Distributing objects in 3ds Max can be efficiently handled using specialized tools designed for placing multiple instances of an object along paths, edges, or surfaces, or between specific points.
Using the Spacing Tool
The Spacing Tool is one of the most common methods for distributing objects evenly or with specific spacing in 3ds Max. It allows you to place multiple copies of a selected object along a defined path (like a spline or edge) or between two picked points.
Here’s how it generally works:
- Select the Object: Choose the object you want to distribute.
- Open the Tool: Navigate to Tools > Spacing Tool.
- Pick the Path/Points:
- Use the Pick Path button to select a spline or an edge sub-object. The objects will be distributed along this path.
- Use the Pick Points buttons to select two points in your scene. The objects will be distributed along a straight line between these points.
Key Spacing Tool Options
The Spacing Tool offers several parameters to control the distribution:
-
Count: Specifies the total number of objects to place.
- Insight: As mentioned in the reference, if you specify more than two objects, 3ds Max evenly distributes the objects between the offsets (or along the path). The tool calculates the necessary spacing to fit the specified count evenly from the start to the end of the path or between the points.
-
Spacing: Specifies the distance between the pivot points of the distributed objects.
- Insight: You can choose to distribute by Spacing instead of Count.
-
End Offsets: Define a distance from the start or end of the path/points where distribution should not occur.
-
Distribution: Controls how spacing is applied.
- Evenly: Distributes objects uniformly along the path or between points.
- Centering: Aligns the center of the distributed object array with the path/points.
- Space from Center: Defines spacing from the center point.
- Space from End, Unbounded: This specific method, highlighted in the reference, Distributes the number of objects you specify along a straight line from the end toward the start of a spline or a pair of points. You specify the spacing between objects. This means you define both the number of items and the gap between them, potentially extending beyond the defined path/points if the spacing is large.
-
Follow: Makes the distributed objects orient themselves according to the direction of the path.
-
Type of Object: Choose whether to create Copies, Instances, or References of the distributed object.
-
Example: You could use the Spacing Tool to quickly place fence posts along a property line (using Pick Path on a spline) or create a row of lights along a ceiling edge (using Pick Edges and Follow).
Other Distribution Methods in 3ds Max
While the Spacing Tool is excellent for linear or path-based distribution, 3ds Max provides other methods for different scenarios:
Array Tool
The Array tool (Tools > Array) allows you to create multiple copies of an object in radial, linear, or grid patterns based on incremental transformations (Move, Rotate, Scale).
- Use Case: Creating steps on a spiral staircase (radial array), duplicating windows on a facade (grid array), or making multiple copies of a single item in a straight line (linear array).
Scatter
The Scatter compound object allows you to distribute source objects randomly or uniformly across the surface of a distribution object.
- Use Case: Placing trees on a landscape, distributing pebbles on the ground, or scattering leaves on a path.
Particle Systems
For dynamic or complex distributions, particle systems can be used to emit instances of objects (like trees, rocks, etc.) onto surfaces or within volumes.
- Use Case: Creating dynamic crowds, distributing rain drops, or populating complex environments based on rules.
Manual Placement
For simple, unique, or non-uniform distributions, you can, of course, manually duplicate and position objects using standard transformation tools.
Choosing the right method depends on the desired outcome, the complexity of the distribution, and the nature of the path or area you're distributing objects onto.
