View Full Version : Predefined Path to Spline Control?

11-15-2013, 07:14 AM
This would be perfect for Spline Control but I'm left a little unsure the best way to set it up!

I've got an animated Camera move that I'm happy with in terms of the path it's taking but I need to change its speed at various positions - a massive pain before Spline Control!

Is there a way to replace an item's already mapped out path with Spline Control - some kind of Path to Spline Control button?

so soon...?

knots = 10;
frameStart = 0;
frameStop = 100;
frameRange = frameStop - frameStart;
knotIncrement = frameRange/knots;

motionItem = Scene().firstSelect();
currentFrame = frameStart;
now = Scene().currenttime;
motItemPos = motionItem.param(WPOSITION, now);
motItemRot = motionItem.param(ROTATION, now);
currentFrame += knotIncrement;

Obviously, set the numbers yourself for how many knots, and the frame range you want to cover, then select the item in question and run it.

This is so useful, it should really ship with LW! Had to adjust a few rotations but really great stuff, RH. Lovely! For future ref, is it simple to hook a UI to these things?

I updated it to add the moving items name to the spline null set name, so doing it for multiple items in a scene wont cause naming errors, or make you have to do renaming by hand.

Tbh... I do see a potential usefullness for this as a general thing, I might add a UI and add it to my rigTools.

Great news :D. Already finding it useful for a few mograph situations...

Hi RH. Just a quickie - is it easy to adapt this script to keys-to-spline? So taking a selected path and adding nulls/Spine Control at the keyframes position on the selected path (rather than at intervals, as the previous one does).
