Cave Voxel

CaveDeco — Low-Poly Cave Decoration Pack

CaveDeco is a collection of 36 unique low-poly 3D models supplied as 36 prefabs for decorating caves and stylized environments. The pack includes 10 crystal models, 10 vegetation and mushroom models, and 16 rock, ground, sand, gravel and brick props. Crystals feature an animated shimmering surface effect.

Included assets

- 36 unique mesh assets and 36 corresponding prefabs. Prefabs are not counted as additional unique models.

- 9 materials: 8 materials using volumetric textures and 1 untextured material.

- 9 unique RGBA PNG textures: 8 base-color textures and 1 crystal shimmer texture.

- Shader versions for the Built-in Render Pipeline, URP and HDRP.

- 1 demo scene, 2 C# scripts (FreeCam and Help), and a PDF readme.

Textures and materials

All 9 surface texture source images are 32 × 1,024 pixels, RGBA PNG. Each image contains 32 stacked 32 × 32 slices and is configured for import as a 32 × 32 × 32 Texture3D. The custom shaders sample these textures in world space.

The crystal shimmer map contributes animated color to the surface albedo; it is not a separate emission map. No separate normal, metallic, roughness/smoothness, ambient-occlusion or displacement maps are included for the props. Metallic and smoothness are controlled through material parameters. Textures are shared between models.

Per-asset technical details

Names below match the prefab paths relative to Prefabs/. Texture filenames are relative to Textures3D/. Every listed texture uses the source and imported dimensions specified above. All maps are base-color maps except crystalBlicks.png, which is the additional shimmer map. “Untextured” indicates an additional material without texture maps.

Render pipeline setup

Materials in this package are currently assigned to Built-in Render Pipeline shaders. Separate URP and HDRP shader files are included; using those pipelines requires assigning the appropriate shaders and configuring the materials for the target pipeline. The package uses Texture3D sampling and requires a graphics API/platform supporting 3D textures.
