Note: When you convert a layer into a smart object, you can no longer edit it directly (e. g., you can't use the Brush Tool to paint on the layer).

注意：当你转换一个图层为智能对象，你就不能再直接编辑它了(举例：你不能用画笔工具在图层上涂抹)。

So, instead of creating a NULL_BRUSH, I created a pattern brush by using a chunk of bitmap from where the edit control is going to be shown.

所以我不是创建了一个NULL_BRUSH，而是通过用编辑框所在区域的位图创建了一个模式刷。

Choose Brush Tool again to picture the butterflies. Place them on different angles, but they must be of different dimensions (Edit? Free Transform).

选择笔刷工具，绘制一些不同角度的蝴蝶，角度可以使用编辑-自由变换来进行调整。
