Functions Summary
	int	GetNumFragments () con)
	int	GetNumVisibleFragments () con)
	array<byte>	GetVisibleFragments () con)
	bool	IsFragmentVisible (INT FragmentIndex) con)
	bool	SetStaticMesh (StaticMesh NewMesh, optional bool bForce)

bInitialVisibilityValue Source code

Initial visibility value for this component.

bResetStaticMesh Source code

TRUE whenever the static mesh is being reset during Reattach

bUseDynamicIBWithHiddenFragments Source code

If true, bUseDynamicIndexBuffer will be enabled when at least one fragment is hidden, otherwise it will be disabled. If false, bUseDynamicIndexBuffer will not be overridden.

bUseDynamicIndexBuffer Source code

If true, each element will be rendered with one draw call by using a dynamic index buffer that is repacked when visibility changes. If false, each element will be rendered with n draw calls, where n is the number of consecutive index ranges, and there will be no memory overhead.

bVisibilityHasChanged Source code

If true, VisibleFragments has changed since the last attach and the dynamic index buffer needs to be updated.

bVisibilityReset Source code

True if VisibleFragments was reset to bInitialVisibilityValue since the last component attach.

ComponentBaseResources Source code

This component's index buffer, used for rendering when bUseDynamicIndexBuffer is true.

NumResourceIndices Source code

Number of indices in the resource's index buffer the last time the component index buffer was built. Used to detect when the resource's index buffer has changed and the component's index buffer should be rebuilt.

ReleaseResourcesFence Source code

A fence used to track when the rendering thread has released the component's resources.

VisibleFragments Source code

Stores non-zero for each fragment that is visible, and 0 otherwise.

GetNumFragments Source code

Get the number of chunks in the assigned fractured mesh.

GetNumVisibleFragments Source code

Get the number of chunks that are currently visible.

GetVisibleFragments Source code

Returns array of currently visible fragments.

IsFragmentVisible Source code

Returns whether the specified fragment is currently visible or not.

SetStaticMesh Source code

Change the StaticMesh used by this instance, and resets VisibleFragments to all be visible if NewMesh is valid.
@param NewMesh - StaticMesh to set. If this is not also a UFracturedStaticMesh, assignment will fail.
@return bool - TRUE if assignment succeeded.
