Hi,

 

I have a DDS CubeMap texture in the memory: 64x64, depht: 1, mipmaps: 7, format: BC3_UNorm_SRgb.

It's stored as 6 * 7 data blocks.

I trying to create a texture:

using (SafeUnmanagedArray array = new SafeUnmanagedArray(gtex.MipMapData.Sum(d => d.Length)))
{
    DataBox[] rects = new DataBox[gtex.MipMapData.Length];
    using (UnmanagedMemoryStream io = array.OpenStream(FileAccess.Write))
    {
        byte[] buff = new byte[32 * 1024];
        for (int index = 0; index < gtex.MipMapData.Length; index++)
        {
            GtexMipMapLocation mimMap = gtex.MipMapData[index];
            Int32 rowPitch, depthPitch;
            GetPitch(descriptor, index % descriptor.MipLevels, out rowPitch, out depthPitch);

            rects[index] = CreateDataBox(array, io, rowPitch, depthPitch);
            input.SetPosition(mimMap.Offset);
            input.CopyToStream(io, mimMap.Length, buff);
        }
    }

    Texture3D texture = new Texture3D(_device, descriptor, rects);
    return new DxTexture(texture, descriptor);
}

But get an invalid MiscFlags exception (0x6). I think the problem in the wrong formation of DataCubes.

Or invalid depthPitch.
