This patterned spiral seashell was produced using photogrammetry of a real shell.

Included with this purchase:

• 5 LOD stages with seperate obj, fbx and stl files
• A blender file containing all LOD stages
• 4096x4096 and 1024x1024 texture + normal maps(tangent space, object space, world space) + ambient occlusion map
• Three unity packages (HQ, Medium, Small) preconfigured with working LODs, simply import then drag and drop the prefab into your scene

Additional Info:

Preview images were rendered with blender renderer.The LOD stages in the blender file are on layers 2-6, and can be viewed by pressing the corresponding number in the 3d view.

All 5 LOD stages share the same UV layout, therefore only needing to load one set of textures into memory at runtime. As a tradeoff however, some texture deterioration occurs on the low poly LOD stages. To mitigate this, uv seams have carefully been chosen to hide the effect (see preview images).

LOD Stages

• LOD0 : 29,923 faces
• LOD1 : 15,370 faces
• LOD2 : 5,072 faces
• LOD3 : 2,536 faces
• LOD4 : 252 faces

The three unity packages are self contained and have LOD configured out of the box (LOD camera distance can easily be tweaked if needed). Versions:

• HQ: LOD0-LOD4 is used with 4096x4096 texture+Normal map+Ambient oclusion map for maximum quality leading to a 42.2 MB package size.
• Medium: LOD0-LOD4 is used with 1024x1024 texture/normal/ambient occlusion maps instead leading to a 6.4 MB package size.
• Small: LOD1-LOD4 is used with 512x512 texture/normal/ambient occlusion maps leading to a 2.2 MB package size.
