I have a question about fractures in Geometry Collection.

How can you accurately fracture a solid object with holes, like a wall with windows?

I saw a tutorial somewhere before that said you should slice along the window frame to create a convex collision.

I sliced ​​the wall horizontally twice, dividing it into four parts, as shown in the image.

However, even if i create convex collisions with slicing, there will still be collisions inside the window frame.

In the dataflow, Voronoi fracture is performed after the Planner.

I tried changing the order and running Flatten, but the collision inside the window frame did not disappear.

How can I fracture a wall while still leaving a window hole?
