Re: *.obj sequence import?

[Juan Brockhaus <juanb(at)the-mill.com>]

Hi,

this is a script I've written which imports an obj sequence as 
shape-animation.

Don't have the time to rewrite at the moment, but it's pretty straight 
forward to make it work to set visibility keys.

change .lalala to .js

Hope that helps,

Cheers,

Juan
