How to: Scatter an object over a random
surface in 3ds Max
TUTORIALS
In this tutorial, you will be learning how to scatter an object over a random surface in 3ds
max. I saw many beginners lost when it comes to distribute objects over a random
surface. Placing each object manually over the surface and taking time to adjust every
object is not a good idea at all.
This tutorial will teach you how to do this in a better way using Scatter compound object
with complete usage of Scatter’s other powerful options. So let’s get into it.

Here, I have a normal
Plane
with bend modifier applied to it and a
Box
in the scene. We
will be using the
Plane
as the distribution object and a
Box
as source object.

Let’s select the box and go to
Create > Compound Objects > Scatter.
Now, under
Pick
Distribution Object
rollout, click on the
Pick
button and pick the sphere as the
distribution object.
Under
Source Object Parameters
group, set the
Duplicates
value according to your
need.
You can control the size / scale of the duplicate objects by adjusting the
Base Value.
Vertex Chaos
is just to give some randomness to the vertices of the object.

You can choose the distribute type using some options available under
Distribution
Object Parameter
group. I am using Even for this case.
Perpendicular
option, when on, orients the duplicate object according to the orientation
of the component (vertex, edge or face) of the distribution object.
Use Selected Faces
option allows you to distribute objects over the selected faces of the
distribution object.
Area
This option scatters the duplicate objects evenly on the entire surface.
Even
This option divides the number of faces in distribution object by the number of duplicate
objects and skips the suitable number of faces during the distribution process.
Skip N
It skips the
N
(whatever number you specify in the spinner) number of faces during the
process of distributing duplicate objects.
Random faces
This option distributes the duplicate objects randomly on the distribution object.

Along Edges
This option distributes the duplicate objects randomly on the edges of the distribution
object.
All Vertices
This option places the duplicate object on all the vertices of the distribution object.
No matter how many duplicates you are using for distribution, it just covers all the
vertices as it doesn’t depends on the
Duplicates
parameter. You can notice, while using
this option, the
Duplicates
spinner greyed out (disabled).
All Edge Midpoints
This option lets you distribute duplicate objects over the mid-points of the edges of the
distribution object.
All Face Centers
This option distributes duplicate objects on the center of the faces of the distribution
object.
Volume
This option distribute the duplicate objects as per the volume of the distribution object.
Note: All vertices, All Edge Midpoints and All Face Centers options ignore the
Duplicates parameter and distribute the duplicate objects according to the number
of vertices, edges and faces of the Distribution Object.
