0432]: unresolved import `syn::Pat`
--> crates/bevy_render/macros/src/specializer.rs:13:69
|
13 | DeriveInput, Expr, Field, Ident, Index, Member, Meta, MetaList, Pat, Path, Token, Type,
| ^^^
| |
| no `Pat` in the root
| help: a similar name exists in the module: `Path`
|
note: found an item that was configured out
--> /home/runner/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/syn-2.0.104/src/lib.rs:485:15

485 | FieldPat, Pat, PatConst, PatIdent, PatLit, PatMacro, PatOr, PatParen, PatPath, PatRange,
| ^^^
note: the item is gated behind the `full` feature
--> /home/runner/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/syn-2.0.104/src/lib.rs:482:7
|
482 | #[cfg(feature = "full")]
| ^^^^^^^^^^^^^^^^
```
## Solution
- Enable the `full` feature of `syn`
