UBlendSpace::bAllowMeshSpaceBlending

property Engine Since 5.1

#include "Animation/BlendSpace.h"

Access: public Specifiers: UPROPERTYEditAnywhere

Description

Enables mesh-space blending when per-bone sample smoothing overrides are in use, so different parts of the skeleton can reach their target pose at different speeds — for example, letting the head turn toward an aim target faster than the body.

Caveats & Gotchas

• Mesh-space blending is significantly more expensive than normal local-space blending, so only enable it where the visual benefit justifies the cost.
• Blend spaces with additive or mesh-space samples always blend in mesh space regardless of this setting; enabling it alongside blend space graphs that already produce additive/mesh-space output can cause undesired results.
• Has no effect unless per-bone sample smoothing overrides are configured on the blend space.

Signature

bool bAllowMeshSpaceBlending = false

Example

Enabling per-bone mesh space blending C++

// Typically set in the Blend Space editor's Details panel, under Sample Smoothing.
// Equivalent C++ (e.g. when constructing a blend space asset in an editor tool):
BlendSpaceAsset->bAllowMeshSpaceBlending = true;
