Photoshop's oblique filter is set through the direction parameter, which is not difficult in flash. You only need to change the highlighted color and the shadow color, or change the angle, you can set one of the distance values to a negative number. (See Figure 3.46 ~ Figure 3.48) (Note: I added a projection filter to the bottom)

Figure 3.46 The concave effect is achieved by switching the highlighted and shadow colors.

 

Figure 3.47 sag is achieved by setting the distance to a negative number

 

Figure 3.48 sag is achieved by setting the angle to a negative number (225 degrees and-135 degrees are equivalent)
