void SetInstanceSimulatePhysics
&40;
bool bSimulate,
bool bMaintainPhysicsBlending,
bool bPreserveExistingAttachment
&41;
Remarks
Set this body to either simulate or to be fixed/kinematic.
Parameters
| Name | Description |
|---|---|
| bMaintainPhysicsBlending | If true then the physics blend weight will not be adjusted. If false then it will get set to 0 or 1 depending on bSimulate. |
| bPreserveExistingAttachments | If true then any existing attachment between the owning component and its parent will be preserved, even when switching to simulate (most likely useful for skeletal meshes that are parented to a moveable component). If false then the owning component will be detached from its parent if this is the root body and it is being set to simulate. |
