Mips generation for texture loaded from file at runtime.

Hi,

I know how create a texture from file with ImageWrapperModule and UTexture2D::CreateTransient and then assign it to a MID.


  • Texture = UTexture2D::CreateTransient(SizeX, SizeY, Format);
    FTexture2DMipMap& Mip = [Texture]->PlatformData->Mips[0];
    void* Data = Mip.BulkData.Lock( LOCK_READ_WRITE );
    FMemory::Memcpy( Data, DataReadFromFile, DataSize );
    Mip.BulkData.Unlock( );
    Texture->UpdateResource();*

Now, how can I auto generate mips for the texture?

Thanks.
