Shake 3.5 Rotoshapes Lin--> Hermite

[user_deleted]

Hello,

In my Company I work with Shake 3.5. For a Fluid Animation Script I use some animated Rothoshapes as Base. All works fine, but the animation of the Points in my Rotoshape are moving Linear and this makes it not really realistic. Can i Change the Keframe Imterpolation of my roto from Linear to hermite ? And How ?

I know in Shake 4 it is possible, but in shake 3.5 ... hm ???

plz Help

Thanks a lot
