I’m trying to create an array of DepthStencil views from a Texture2DArray in Direct3D, and I’m running into some issues. I’ve followed a similar process for a TextureCube, so I thought I’d be on the right track, but here I keep encountering exceptions that I just can’t pinpoint.

Here’s the breakdown of what I’ve done so far:

1. I successfully created a texture for depth stencil that’s a texture2Darray with an array size of 3. That part worked perfectly.
2. I managed to create a depth stencil view from the texture. No problems there either.

Now, the next step is where I hit a snag. I want to create an array of depth stencil views so that I can render to them individually without relying on a geometry shader. Here’s where I made the change. Instead of using my previous method for creating the depth stencil view, I’ve switched to this new approach, which I’ve included below:

“`cpp
ID3D11DepthStencilView* CreateDepthStencilView2DFromArray(ID3D11Texture2D* pText2D, DXGI_FORMAT Format, DWORD Slice)
{
ID3D11DepthStencilView* pDSV = NULL;
D3D11_DEPTH_STENCIL_VIEW_DESC descDSV;
ZeroMemory(&descDSV, sizeof(descDSV));
descDSV.Format = Format;
descDSV.ViewDimension = D3D11_DSV_DIMENSION_TEXTURE2DARRAY;
descDSV.Texture2DArray.FirstArraySlice = Slice;
descDSV.Texture2DArray.ArraySize = 1;
descDSV.Texture2DArray.MipSlice = 0;
HRESULT hr = gpD11->CreateDepthStencilView(pText2D, &descDSV, &pDSV);
if (FAILED(hr)) return NULL;
return pDSV;
}
“`

I’ve set MipSlice to 0 since I’m not using mipmaps at all. However, I keep getting a first chance exception error, and I can’t figure out what’s going wrong. I’m passing the correct parameters to the function, including a valid Texture2DArray and the right format, but it’s just not working.

Could it be something specific about how I’m setting the DSV description, or is there another underlying issue that I might be overlooking? Any guidance would be hugely appreciated!
