Convert Unity terrains into optimized mesh assets with baked textures, LOD groups and FBX export. Ideal for the creation of e. g. backdrop mesh like mountains for vast terrain immersion.The asset is designed to work in all render pipelines.OverviewConvert Unity terrains into optimized mesh assets with baked textures, LOD groups, and FBX export. Ideal for the creation of e. g. backdrop environments like mountains.Terrain Converter takes your Unity Terrain and produces a clean, game-ready mesh with blended textures, configurable simplification, and automatic LOD generation. Everything runs inside the editor with GPU-accelerated texture blending and built-in mesh simplification.The result is a standard mesh prefab with materials, ready to drop into your scene or export as FBX for use in other tools.The main intent of the creation of this asset was that I wanted to create backdrop mountains using MicroVerse in order to create the immersion of a vast environment for the player.This asset is part of the Genesis for MicroVerse suite. However, since it works general purpose as well this asset is being released as a dedicated asset.Upgrade PathEveryone who owns any of these assets will get this asset at a discount:Ultimate StampIT! CollectionGenesis for MicroVerseRequirementsThe following is required for this asset:Unity 6.0 or laterUnity 6.3+ for MeshLOD simplification (otherwise Fast QEM and QEM are available)Unity FBX export package: com.unity.formats.fbx packageUnity terrain shaderLinear color spaceFeaturesMesh GenerationGenerate meshes from your terrain heightmap at configurable grid resolutions from 32×32 up to 1024×1024. The converter samples the heightmap directly and produces a clean, UV-mapped mesh with proper normals and tangents.Mesh SimplificationBuilt-in simplification methods to reduce polygon count:Fast QEM (Quadric Error Metrics): Forstmann simplification with boundary and UV seam preservation. Adjustable keep percentage (1–100%) and three quality presets (Low, Medium, High)QEM (Quadric Error Metrics): Garland-Heckbert simplification with boundary and UV seam preservation. Adjustable keep percentage (1–100%) and three quality presets (Low, Medium, High)MeshLOD (Unity 6.3+): Uses Unity's built-in MeshLodUtility to generate LOD levels directly in the mesh index buffer. Optionally extract a specific LOD level as a standalone flat mesh.GPU Texture BlendingTerrain layer textures are blended on the GPU using a compute shader. The system reads your terrain's splatmaps and layer settings (tiling, offset, diffuse remap, mask remap, normal scale, metallic, smoothness) and produces ready-to-use textures:Albedo (BaseColor) - blended diffuse with alphaNormal Map - blended and decoded tangent-space normalsMask Map (MOADS) - metallic, occlusion, detail, smoothness packedSupports output resolutions from 512×512 to 8192×8192 with optional supersampling (2×, 4×, 8×).LOD Group GenerationAutomatically generates a complete LODGroup with configurable level count (2–5), per-levelscreen transition thresholds, and per-level simplification ratios. Each LOD level gets its ownsimplified mesh asset. Works with Fast QEM, QEM and MeshLOD simplification.FBX ExportOne-click export to FBX format via Unity's FBX Exporter package. The exported FBX isautomatically configured with correct import settings (normals, tangents, no animation,readable mesh).Scene PlacementPlace the converted mesh at the same position as the source terrain, or offset it to any side (left, right, front, behind) for easy comparison.Batch ProcessingConvert a list of terrains individually or combine them all into a single mesh.What this is notThis asset is not designed to convert multi-tile terrain into individual meshes and keep the vertices aligned across bounds, especially not with vertex reduction active. The conversion is performed on the heightmap and textures, terrain specific features like trees and details aren't transitioned.Complete editor tool with full source codeGPU compute shader for texture blendingFast QEM mesh simplifierQEM mesh simplifierMeshLOD bridge for Unity 6.3+LOD group generatorFBX export helperIndividual or combined mesh creation
