Pflow Arnold Shape node...everything grayed out

[Anonymous]

Hey all, to begin, I'm using MaxtoA.

So I need some instances with offset animation as particles.

I couldn't seem to render anything in Arnold (kept hanging on 'initializing render') until I changed my shape node to 'Arnold Shape', and then it render fine.

However, in Arnold Shape, all of the controls for choosing an animated shape and offsetting it, etc, are all present, but grayed out. So, I can't have an animated shape as a particle, rendering Arnold? What am I doing wrong?

thanks for your time.
