Method DownloadVertexBuffer

Source/Engine/Graphics/Models/Mesh.cs:505–538

Downloads the raw vertex buffer that contains mesh vertices data. To download data from GPU set to true and call this method from the thread other than main thread (see ). [Deprecated in v1.10] If set to true the data will be downloaded from the GPU, otherwise it can be loaded from t

        /// <param name="forceGpu">If set to <c>true</c> the data will be downloaded from the GPU, otherwise it can be loaded from the drive (source asset file) or from memory (if cached). Downloading mesh from GPU requires this call to be made from the other thread than main thread. Virtual assets are always downloaded from GPU memory due to lack of dedicated storage container for the asset data.</param>
