Sudden crashing when "flow path object"

[jclau...@gmail.com]

hey all,

i've been working on a scene for a few days that is basically a bunch of geometry "flowing path object" using motion paths

its worked for a few days just fine with dozens of objects...suddenly today Maya crashes whenever i go to "flow path object"

1) restarted maya
2) restarted computer
3) trashed prefs
4) tried an empty scene with same technique (it works)
5) tried to import elements from old scene (it crashes)

any thoughts short of losing a few days of work?

Maya 2017 on Mac El Cap

thanks,

john

I had the same problem a few years back. Maya 2013... or maybe 2010. But i found the source of my problem. In my case, the curve was referenced. And when you attach motion path to the curve, maya will add locator shape object under the curve transform. Since the curve was referenced, i think it caused maya to crash whenever it tried to add the locator shapes during scene load. My solution was simply to delete the locator shapes and not using keyframe on the parameterU on that motion path. Instead  I created an attribute and do the keyframe on that attribute. Then connect that attribute to the parameterU.

For flow path object, i suggest you group the objects under one transform and apply motion path on that group. Unless you want different motion on different object, maybe do it on duplicated curves.

That's all I can think of for now.

thank you,

i think it may be that i erroneously "scaled" the "lattice", and that made it blow up.....crazy
