When preparing a molecular scene for a presentation, the camera often needs to travel along a structure so the viewer can follow it. A common frustration is that changing the view can also change what stays centered: the model drifts out of frame, or the camera move feels more like a rotation than a smooth translation.
In SAMSON, the Pedestal camera animation is designed for a vertical camera move. It shifts the camera’s position and target point together, in parallel, between two keyframes. Because both move, the view can travel vertically while keeping its direction of aim. This is useful when you want to reveal different regions of a molecular assembly without manually repositioning the camera at every moment.
Set up the move around the view you want
- Choose the start frame. In the Animator’s Track view, place the playhead where the camera move should begin.
- Compose the starting view. Orient the camera as you want the animation to begin. Take a moment to check which part of the structure is centered and how much of the model is visible.
- Add Pedestal camera. Double-click the effect in the Animator’s Animation panel. The camera’s current position and target point are used for the start frame.
- Set the end frame. Choose how long the move should take by setting the animation’s end frame. At the end, the camera position and target point are both shifted vertically upward by the same distance.
The key idea is that this is a move of the view, not a request to make the camera look at a different point while remaining in place. If your goal is to shift the framing horizontally instead, the related Truck camera animation moves in the horizontal direction. For other kinds of camera changes, see Move camera.
Make the result easier to read
Before adding the animation, decide what the viewer should notice at the beginning and end. For example, you might start with a broader view of a complex and finish with a region higher in the scene. The camera move can connect those views, but it does not decide which biological feature matters; that composition is established by your starting view and the animation’s vertical displacement.
Scrub through the animation after setting its frames. If the transition happens too quickly or slowly for the scene, adjust the spacing between the start and end frames. You can also change the easing curve to control how camera parameters are interpolated between frames. This lets you refine the pacing without changing the basic purpose of the move.
Check the camera settings
By default, camera animations apply to the active camera. If you need the animation to affect a different camera, inspect the animation and adjust Apply to active camera. The animation’s target point is based on the active camera’s current target position, which is essentially the center of the view. Setting up the desired composition before adding the effect therefore helps establish the intended starting point.
The camera’s behavior can also depend on whether the grid is on or off. Inspect the animation’s Keep camera upwards option to control this behavior. If the camera does not move as expected after changing the grid setting, check this option as part of your review.
You can adjust camera positions and target points with animation controllers, although Pedestal camera has specific limitations on how those values can be adjusted. If a controller does not allow the edit you expect, the effect’s constraints may be the reason. You can move the animation’s start and end frames whenever needed.
For a vertical camera move that keeps the camera and its target traveling together, Pedestal camera offers a simple way to make a molecular scene easier to follow. For the full instructions and details, see the Pedestal camera documentation.
