Dear Graham,
I don't understand why the team changed the cliffs in The Sims 4. The visual seems a little polluted.
I'm creator of worlds to The Sims 3 and I loved modeling mountains, cliffs and rocks like the reliefs of Sunset Valley, Hidden Springs and Monte Vista. I think these were more naturals.
These rocks/cliffs look like big toys lost in the neighborhood. I don't understand very well about it but I also think all these are more elements being renderized. I can't see positive aspects, because they aren't more beautiful than reliefs in The Sims 3.
I will be satisfied if the team decides to change.
Good week.
