Crystal outcrops

A low-poly alien crystal outcrop: a faceted deep-purple boulder mound with clusters of glowing teal and magenta hexagonal crystals, plus small ground shards and pebbles around its base.

How it was made

The brief given to 1DesignTool's “3D object” template:

Crystal outcrops for the Alien Jungle kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. This is one part of the Alien Jungle kit (Low-poly style, flat-lowpoly direction): A glowing forest on another world. Use ONLY the kit palette, by name: teal #2d8686, magenta #d02597, bioluminescent green #3a883a, deep purple #432055, teal dark #1a4d4d, magenta dark #8f1968, teal light #46b9b9, magenta light #de63b5, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `glowColour` (0–1, default 0.5) for the kit's "Glow colour" setting wherever it makes sense on this part, and keep that id.

Note: Static environment prop, 1.94 m tall with a 2.72 x 2.29 m footprint at default params (the main spire is about 1.2 m of crystal rising from a 0.7 m boulder mound). Origin is at bottom centre, it rests exactly on y=0 and the front faces +Z. Part ids use the root 'crystaloutcrops' rather than the hyphenated slug because the kit's part-id checker only allows [a-z0-9] in the first segment. Every material is named exactly its Alien Jungle palette colour; crystal materials carry a low palette-coloured emissive so they glow in engines that read glTF emissive. glowColour (0-1) changes the GEOMETRY'S MATERIAL ASSIGNMENT, not a blended tint: each crystal cluster and ground shard switches from teal to magenta once the knob passes its own threshold, so 0 is all teal, 1 is all magenta and 0.5 splits the glow roughly half and half — colours always stay exact palette values. spireHeight scales every crystal (overall height ranges about 1.5-2.5 m), crystalCount sets crystals per cluster, lean fans the clusters outward; the model stays grounded and attached across all ranges. Facets are baked into the geometry (non-indexed, flat normals) so the low-poly look survives in any importer. The exporter clones materials per mesh, so the GLB lists 17 material entries using these 7 palette names; glb-lint's material-count, duplicate-material, non-indexed and sibling-overlap warnings are expected consequences of that, of the flat-shaded geometry and of crystals intentionally embedded in the rock. The viewer's ground disc and light rig are staging only and not in the GLB, which has no animation clips. Exported model: 1190 triangles.
