From my experience so far, the LOD popping is not bad in the demos. They seem to have the closer LODs fade in while the farther LODs fade out, this helps. As far as mobile goes they are certainly pushing the client/server model. So I believe a thin client on mobile is not out of the question. Running in Unity has been a pretty bad experience though. The Demo world they provide for unity runs fine, but when I create a world and run it I get some nasty hiccups (which I think is unity choking on all the allocs/deallocs). I have gotten the “bundles” from Voxel Studio loading into UE4 and UE4 seems to do a much better job. I need to work on loading the texture related shtuff.
