So if in your new scene the particle ID is not the same ( for a =
mysterious reason in your case ) the instanced objects can't be the =
same.
I've got the feeling that there is a bug when you export a model with =
some clouds. sometime it breaks the ptypes, sometime not.=20
The best thing is to stay away from this particle system !

Hello,
I'd like to know what's the particle type ID doing.
I have this problem. I created a bunch of particle clouds, each having
a ptype. Those ptype all use instancing.
Particle clouds, instance groups and instantiated geometry are all=20
under a model. When I open the scene, no problem. When I export a
model and re-import it, everything is still there, except that
particle clouds are using the wrong instances. The ptypes are
connected to the right clouds, the groups are referenced by the same=20
ptypes, but yet particles are interchanged.
The only difference I could find was the ptype ID has changed (what
was 6 is now 0, for example). Can this be an explanation?
Thanks
Bernard
