Fantastic @danmelt! So far you’re the first mountain I’ve seen sculpted. Kudos for delving into retopo as well. Way ahead of schedule 👏
I think the mountains will be *very* optimizable for the final polycount. Maybe as low as 1000 triangles. The vast majority of their detail will be in normal maps / textures. The expectation is that mountains only need to look good from the foreground zone (immediate area surrounding the house). Still given their size, I think they should be 3D instead of flat cards.
Don’t worry about optimal geometry yet though. Week 2 I’d like to see you focus on sculpted detail. There’s room for a lot of mountainous detail in sculpt form to be baked down.
