However, you should do it carefully, especially when modifying scaling, since Soya store the scale factor in additional values in the matrix (This is why Soya matrixes have 19 values ; however you can set the matrix to a 16-value list, and soya will kept the 3 last values of the current matrix). Pablo, you can either set the matrix attribute (if you have the right matrix values), or perform first a look_at (e.g. on the X axis), and then perform a rotation in order to set the Y and Z axis as needed, e.g. if you want Z to point to idealZ, perform a rotation around the cross product of currentZ and idealZ, with an angle being the angle between currentZ and idealZ. This is what I usually do when I am in a situation like you. Jiba
