Polaris Mini is a lightweight tool to convert your existing terrains to optimized mesh prefab which will greatly improve your game performance, especially on low end platforms.
 
KEY FEATURES
Export terrain as mesh prefab: All components needed (Renderer, Material, Collider, LOD, etc) are already setup, just drag and drop the prefab to the scene.
Adaptive mesh: The mesh can adapt to the height map complexity, less polygon at plain areas, more polygon at rough areas. A huge save to vertex memory.
Mesh splitting: The terrain will be cut into several smaller chunks to get around the 65k vertex limit.
Up to 4 LODs: Seamless transition between LOD, no gap!
XZ displacement: Offset the vertex on XZ plane to break the uniform look.
Holes support: Cut the polygons away for the hole, add more polygon to emphasize the hole edge. No need to setup triggers for hole interaction.
Hard/smooth normals: Cover both low poly & stylized shading style.
Merge UV: Collapse the polygon's UV for sharp color.
2 material variants: Use splat textures (4 layers without normal maps) or use albedo/metallic map.
Runtime conversion: Convert terrain at runtime using the TerrainToMeshConverter class.
*Tree & detail export is NOT supported at the moment.
