Caves and crystals for Unreal Engine

Trees, foliage and rocks for Unreal Engine 5 that work with the Foliage tool from the first import. This group covers underground props for game levels: crystal clusters such as amethyst, quartz, emeralds, rubies and ice crystals, plus a magic crystal, a geode, stalagmites and stalactites. It also includes ore deposits for iron, copper, gold, silver, coal and mithril, and glowing mushrooms that light dark passages. Each model ships with LOD0 to LOD3, collision and a pivot at the base, so it can be placed on cave floors and ceilings without extra setup. Every new seed gives a different crystal arrangement or rock shape, which helps avoid repetition. The models export as GLB, FBX and OBJ for Unity, Unreal Engine, Godot and Bevy. 17 game-ready models in this selection. Every model has LOD0–LOD3, collision and a pivot at the base, and each new seed gives a new variation of the same species.

Using it in Unreal Engine

Unreal Engine 5 imports FBX, OBJ and glTF/GLB (through the Interchange framework).

LODs: enable Import Mesh LODs for an FBX that contains LOD meshes, or add LOD1–LOD3 later in the Static Mesh Editor via LOD Import.
Custom collision: FBX meshes named UCX_<MeshName> are imported as convex collision.
Leaf materials: Blend Mode Masked, Two Sided, and the Two Sided Foliage shading model for light passing through leaves.
Place trees with Foliage Mode or the PCG framework; foliage is rendered as instanced static meshes.
Nanite supports masked materials since UE 5.1. Keep the classic LODs for mobile and other non-Nanite targets.
