In this video, you will learn about the Vegetation Painter tool in Twinmotion. The vegetation painter allows you to select one more piece of vegetation and place them in your project as though you are painting them on. This becomes its own element with its own properties and setting that can be updated or manipulated as you paint or even coming back later. You can add or remove multiple pieces of vegetation to a completed vegetation paint.
