Mesh.bindposes

var bindposes: Matrix4x4[];
Matrix4x4[] bindposes;
bindposes as Matrix4x4[]

Description

The bind poses. The bind pose at each index refers to the bone with the same index.

The bind pose is the inverse of inverse transformation matrix of the bone, when the bone is in the bind pose.
