I'm interested in this also. I've noticed some of the sample terrains are up to 11,000 x 11,000 (x & y) units. Don't forget if you resize the initial terrain and then apply a material extra nodes are added. I'm trying to fathom out the functions and nodes and looking at examples now, but it's a long hard slog working out what each one does, then how they work in combination and then finally being able to make Vue reproduce the results you want. Thankfully the V5i manual is much better than previous versions and details each function in more detail than before. I'm not saying that as a bad thing, but this is the hardest learning curve I've had with Vue so far :)
