animated caustics per frame script?

[kimgar]

I read a thread here regarding precalcing caustic files ala IR map prepass mode.
It mentioned the need for a script to save and load photonmaps for caustic animation.

Thread being many years old I was just wondering if this is still the way to do it?

You can use %04d in the caustics map name to save a map for each frame and then respectively load it.
