UBlendSpace::InitializeFilter
#include "Animation/BlendSpace.h"
Access: public
Specifiers: const
Description
Sets up runtime filtering state for smoothing blend input, using this blend space's InterpolationParam settings.
Caveats & Gotchas
- • Must be called once before the filter is used with FilterInput/UpdateFilterParams — using an uninitialized FBlendFilter produces garbage smoothing results.
- • Called internally by the anim graph's blend space node; you only need this when driving a blend space manually outside the normal asset player pipeline.
