Hi Neil, << The basic approach has been to align a dummy object within the 3DS scene, and then query the position and rotation of this object within the script. >> You'll find my version of this puzzle on the "Inside 3ds4" CD-Rom. '———————————————————– ' CAMTRACK.K3D ' Keeping Objects Perpendicular to a Camera's Position ' An "Inside 3D Studio" utility ' By: Jonas Ruikis ' ' CAMTRACK rotates a selection of objects about their pivot point (of course) ' so their first face is prependicular to a selected Camera's position. ' Axes may be locked for the objects. ' Either the camera and/or the objects may be in motion. ' Respects the current Time Segment ' ' ================================================================ Track this script down and enjoy it.. A few tips.. I had to compute the dot product and the cross product in order to find the axis and rotation. Also, don't try to create a rotation key on frame 0. jonas[adesk]
