Museum Block
The terrain sits on a pedestal. Like a geological specimen in a glass case.
What It Is
The museum block is a solid rectangular base beneath the terrain. Think of it as a display pedestal in a natural history museum — the terrain is the specimen, the block is the stand.
It extends from Y=0 (the terrain floor) downward to a configurable depth. The top surface is flush with the terrain's base elevation. The sides are smooth, dark-colored walls that frame the terrain like a cross-section of earth.
Why It Matters
Without the museum block, you'd see the underside of the terrain mesh — a jagged mess of triangles dangling in space. The block gives the terrain a finished, contained appearance. It's the difference between a raw mesh dump and a presentation-ready asset.
The block also defines the height floor. All terrain operations (generation, erosion, sculpting) clamp at Y=0 to prevent geometry from punching through the base. The museum block is the visual and logical boundary of the terrain volume.

Museum Block + Water
When the water system is enabled, the glass aquarium walls sit inside the museum block. The water's glass box is inset slightly from the block walls to prevent z-fighting. The steel rim wraps just outside the block at the waterline, framing the entire assembly.
The result is a layered presentation: dark stone base, glass water block, reflective water surface, steel reinforcement rim, and the terrain rising out of it all. Like a geological diorama in an aquarium.
