# ENTITY::_IS_BATCH_MODEL

- **Hash:** `0xD4636C2EDB0DEA8A`
- **Namespace:** ENTITY
- **Runtime name (Lua/JS):** `IsBatchModel`
- **Side:** client (game native)
- **Name status:** community guess (may change)
- **Documentation:** described
- **Since game build:** 1207
- **Other names:** `_IS_MODEL_IN_NEED_OF_VEG_MODIFIER`
- **URL:** https://natives.borderlinerp.com/natives/ENTITY/_IS_BATCH_MODEL

## Signature

```c
BOOL _IS_BATCH_MODEL(Hash model);
```

## Parameters

- `model` (`Hash`)

## Returns

`BOOL`

## Description

*Source: alloc8or RDR3 NativeDB*

Returns whether the model's map entity type is MAP_ENTITY_TYPE_GRASS_BATCH or MAP_ENTITY_TYPE_PROP_BATCH.

Scripts use the result to choose how to hide a single model, since batched geometry is not removed through the normal model-hide path:
- TRUE: GRAPHICS::ADD_VEG_MODIFIER_SPHERE / REMOVE_VEG_MODIFIER_SPHERE
- FALSE: ENTITY::CREATE_MODEL_HIDE / CREATE_MODEL_HIDE_EXCLUDING_SCRIPT_OBJECTS / REMOVE_MODEL_HIDE

Not limited to foliage: many natural world models return TRUE (rocks, trees, bushes, grass, crops, branches, roots, logs, debris), as well as ambient vfx batches such as butterflies, dragonflies, and fireflies.

Checks whether the specified model can be handled through the vegetation modifier path.
This is not limited strictly to foliage. Testing shows many natural world
models can return TRUE, including rocks, trees, bushes, grass, crops, branches, roots, logs, debris, and similar environment assets.

## Usage

### Lua

```lua
local retval = IsBatchModel(model)

-- always available, by hash
local retval = Citizen.InvokeNative(0xD4636C2EDB0DEA8A, model, Citizen.ReturnResultAnyway())
```

### JavaScript

```js
const retval = IsBatchModel(model);

// by hash
const retval = Citizen.invokeNative('0xD4636C2EDB0DEA8A', model, Citizen.returnResultAnyway());
```

### C#

```csharp
bool retval = Function.Call<bool>((Hash)0xD4636C2EDB0DEA8A, model);
```

- Hash parameters: the named function also accepts a string and hashes it for you; `Citizen.InvokeNative` needs the number — pass `joaat("name")` or a backtick literal like `` `name` ``.
- The name is a community guess and may change. If the named call is missing in your client build, use `InvokeNative` with the hash — it always works.
