UE4 Tesselation multiplier from Cascade

Hey guys,

I’ve been thinking, can I control tesselation multiplier from Cascade? or animate it from Blueprint? Looks like dynamic parameters and particle color can’t be used for the tesselation multiplier.
I have a suspicion that this is because if I will recompute geometry every frame my PC will blow up. But I’m a newbie and I could be wrong. So I need sage advice from you guys. =)
