Chaos Cache Manager not showing the facture with Static Pose

Development World Creation

In my newly generated level, I added a sphere. In Fracture Mode, I saved this as a Geometry Collection and added a layer of fracture. I then created a Chaos Cache Manager and created and linked a new Chaos Cache Collection. Under Observed Components, I added the sphere.

I set the Chaos Cache Manager to record and watch my sphere fall to the ground and fracture. If I set the Chaos Cache Manager to play and press simulate, I see the ball broken as well. If I set the Chaos Cache Manager to Static Pose and want to select the end via Start Time, I see that the recording goes up to the breaking of the ball. The breaking of the ball cannot be seen.

I have watched several tutorials on Chaos destruction and I cannot find what I am doing wrong. Does anyone have some tips?

just disable nanite for that mesh, it’ll work, probably, just try

Issues with Nanite Geometry collections and static pose got fixed in 5.6

Here’s the reference to the corresponding commit in the Unreal Github
https://github.com/EpicGames/UnrealEngine/commit/59729c7c24f5774c1d068ed86c541f0c9c028f38
it changes the UGeometryCollectionComponent::RestTransformsChanged() function

I have the same issue, even tried to disable nanite on the mesh

I have the same issue too, nanite disable on the mesh too. But the fracture animation is not showing in static pose. Only working in lecture mode.

Same issue here! How could we send this back up to unreal dev as a bug ?

Hi, I’ve tried using UE 5.6.1. Now, the fracture works in a static pose and can be displayed in the sequencer, but I still have the same issue when rendering: the mesh doesn’t fracture.

Mine can fracture and record but will not playback. ive seen the same issue across a few different threads. Chaos cache manager just seems to be broken in 5.6
