crater terrain 3d model

ORIALIS greybox terrain, ~1400x1400 m, single landmass, human scale 1.8 m. BASIN (center): shallow rocky bowl, floor z=0, ~700 m wide, rimmed by ridges z=+30..60. Crash Site = tilted cylinder lander 25 m, half-buried, at (-180,-90). Seedcore Dome = cracked hemisphere r=18, half-sunk, at (140,20). First Base = 30x30 flat pad + 4 crates at (150,-60). Rock spires 5-15 m around the rim. RIFT GLACIER (north, y>+300): ice plateau rising z=+60..220, one straight E-W crevasse 15 m wide, 40 m deep. Blue Ice Caves = arch cave mouth 12 m at (-260,+380). Wind Generator Ridge = crest z=+180 at (+300,+320). First Sprout Valley = flat sheltered hollow z=+40 at (+260,+300). Ramp climb Basin->Rift at y=+280. ASHLANDS (south, y<-320): cracked black terrain sloping z=0..-80, jagged fissures. The Vault = 40 m vertical cliff face + recessed circular door r=10 at (-300,-420). Beacon Array = flat-top mesa z=+50 + 4 broken poles 20-30 m at (+320,-430). Vent cones 3-8 m scattered. Outer edge: cliffs droppi
