## Motion vectors for transparent objects

By default, HDRP does not render motion vectors for transparent Materials. This is because motion vectors from transparent GameObjects overwrite motion vectors for GameObjects behind them. For example, a window would overwrite the motion vectors for a bird flying behind it.
By default, HDRP does not render motion vectors for transparent Materials. This is because motion vectors from transparent GameObjects overwrite motion vectors for GameObjects behind them. For example, a window would overwrite the motion vectors for a bird flying behind it. In this example, since the bird's motion vectors are now invalid, if you used [temporal anti-aliasing](Anti-Aliasing.md#temporal-anti-aliasing-taa), the bird would produce ghosting.

To make HDRP render motion vectors for transparent Materials, see the steps in [Using motion vectors](#using-motion-vectors) and enable **Transparent Object Motion**.
