# D3D12_TEX2D_ARRAY_SRV

> Describes the subresources from an array of 2D textures to use in a shader-resource view. (D3D12_TEX2D_ARRAY_SRV)

Describes the subresources from an array of 2D textures to use in a shader-resource view.

## Syntax

```cpp theme={null}
typedef struct D3D12_TEX2D_ARRAY_SRV
{
    UINT MostDetailedMip;
    UINT MipLevels;
    UINT FirstArraySlice;
    UINT ArraySize;
    UINT PlaneSlice;
    FLOAT ResourceMinLODClamp;
} D3D12_TEX2D_ARRAY_SRV
```

### Members

*MostDetailedMip*\
Type: UINT

Index of the most detailed mipmap level to use; this number is between 0 and **MipLevels** -1 (where **MipLevels** is from the original Texture2D for which [ID3D12Device::CreateShaderResourceView](/reference/graphics/d3d12/interfaces/id3d12device/methods/id3d12device_createshaderresourceview_public) creates a view).

*MipLevels*\
Type: UINT

The maximum number of mipmap levels for the view of the texture. See the remarks in [D3D12\_TEX1D\_SRV](/reference/graphics/d3d12/structs/d3d12_tex1d_srv_public).

Set to -1 to indicate all the mipmap levels from **MostDetailedMip** on down to least detailed.

*FirstArraySlice*\
Type: UINT

The index of the first texture to use in an array of textures.

*ArraySize*\
Type: UINT

Number of textures in the array.

*PlaneSlice*\
Type: UINT

The index (plane slice number) of the plane to use in an array of textures.

*ResourceMinLODClamp*\
Type: FLOAT

Specifies the minimum mipmap level that you can access. Specifying 0.0f means that you can access all of the mipmap levels. Specifying 3.0f means that you can access mipmap levels from 3.0f to *MipCount - 1*.

We recommend that you don't set *MostDetailedMip* and *ResourceMinLODClamp* at the same time. Instead, set one of those two members to 0 (to get default behavior). That's because *MipLevels* is interpreted differently in conjunction with different fields:

* For *MostDetailedMip*, mips are in the range \[*MostDetailedMip*, *MostDetailedMip* + *MipLevels* - 1].
* For *ResourceMinLODClamp*, mips are in the range \[*ResourceMinLODClamp*, *MipLevels* - 1].
