When creating rotational keys in the keyframer, how do I compound angles using the vectors you ask for? If I want to rotate an object 15 degrees in the Z axis, all I have to do is to set the angle to 15 and the vectors to 0,0,1. What formula is expected to be used when I want to compound two or three axis? I could not reverse engineer what 3D Studio does when I rotate the object by hand and go check the keys. An example I run over and over: 105 deg Y rot. 105 deg Y and 10 deg X X 0 -0.25386 Y 0 -0.19479 Z 1 9.94742 Ang 105 107.9669 And please, pretty please, don't give me the "sqrt(x^2+y^2+z^2)" smart answer. That's pretty obvious. I want to know how did you (3D Studio) derive those components and came up with that resulting angle. This is urgent. I sent this morning a KXP that needs this. I couldn't figure this one out but decided to send it in any way. What I am doing for now is creating a separate key for each axis I need rotated. Let me just say that several tons of high tech machinery crashed and this KXP will be used to recreate the incident.
