Rotate pivot to Targeted Obj
How would I create this same script but without the hassle of using the point object and just modifying the actual objects pivot?
I'm trying to rotate a pivot to look in the direction of a target with an axis constraint.
To test just create a bunch of boxes on different position in 3d space and then create a sphere at 0,0,0 using that as the target.
targetObj = $Sphere001 sel = selection as array for obj in sel do ( --pivotLookAt obj $Sphere001 local dummyPt = point() dist = obj.pos - targetObj.pos dist = normalize dist upVec = [0,0,1] dp = dot dist upVec t = acos dp c = cross upVec dist c = normalize c dummyPt.transform = obj.transform dummyPt.dir = c dummyPt.pos = obj.center in coordsys local rotate dummyPt (eulerangles -90 0 0) in coordsys local rotate dummyPt (eulerangles 0 0 -90) worldAlignPivot obj theRot = dummyPt.rotation in coordsys local obj.rotation *= theRot obj.objectoffsetrot*= theRot obj.objectoffsetpos*= theRot delete dummyPt )

hey grant, have you tried the code i suplied?
with it you just gotta make sure to set yAxis to the local y of the object to rotate
local yAxis = [0,1,0]*$Teapot007.transform.rotationPart
to wrap it in a method:

Thoughts on what I'm doing wrong?

yAxis should of course be the teaPots's local y vector

The attached image just clarifies what I'm after.
I just have a selection of objects who's pivots I want to point in the direction of a "targeted object"
It's just a one time deal. The user runs the script and it just changes the pivots rotation accordingly.
It would rotate them in a way that points the Y towards the target object while maintaining the Z axis pointing directly up, perpendicular to the ground.

do you need it in
do you need it in realtime?
if not the simplest way is to rotate the object.tm by (anle*axis) and then set the verts to their old coords ;)

assigning?
I'm not sure how you are assigning this to the objects pivot?

correct, if the pivot is
correct, if the pivot is currently pointing up ;)
