Hello
It sounds like you may be experiencing an issue with the Continuously Rasterize (or Collapse Transformations) setting in After Effects.
When Continuously Rasterize is enabled for a layer, it allows the layer to maintain its sharpness and resolution regardless of how much it is scaled or zoomed in on. However, if there are other effects or settings applied to the layer, such as the Smoothing setting you mentioned, it can cause the layer to disappear or reappear when zooming in.
To fix this issue, try the following:
Make sure Continuously Rasterize is turned off: Select the layer in question, and look for the Continuously Rasterize (or Collapse Transformations) switch in the layer’s switches panel. If it is turned on, turn it off and see if that resolves the issue.
Adjust the layer’s scaling: If the layer is still disappearing when zooming in, try adjusting its scaling or position to see if that helps. Sometimes, the issue can be caused by the layer being too small or off-screen when zoomed in.
Check other layer settings: If the issue persists, check the layer’s other settings, such as its opacity or blending mode, to see if any of them are causing the problem.
If none of these solutions work, you may want to reach out to the Adobe support team for further assistance
