The quality of the landscape and materials is really down to how you configure it, I do plan on including some nice materials but I am a programmer 
So if any artists want to contribute, I would be very happy to accept! This is with the patches turned up to 128x128 and the unit size down to 200 and some starter content materials. As you can see the mesh and collision update with that size patch is a problem.
I am regularly chatting with Simon () on Slack about our projects. Thanks on the link for the world origin stuff…I am not actually resetting origin at the moment, need to get around to doing that.
I’ve been talking with Koderz on slack about enhancements to the ProceduralMeshComponents, particularly as regards smarter threading on the collision updates which should enable these higher res meshes to load in nice and smoothly.
