I used 2 photos to create the branch and set as backgrounds in the viewport ( for creating background in the viewport create two planes one for the front and other for the top view and apply a references photos as material ) 我使用2张图片来创建树枝并在视图中将它们设置为背景(为了在视图中创建出背景,需要创建两个平面,一个作为前视图,另一个作为顶视图,并且将图片指定为材质) 。
