I want to model a shrub, and use Particle Flow(preferably)or a scatter modifier to make it happen. I was thinking make a box and use it as the surface to array on. I also made a planar leaf to start. When I used PFlow I can’t get the objects to be perpendicular to the surface they are being generated on. Meaning, an object generated on the side is laying flat, and an object on the top of the box is also laying flat. Which also causes problems with rotation, scale...etc.  I hope i explained this good enough for anyone to help out. Thanks.

Try using these operators in this order (the order of the operators is sometimes important in pflow) in your setup:

Speed By Surface
Rotation
Speed

-Set the speed by surface to use your box as the surface geometry and change the direction to out of surface
-Have the rotation operator use speed space for the orientation
-Give the speed operator a value of 0.

The idea is the speed by surface sets the trajectory to perpendicular to the surface of the box for the rotation operator to use to change the rotation of the particles. The regular speed operator is there because there needs to be some value in the speed by surface operator for it to work and having the speed operator set to 0 will cancel any movement.

thank you for the response, And sorry for my delayed one. I will give that a shot and let youknow if it works
