Arnold and yeti problem


Hello everybody ! I have a problem with arnold which doesn’t render my yeti fur. I see the fur in my viewport but Arnold only render my geo. I have maya 2022, Yeti 4.0.1 and Arnold mtoa 4.2.4. Maybe it’s just a problem of version which are not compatible or my maya .env. But I don’t find answer in internet so if you have an idea i’ll take it !
Thanks !
