A comprehensive guide to Unity design asset workflows powered by Antigravity IDE. Covers AI-assisted shader generation, 3D model pipeline automation, texture management, and asset bundle optimization.
Building high-quality games in Unity requires managing complex asset pipelines: importing 3D models, writing custom shaders, optimizing textures, and packaging everything into efficient asset bundles. When done manually, these tasks are time-consuming, error-prone, and create bottlenecks in your development cycle.
Antigravity IDE changes the equation. As Google's AI-powered development environment, Antigravity doesn't just autocomplete code—it understands your entire Unity project structure and can orchestrate complex workflows through intelligent AI agents. This guide walks you through transforming your asset creation pipeline with Antigravity, from shader generation to production-ready asset bundles.
How Antigravity Transforms Your Asset Pipeline
Traditional asset workflows in Unity involve juggling multiple tools and processes. A shader artist writes HLSL, a technical artist optimizes meshes, an engineer builds asset bundles, and everyone waits for integration to happen. Antigravity streamlines this by:
Automating shader creation: Generate HLSL and ShaderLab code tailored to your rendering pipeline
Intelligent model processing: Automatically import, optimize, and generate LOD systems for 3D models
Smart texture management: Pack textures into atlases, optimize resolutions per platform, manage sprite sheets
Seamless CI/CD integration: Build and version asset bundles as part of your automated deployment pipeline
The result is faster iteration, fewer bugs, and more time for artists and designers to focus on creativity rather than technical plumbing.
Configuring Your Unity Project for Antigravity
Setting Up the .antigravity Configuration
For Antigravity to work effectively with your Unity project, you'll define project contexts, capabilities, and agent roles using a .antigravity configuration file at your project root. This tells Antigravity how to understand your codebase structure and constraints.
This configuration enables Antigravity to maintain context across tasks and understand the relationships between your Assets folder, build scripts, and deployment pipelines.
Bridging Unity APIs for IntelliSense
To maximize IntelliSense accuracy when Antigravity generates code, create a type bridge that preloads Unity's standard APIs and custom structures:
// Assets/Plugins/AntigravityUnityBridge.csusing UnityEngine;using UnityEngine.Rendering;/// <summary>/// Type bridge for Antigravity code generation./// Ensures accurate IntelliSense and type checking for AI-generated scripts./// </summary>public static class AntigravityUnityBridge{ public static class ShaderAPI { public static Material CreateMaterialFromProperties( string shaderName, ShaderPropertyInfo[] properties) => null; public static void ApplyMaterialToRenderer( Renderer renderer, Material material) { } } public static class ModelAPI { public static void GenerateLOD( Mesh originalMesh, float[] lodScreenHeights) { } public static void OptimizeMeshForMobile( Mesh mesh, int maxBoneWeights = 4) { } } public static class BundleAPI { public static void BuildAssetBundles( string outputPath, BuildAssetBundleOptions options) { } public static AssetBundleManifest GetManifest( string bundleDirectory) => null; }}public class ShaderPropertyInfo{ public string name; public string type; public float defaultValue; public float minValue; public float maxValue;}
With this bridge in place, Antigravity generates code that's not only syntactically correct but semantically aligned with your project's architecture.

AI-Assisted Shader Generation and Material Management
Generating Production-Grade Shaders
Shaders define the visual quality of your game. Writing custom shaders is time-consuming and error-prone, especially when targeting multiple render pipelines. Antigravity can generate complete shader implementations based on high-level requirements.
