void OutputTangentToWorld(half4 vertexTangent, half3 vertexNormal, out half3 tangentWS, out half3 binormalWS, out half3 normalWS)

// mikkts space compliant. only normalize when extracting normal at frag.

tangentWS = TransformObjectToWorldDir(vertexTangent.xyz);
binormalWS = cross(normalWS, tangentWS) * sign;
