View Full Version : Rotating Spline control objects

09-23-2013, 04:48 PM
I'm testing out Spline Control with some letter objects, but they are facing the wrong way. Anyone know how to rotate them? I've tried changing the rotation controllers to Key Frame in Motion Options, but that seems to just screw things up.

Maybe just change the orientation of the objects in Modeler? I'm guessing +Z is assumed to be pointing down the curve? (but don't know for sure -- haven't played with it yet...)

Perhaps not understanding the situation but the B and S are both facing the same direction. Are you wanting to flip them all? Does flipping the start of the curve change them?

I'd like the spline to go through the sides, not the front / back. So in the example pic the letters would all face toward us.

Like tburbage said, I think the Z axis is aligned w/the spline. IOW, rotate in LWM.

try the scene editor for rotation of 1st letter, then parent each letter to the one before, co-ords system = parent, parent in place = off.
I'll check all this - it's a while since I did the tutorial.
I don't think you should rotate in modeler, but I'll get back.

this tutorial by Jen H.
It's in issue_02 summer edition of the lightwave magazine.

Yeah the Escalator one is also in Jen's Siggraph video (http://www.ustream.tv/recorded/36317873). While helpful, it's not what I need as that removes all of the rotation from the objects. I want them to rotate along the spline, just facing 90 degrees to one way or the other. I think I need to rotate them in Modeler, or at least make a morph that rotates them. BTW That video is also good as drinking game, every time Jen says "yup" you take a drink. :p

So rotating them as a morph in Modeler fixed it. Didn't have to be a morph I just liked the idea of easily getting it back into position.

Morphing also gives you more animation options: if you did a wiggle on the morph envelope, it might be interesting (or abysmal).

this might help, RH has just added 14 to YouTube.
my view remains to do the basic 'da Vinci' model in modeler, move to Layout and do all manipulation there.
What if, in a scene, there are many splines all with a different rotation using the one object - why would you do rotation in modeler.
Nice about the morph, but no cigar. :D
