c4d to unity : Alternative to PLA?

Hello,

Is there someone who can help me to find a solution. I have got an animation in c4d where I translate a lot of vertices. I want to export my animation in unity(FBX) with the PLA option enabled but Unit doesn't support the pla animation. i've been searching a lot and the only answer I found was the megafiers plugin in the asset store. In the other case, the answers are that unity doesn't support Point Level Animation... Is there an other solution less expensive(the plugin cost 150$ :O )? Thank you