Here's how you might prompt Antigravity's shader agent:
/*Generate a physically-based rendering (PBR) shader optimized for mobile platforms.Requirements:- Support albedo, normal, roughness, and metallic textures- Implement Cook-Torrance specular highlights- Include environment reflection using ambient light- Minimize texture samples for mobile performance- Support up to 4 directional lights (URP forward rendering)- Include alpha blending optionTarget: Assets/Shaders/PBRMobile.shaderLanguage: ShaderLab with HLSLOptimization: Mobile (iOS/Android at 60fps on mid-range devices)*/
Output: A complete, mobile-optimized shader ready for production. The generated code handles:
Proper PBR workflow with metallic/roughness textures
Normal mapping with tangent-space calculations
Shadow pass for realistic lighting
Minimal texture samples (4 lookups per pixel)
Managing Material Properties at Runtime
Alongside shader generation, Antigravity creates companion C# scripts to manage material properties dynamically:
// Generated: MaterialController.csusing UnityEngine;[RequireComponent(typeof(Renderer))]public class MaterialController : MonoBehaviour{ [SerializeField] private Material material; [Range(0f, 1f)] public float roughness = 0.5f; [Range(0f, 1f)] public float metallic = 0f; [Range(0f, 1f)] public float ambientIntensity = 0.3f; private static readonly int RoughnessID = Shader.PropertyToID("_Roughness"); private static readonly int MetallicID = Shader.PropertyToID("_Metallic"); private static readonly int AmbientIntensityID = Shader.PropertyToID("_AmbientIntensity"); private void OnValidate() { if (material == null) material = GetComponent<Renderer>().material; UpdateMaterialProperties(); } public void UpdateMaterialProperties() { if (material == null) return; material.SetFloat(RoughnessID, roughness); material.SetFloat(MetallicID, metallic); material.SetFloat(AmbientIntensityID, ambientIntensity); } // Runtime API for dynamic material changes public void SetRoughness(float value) { roughness = Mathf.Clamp01(value); material.SetFloat(RoughnessID, roughness); } public void SetMetallic(float value) { metallic = Mathf.Clamp01(value); material.SetFloat(MetallicID, metallic); }}
Automating 3D Model Import Pipelines
FBX/glTF Import Optimization Scripts
When importing multiple 3D models, maintaining consistency in mesh optimization, bone weight settings, and normal generation is critical. Antigravity generates post-processor scripts that automatically apply these optimizations:
// Generated: ModelImportOptimizer.csusing UnityEditor.AssetImporters;using UnityEngine;public class ModelImportOptimizer : AssetPostprocessor{ void OnPreprocessModel() { ModelImporter importer = assetImporter as ModelImporter; // Compression: reduces file size and load times importer.meshCompression = ModelImporterMeshCompression.High; // For runtime read-only models, disable CPU access importer.isReadable = false; // Automatic mesh optimization importer.optimizeMeshPolygons = true; importer.optimizeMeshVertices = true; // Bone weight constraints for mobile importer.maxBoneWeights = 4; importer.skinWeights = ModelImporterSkinWeights.Max4Bones; // Import normals and tangents for proper lighting importer.importNormals = ModelImporterNormals.Import; importer.importTangents = ModelImporterTangents.ImportNormals; // Animation support importer.importAnimation = true; importer.animationType = ModelImporterAnimationType.Generic; } void OnPostprocessModel(GameObject g) { // Post-import mesh optimization foreach (var meshFilter in g.GetComponentsInChildren<MeshFilter>()) { Mesh mesh = meshFilter.sharedMesh; if (mesh != null) { mesh.RecalculateBounds(); mesh.RecalculateNormals(); } } }}
Automatic LOD (Level of Detail) Generation
LOD systems dramatically improve performance by switching between high and low-poly models based on camera distance. Antigravity generates the complete LOD infrastructure:
// Generated: LODSystemBuilder.csusing UnityEngine;public class LODSystemBuilder : MonoBehaviour{ [SerializeField] private Mesh highPolyMesh; [SerializeField] private float[] lodScreenHeights = { 0.5f, 0.25f, 0.1f }; public void BuildLODGroup() { LODGroup lodGroup = gameObject.AddComponent<LODGroup>(); LOD[] lods = new LOD[lodScreenHeights.Length + 1]; // LOD 0: High-quality (original mesh) lods[0] = CreateLOD(highPolyMesh, 1.0f); // LOD 1+: Progressively simplified for (int i = 0; i < lodScreenHeights.Length; i++) { float reductionRatio = Mathf.Pow(0.5f, i + 1); Mesh simplifiedMesh = SimplifyMesh(highPolyMesh, reductionRatio); lods[i + 1] = new LOD(lodScreenHeights[i], CreateRenderer(simplifiedMesh)); } lodGroup.SetLODs(lods); } private LOD CreateLOD(Mesh mesh, float screenHeight) { var renderer = gameObject.AddComponent<MeshRenderer>(); var filter = gameObject.AddComponent<MeshFilter>(); filter.mesh = mesh; return new LOD(screenHeight, new Renderer[] { renderer }); } private Mesh SimplifyMesh(Mesh original, float reductionRatio) { // Integration with mesh simplification libraries // (e.g., SimplygonUnity, Weld3D, or QuadricMeshSimplifier) Mesh simplified = new Mesh(); // Implementation details... return simplified; } private Renderer CreateRenderer(Mesh mesh) { var renderer = gameObject.AddComponent<MeshRenderer>(); var filter = gameObject.AddComponent<MeshFilter>(); filter.mesh = mesh; return renderer; }}
