This lesson introduces the Populate tool, which provides an easy way to people a scene with animated characters. In this tutorial, you will learn how to:. Skill level: Intermediate. Set up the scene:. The scene is an urban area with a street, sidewalks, and a pedestrian walkway.
Add a pedestrian flow for the far sidewalk:. The Ribbon's Populate tab contains a variety of controls for the Populate tool. Additional controls appear on the Modify panel. The scene is measured in feet, so the flow will be 12 feet wide.
Add a flow for the crosswalk and walkway:. Foot traffic on the pedestrian walkway will be a little narrower than on the main sidewalk. Notice how Populate displays four-way arrows where the flows cross each other.
It is important to make sure these arrows appear: If you don't see them, it means the flows did not intersect correctly. When the intersection is incorrect, pedestrians on one flow might walk through pedestrians on the other! The angle between intersecting flows can be between 45 and degrees.
Pedestrians that encounter the intersection sometimes change direction and turn left or right instead of continuing ahead.
Add a flow for the near sidewalk:. Create the Populate simulation:. Populate's simulation feature is a global control that applies to all flows in the scene. Placeholders for characters are present from the start: You can see them as small red and blue icons on the flows you created, and if you scrub the time slider, you can see that the placeholders are already animated. The "tail" on each placeholder icon shows the direction in which the character is facing.
Red characters are women and blue characters are men. After some calculation time, Populate places animated characters in the placeholder locations. While it creates the simulation, a progress bar appears in the status line area at the bottom of the 3ds Max window. When the calculation is complete, the sidewalks, crosswalks, and walkway have people walking along them. You can scrub the time slider or click Play to watch the animation.
The image in the shaded Camera view might degrade quickly, though, because there is now a lot of geometry in the scene. Increase the density of the foot traffic:. As you can see, this rollout lets you adjust other aspects of the animation, such as the balance between men and women. Leave Flow, on the near sidewalk, as it was.
Not much of that flow is visible to the camera, anyway. This time, the status bar indicates that Populate is creating more pedestrians than it did the first time. When the calculations are done, the scene has more of the look of a city at midday. Add some seated people to the scene:. Not everybody is in a hurry to go somewhere. Along with pedestrians, the Populate tool lets you add characters who are sitting or standing.
Like pedestrian flows, seats are helper objects that do not render. By default, the seats face up along the viewport's Y axis the wider side of the seat geometry is the front of the seat.
This does not match the bench geometry. When seated people face each other, as the two lower seats are placed in the example, then by default the characters interact with each other. Wireframe viewports indicate this by displaying a line between the seats that interact. You can make an interacting seated character behave as if alone by turning on the Single checkbox on the Seat rollout.
In this long shot, the seated characters are hard to see. In the Camera medium shot the new seated figures show up well. Add standing idlers:. Within the viewport display of the idle area, the circles show conversations between two or three characters.
Characters not on the edge of a circle are solitary. The Idle Area rollout has even more adjustments than the Flow rollout, but the default values are fine for this simulation. Now the corner of the walkway contains characters conversing or spending time by themselves. Characters in an idle area are animated too, but they do not travel. Increase the length of the animation:. At frames, the current animation is too short to show many—if any—pedestrians turning corners at the intersections of the flows.
Increasing the length of the animation increases the chance of this happening. Simulate resimulates the Populate animation, and also increases the number of frames in the scene to Now there is a greater chance of seeing pedestrians turn corners. There is also a greater chance of the viewport display degrading, because of memory use. Optional Increase the length of the flag animation:. You might notice a glitch in using Populate Simulate to extend the animation length: The flags above the walkway cease to move at the original animation length of frames.
You can correct this as follows:. The motion of the flags still winds down, as the only force acting on them is gravity. But the motion does continue beyond frame Save your work:. The full animation takes a long time to render. You can play this movie to see a version of the Populate simulation:.
Populate provides a quick and easy way to add animated characters to a scene. Characters can increase the warmth and realism of architectural models. The features of Populate covered in this tutorial include:. Some features of Populate that this introduction does not cover are:. You might want to experiment on your own. The Populate tool adds pedestrians and standing or sitting idlers to a scene.
See Where to Find Tutorial Files. Rendering of the initial scene. Pedestrian flow that parallels the far sidewalk. Note: Although we don't use the technique in this tutorial, when you create flows you can create multiple segments by dragging the mouse again after each click.
Right-click when you are done. A second flow for the crosswalk and walkway intersects the first. Flow for the near sidewalk intersects the flow from the crosswalk. You can also switch characters to High Resolution Skin for close-up renderings. This tutorial uses the default low-resolution Textured Skin, which is adequate for long views such as the Camera view. Tip: It is hard to select flows by clicking in the shaded Camera view.
Use the Top view, or select the flow by name. Summary Populate provides a quick and easy way to add animated characters to a scene. The features of Populate covered in this tutorial include: Adding Flow objects that define where pedestrians walk.
Creating flows that intersect, allowing pedestrians to turn right or left, or just continue in the same direction unless the flow is T-shaped and the character has to turn. Adjusting the Density value to increase the number of pedestrians. Creating seated idlers. Creating an Idle Area with standing characters that remain in the same place.
Some features of Populate that this introduction does not cover are: Creating flows that change direction, with multiple segments. Adding runners to a flow. Adding a ramp to a flow. Editing idle areas. Using Regenerate Selected to update the appearance of some characters.
