View Full Version : How can I save motion paths when they are parented?

I am trying to make a simple spiral path for a rail extrude operation and I found the easiest way to make it is to take a pivot null, parent null2 to it, and translate null2 in the x axis as it turns. It makes a perfect spiral.

Now I want to take this path into modeler for a rail extrude but of course the path seen by layout on null2 is simply an x translation not a spiral.

Is there a way to bake the absolute motion of null2 and save it?

Thanks for any help.

Its been a long time since I've done any lightwave work so I'm pretty rusty at this stuff :D

I'm using lightwave 9.6..

Try MF Motion Baker to bake the motion to keyframes:

This lscript will take the motion of null2 and place keyframes on every frame from the start of the x translation to the finish but it doesn't include the motion of the parent's rotation. I need something that will combine the two motions together.

Thanks

Ah ha!

This plugin will achieve what I need. To make it work I had to add a 3rd null (follower) which has a motion modifier called follower. Then bake follower's motion and save it's .mot out.

The comments on the site led me to the solution.

Thanks again!:D

This doesn't sound easier than using LATHE and adjusting the offset in the numeric panel.

I needed more control

Guess I have different definition of "simple".
