Wny it happend???

it seems to switch back whenever you move the viewer, but it is impossible to render correctly.
I would say you make this in 2.49 instead, the 2.5 particles seem very unstable.
other than that i cant help you, sorry.

Thank you all for reply.
I’m sad, very sad.((
Evil eat my heard, why developers don’t work on this general thing???

I found the way to go - rotate feather object and children (particle feathers) will rotate to… but this is not exelent way…

Hellow.
This is a realy the bug. How i can to notify developers about?

ps: i make particles with hairs.
