We are working in the 2.8 code base already but there is a lot still to do since physics will not be updated in 2.8 until the second wave of 2.8 development later in 2019. Also it will take me a while to update the documentation.
So like mcbeth’s investment in 2.79x Fracture Modifier is still a good way to go. FM 2.79x will be around for a couple more years at least since we have such a big user base.
I’ve given more details in earlier posts if you scroll back. We’ll keep you updated.
Until then Fracture ON with 2.79x!
