The attached geometry collection is blown up

If i attach a geometry collection to the end of a static mesh and try to simulate physics on the static mesh, it will spin and be blown off somewhere.

There is no collision between the two, the static mesh is heavier, and the geometry collection is set to Static.Furthermore, the fractured fragments appear to be affected by the movement of the parent.

How can I maintain the parent-child relationship between GC and static meshes while simultaneously performing physics simulations of fractures?

Hi

Do you have more detail on how you attach the static mesh and the geometry collection ?
Are you using a physics constraint component or are you using the actor to actor attachment system ? if the later, who is the parent and who is the child actor ?
