Physics Fields do not act reliably on Geometry Collections

Hi everyone,

I’ve been struggling and have found that physics fields don’t act reliably and consistently on Geometry Collections.

This is making it impossible to create an environment that reacts to forces predictably.

Below I have used the engine’s own master field (FS_MasterField) and Anchor Field (FS_AnchorField_Generic) to demonstrate the issue. The structures are my own from Blender, however the cylinder on the left I generated in Unreal Editor.

Left: The cylinder breaks about the location of the field. Centre Left: The wall ignores the stress field. Centre Right: The turret has a ring that falls off but otherwise ignores the stress field. Right: The tower disintegrates completely except within the anchor field.

The cylinder is the only Geometry collection to respond properly and logically to the physics field.

The other structures have their own responses that don’t make any sense.

Damage settings are default for all Geomtery Collections (except for Damage Propagation: 0.001).
All physics fields use the Engine’s default settings with added delay (15s).
All actors were created in, and imported from Blender using the same method.