Intelligent Texture Management and Atlas Packing
Automatic Texture Atlas Generation
Instead of managing dozens of individual textures, combine them into efficient atlases that reduce draw calls and improve cache coherency:
// Generated: TextureAtlasBuilder.csusing UnityEngine;using System.Collections.Generic;public class TextureAtlasBuilder : MonoBehaviour{ [System.Serializable] public class AtlasConfig { public int width = 2048; public int height = 2048; public TextureFormat format = TextureFormat.RGBA32; } public Dictionary<string, Rect> PackTexturesIntoAtlas( List<Texture2D> sourceTextures, AtlasConfig config) { // Sort by descending area (greedy bin packing) sourceTextures.Sort((a, b) => (b.width * b.height).CompareTo(a.width * a.height) ); Texture2D atlas = new Texture2D(config.width, config.height, config.format, false); Dictionary<string, Rect> uvMap = new Dictionary<string, Rect>(); int currentX = 0, currentY = 0, rowHeight = 0; foreach (var texture in sourceTextures) { // New row if texture doesn't fit if (currentX + texture.width > config.width) { currentX = 0; currentY += rowHeight; rowHeight = 0; } if (currentY + texture.height > config.height) { Debug.LogError("Atlas overflow. Increase size or reduce textures."); return null; } // Copy texture data to atlas Graphics.CopyTexture( texture, 0, 0, 0, 0, texture.width, texture.height, atlas, 0, 0, currentX, currentY ); // Record UV mapping Rect uvRect = new Rect( (float)currentX / config.width, (float)currentY / config.height, (float)texture.width / config.width, (float)texture.height / config.height ); uvMap[texture.name] = uvRect; currentX += texture.width; rowHeight = Mathf.Max(rowHeight, texture.height); } return uvMap; }}
Platform-Specific Resolution Optimization
Deploy different texture resolutions based on target platform capabilities:
// Generated: ResolutionOptimizer.csusing UnityEngine;public class ResolutionOptimizer : MonoBehaviour{ private static class PlatformTiers { public static (int width, int height, TextureFormat format) GetTier( RuntimePlatform platform) { return platform switch { // High-end: PC/Console (4K capable) RuntimePlatform.WindowsPlayer or RuntimePlatform.OSXPlayer or RuntimePlatform.WindowsEditor or RuntimePlatform.OSXEditor => (4096, 4096, TextureFormat.RGBA32), // Mid-range: Modern Android/iOS devices RuntimePlatform.Android or RuntimePlatform.IPhonePlayer => (2048, 2048, TextureFormat.RGBA32), // Budget: Older mobile (2-4 year old devices) RuntimePlatform.WebGLPlayer => (1024, 1024, TextureFormat.RGB24), _ => (2048, 2048, TextureFormat.RGBA32) }; } } public void OptimizeTexturesForPlatform(Texture2D[] textures) { var (targetWidth, targetHeight, format) = PlatformTiers.GetTier(Application.platform); foreach (var texture in textures) { // Resize using GPU for efficiency RenderTexture rt = RenderTexture.GetTemporary(targetWidth, targetHeight, 0); Graphics.Blit(texture, rt); // Readback and encode RenderTexture.active = rt; Texture2D resized = new Texture2D(targetWidth, targetHeight, format, false); resized.ReadPixels(new Rect(0, 0, targetWidth, targetHeight), 0, 0); resized.Apply(); RenderTexture.ReleaseTemporary(rt); // Save optimized texture byte[] encoded = resized.EncodeToPNG(); System.IO.File.WriteAllBytes($"{texture.name}_optimized.png", encoded); } }}
Streamlined Asset Bundle Building and Versioning
Complete Asset Bundle Build Pipeline
Antigravity orchestrates the entire bundle lifecycle—from dependency analysis to compression optimization:
// Generated: AssetBundlePipeline.csusing UnityEditor;using UnityEngine;using System.Collections.Generic;using System.Linq;public class AssetBundlePipeline{ [System.Serializable] public class BundleDefinition { public string name; public string[] assetPaths; public string[] dependencies; } public static void BuildAllBundles( BundleDefinition[] definitions, string outputDir, BuildTarget target) { // Configure bundle names foreach (var def in definitions) { foreach (var assetPath in def.assetPaths) { var importer = AssetImporter.GetAtPath(assetPath); importer.assetBundleName = def.name; } } // Build with compression var manifest = BuildPipeline.BuildAssetBundles( outputDir, BuildAssetBundleOptions.ChunkBasedCompression | BuildAssetBundleOptions.StrictMode, target ); // Log and validate LogBundleInfo(manifest, definitions); } private static void LogBundleInfo( AssetBundleManifest manifest, BundleDefinition[] definitions) { var bundleNames = manifest.GetAllAssetBundles(); Debug.Log($"Built {bundleNames.Length} asset bundles:"); foreach (var bundle in bundleNames) { var hash = manifest.GetAssetBundleHash(bundle); var deps = manifest.GetAllDependencies(bundle); Debug.Log($" {bundle}: hash={hash}, deps=[{string.Join(", ", deps)}]"); } }}
