Twinmotion Direct Link SketchUp Meshes Missing From Scene

Twinmotion 2025.2
SketchUp 2026 (Direct Link plugin)

I’ve reopened a Twinmotion file which I was working on last week and a bunch of meshes from my SketchUp model have disappeared. They are in the Scene Graph, but not visible in the viewport or in any media views. See attached example, most groups/components that make up the window on the right are not visible.

I have attempted resyncing with Direct Link, changing materials to two-sided, reimporting deleted objects - nothing is bringing back the missing meshes.

This has happened on other projects with other files before, I would be very grateful if someone could help me understand what has gone wrong and how to fix/prevent it in future.

For anyone else who has the same issue, I’ve just discovered that exploding/ungrouping then making a new component/new group in sketchup before resyncing fixes the issue.
