real time trajectory spline

[Anonymous]

Hello. Is there any way to have spline of a trajectory as an instance copy (I mean when trajectory of an object changed the spline change too.)(In real time no with extracting line and importing it.)

Hello @Anonymous and welcome to the community,

I don't believe so, but you might be able to find a script that does this sort of thing.  Maybe this could help?

If you assign Path constrain controller to object you'll have same trajectory as spline path.

Transforming points on spline path must be reflected on trajectory/motion path.

Can't do the same on trajectory because there's no position keys.

But maybe you looking for a way to change trajectory in viewport?

Funny!

What's new in 3ds Max 2018 - beside changing names😁

Hello Diffus3d .Thanks for this script it is very useful but not in my case . I dont want to edit trajectory spline I want to just have a same line from trajectory and it let me to add some modifiers on the line.

or at all for my goal this is a main question that, is there any way to with changing the position of some thing , automatically a spline going to generate and follow objects path.

Hello @Anonymous ,

Apologies for the late reply, somehow my autodesk messages ended up in SPAM.  Fixed now.  

My best suggestion would be to post in the scripting forum to see if someone can help you make a script to do what you are looking for.

I posted it in script spot and Autodesk_3dsmax_programming , but any body didnt write a script for it.

What should I do?

I'm not sure what to tell you @Anonymous , typically the workflow is to animate an object to a spline rather than vice versa.  Are you just trying to leave trails behind an object?    What's the purpose of the spline?

I want to use the trajectory spline for having a update able line that carry sweep modifier and has trail texture on it. and before rendering I will use projection modifier on my land and the line will project its texture on my land.
Any way????

I don't know of a way without scripting @Anonymous, sorry.
