{
var transform = transformMat.transform;
var values = m.Values;
var mat = new Matrix4(
(float)values[0], (float)values[1], (float)values[2], (float)values[3],

transformMat.matrix *= mat;
var translation = mat.ExtractTranslation();
transform.Translation += translation;
if (translation != Vector3.Zero)
transform.Flags |= (int)Transform.TransformFlags.HasTranslation;
var rotation = mat.ExtractRotation();
