Caustics pre-calc ?

[Fat Tony]

Is there a way how to pre render caustics similar way as LC for example ? Am trying to render animation and didnt find a work around it. Every frame is building caustics from scratch, which to be honest make sense just was curious if there is a way how to do it more efficiently for anim.
thanks

What's the animation type, fly-through or with animated objects?
If the caustics are static you may bake them(Save to file and then set Mode to From file) to a single map and use that map throughout entire animation, if they are animated however a calculation of each frame will be necessary.

Yes it is animated, i thought that is the case, just wanted to make sure i am not missing on anything.
Thanks
