UBlendSpace::GetResourceSizeEx

function Engine Since 4.0

#include "Animation/BlendSpace.h"

Access: public Specifiers: virtualoverride

Description

Reports the blend space's estimated memory footprint by accumulating into CumulativeResourceSize, overriding UObject::GetResourceSizeEx.

Caveats & Gotchas

• Used by memory profiling tools (e.g. the Resource Size viewer, Size Map) — not something gameplay code calls directly.
• Only accounts for the blend space asset's own data; referenced animation sequences report their own sizes separately.
