Soka Asset Prep is a guided Unity Editor extension for preparing imported 3D models for use in game projects while preserving the original source files. Analyze up to eight FBX LOD models, identify common setup problems, configure materials and emission, visually build compound primitive colliders, and generate an organized prefab with a validated LODGroup. The workflow presents its findings before making changes. You decide which corrections to apply, and generated materials and prefabs are saved as separate assets rather than overwriting the original FBX or GLB files.The included rock, house, and flower demonstration models were generated locally using ShapeCast. Soka Game Design selected the outputs, prepared their LOD and material data, configured their colliders, and validated the resulting prefabs using Soka Asset Prep. The Unity Editor extension, workflow, documentation, tutorial, and source code were authored and assembled by Soka Game Design.KEY FEATURES• Analyze 1–8 FBX LOD levels• Find matching LOD files using their filenames• Review scale, bounds, renderer, material, and naming findings• Keep imported materials, share one material, or assign materials per LOD• Extract embedded GLB base-color, metallic/roughness, and emission textures• Create adjustable emission masks and HDR emission settings• Preview Box, Capsule, and Sphere colliders directly on the model• Add, duplicate, remove, move, resize, and configure multiple colliders• Generate an organized prefab with an LODGroup and approved collider layout• Validate the generated prefab and review its results• Save reusable asset-preparation presets• Follow an included in-Editor tutorial and offline user guideINCLUDED DEMONSTRATION CONTENTThe package includes rock, house, and flower demonstration assets that allow users to learn and test the complete workflow. These examples demonstrate different asset types rather than limiting the tool to a particular artistic style or game genre.DESIGNED FOR• Solo game developers• Indie studios• 3D artists importing assets into Unity• Developers preparing purchased or generated models• Teams that need a repeatable prefab-preparation workflowTECHNICAL INFORMATION• Unity Editor extension• Tested with Unity 6.3 LTS on Windows• Built-in Render Pipeline tested• FBX input with optional embedded GLB material extraction• No account, subscription, telemetry, external API, or network connection required• Original source models remain unchangedLIMITATIONSSoka Asset Prep does not create new mesh geometry, generate new LOD models, repair UVs, or paint missing textures. Complex or concave models may require additional manual collider refinement. Scene Bloom and post-processing must be configured separately when using emission.
