Molecular modeling often requires precise visualizations to communicate complex concepts effectively. This process can be challenging, especially when dealing with large molecular structures or intricate mechanisms. One common issue modelers face is managing the visibility of objects, such as structural or visual models, meshes, and labels. Being able to gradually control their transparency can make a huge difference in presentations or molecular animations. That’s where SAMSON’s Disappear animation comes in to save the day.
What is the Disappear Animation?
The Disappear animation in SAMSON allows users to make selected nodes progressively disappear. This feature is particularly effective for nodes with a transparency attribute—such as structural models, visual models, meshes, and labels. Nodes without a transparency attribute, like individual atoms and bonds, will essentially behave like they are hidden, akin to SAMSON’s Hide animation.
This feature is especially handy when creating animations to highlight molecular processes, structural transitions, or step-by-step mechanisms. Being able to control transparency dynamically ensures that presentations and visualization videos can tell a clearer story to the audience without visual clutter.
How to Add the Disappear Animation
Creating a Disappear animation in SAMSON is straightforward:
- Select the nodes you want to make progressively transparent.
- Double-click the Disappear animation effect in the Animation panel of the Animator.
The Disappear animation consists of four keyframes:
- Keyframe 1 to Keyframe 2: The nodes remain fully opaque.
- Keyframe 2 to Keyframe 3: Transparency of the nodes increases progressively.
- Keyframe 3 to Keyframe 4: The nodes become fully transparent.
You can freely move the keyframes in the timeline to customize when and how transparency changes occur. This flexibility means that animations can be tailored precisely to fit your workflow or storytelling needs.
Note: If you need to modify how parameters (e.g., transparency) transition between frames, you can edit the Easing curve. This gives advanced users even more control over the animation behavior.
A Practical Example
The Disappear animation is particularly useful for highlighting specific regions within a larger molecular structure. For instance, when focusing on a ligand within a protein binding site, you can gradually make the surrounding residues disappear. This isolates the ligand while elegantly transitioning the background out of view, ensuring that your audience fully grasps the subject of interest.

Conclusion
Whether you’re creating a presentation, designing an educational video, or simulating molecular events, the Disappear animation in SAMSON offers a simple way to control the visibility of structures without disrupting the overall visual flow.
