nope. doesnt work. been that way since distributed irradiance map 1st came out. we have been hopping that they find a solution to this but for now sorry dude. doesnt work
i guess the next closest thing would be to distribute the first frame to get a nice detailed starting map quick, then load locally on each server, and add to that map, each one doing a different chunk of anim, before merging the 6 maps at the end… hmmm… not the simplest..
