The chunks that remain connected to the parent physics geometry via bonds remain rigidly connected to the physics body. When bonds are damaged, chunk islands that are not connected via bonds to the parent physics geometry become separate dynamic bodies. When simulating, the destructible mesh will move with its parent physics as a single rigid body.

Press the Recalculate Attachment buttonīonds will be formed with any adjacent or overlapping collision geometry from the same rigid Body.

The same rules apply as for Static Attachment above This will automatically set the contained meshes as collidersĬlick the Fracture Selected button to fracture the mesh as usual Navigate to Physics > Apply Preset > Rigid Body

Set the hierarchy as dynamic and collideable.

The chunks that remain connected to static geometry via bonds remain kinematic.Ĭreate a Xform prim to contain the meshes with Create > XformĬreate/load meshes and add them to the Xform container When bonds are damaged, chunk islands that are not connected via bonds to static geometry become separate dynamic bodies. When simulating, the bonds formed keep the destructible “static” (kinematic). Press the Recalculate Attachment button to form bonds between the destructible and nearby static geometry (“external” bonds)ĭebug visualization > Internal Visualization shows where external bonds have been formed when set to Selected or All When unchecked, the chunks can take damage and break free, becoming new dynamic rigid bodies This is a good idea if the Blast container is deeply penetrating the static geometry, otherwise physics will force them apart when the pieces become dynamic When checked, the base pieces will remain kinematic no matter how much damage they take

Set the state of Make External Bonds Unbreakable based on how you want the base to behave.

Place the destructible prim adjacent to (or slightly overlapping) a static collision mesh

Leave the source prim as dynamic, do not set to kinematic or static

Create a destructible prim in the usual way (see Getting Started above).Navigate to Physics > Apply Preset > Collider
