int32 TileCount
How many tiles should the resulting movie render be broken into? A tile should be no larger than the maximum texture resolution supported by your graphics card (likely 16k), so NumTiles should be ceil(Width/MaxTextureSize). More tiles mean more individual passes over the whole scene at a smaller resolution which may help with gpu timeouts. Requires at least 1 tile. Tiling is applied evenly to both X and Y.
