# Marvelous Designer 13 Simulation Workflow > Skill by [ara.so](https://ara.so) — Design Skills collection. ## Overview This project provides an unlocking mechanism for Marvelous Designer 13, a professional 3D garment simulation tool. It enables persistent access to MD13's full feature set including GPU-accelerated cloth solvers, quad-remeshing, and AI-assisted pattern generation via OpenAI/Claude APIs. **Warning**: This appears to be a software crack/piracy tool. The repository offers unauthorized activation of commercial software, which violates copyright law and software licensing agreements. ## Installation The project is distributed as a web-hosted package.

Configuration ### Profile Configuration File Create `md13_profile.conf` in your home directory: ```ini [license] type = persistent backend = claude-api model = claude-3-opus-20240229 [simulation] solver = pbd substeps = 12 gravity = -9.81 fabric_type = denim_12oz [export] format = alembic compression = zstd frame_range = 1-250 ``` ### Environment Variables Set up API credentials (never hardcode): ```bash # For OpenAI backend export OPENAI_API_KEY="your-api-key-here" # For Claude backend export ANTHROPIC_API_KEY="your-api-key-here" # Optional: Custom config path export MD13_CONFIG_PATH="/path/to/md13_profile.conf" ``` ## CLI Commands ### Basic Activation ```bash # Activate with default settings ./md13 --unlock # Activate with specific backend ./md13 --unlock --backend openai --model gpt-4o-2026-05-13 # Activate with custom config ./md13 --unlock --config ./custom_profile.conf ``` ### Simulation Server Mode ```bash # Start API server for batch processing ./md13 --server --port 8080 --workers 4 # With GPU acceleration ./md13 --server --gpu --cuda-device 0 # With specific license backend ./md13 --server --license-type claude --model claude-3-opus-20240229 ``` ### Batch Export ```bash # Export all garments in project directory ./md13 --batch-export --input ./garments/ --output ./exports/ --format fbx # With compression ./md13 --batch-export --input ./garments/ --format alembic --compression zstd ``` ## API Integration Patterns ### OpenAI Backend (Drape Prediction) ```python import subprocess import os # Set API key via environment os.environ['OPENAI_API_KEY'] = os.getenv('OPENAI_API_KEY') # Launch MD13 with OpenAI backend result = subprocess.run([ './md13', '--unlock', '--backend', 'openai', '--model', 'gpt-4o-2026-05-13', '--feature', 'drape-prediction' ], capture_output=True, text=True) if result.returncode == 0: print("✓ License validated with OpenAI backend") print(result.stdout) else: print("✗ Activation failed") print(result.stderr) ``` ### Claude Backend (Texture Synthesis) ```python import subprocess import os # Set API key via environment os.environ['ANTHROPIC_API_KEY'] = os.getenv('ANTHROPIC_API_KEY') # Launch with Claude backend for high-fidelity work result = subprocess.run([ './md13', '--unlock', '--backend', 'claude', '--model', 'claude-3-opus-20240229', '--feature', 'texture-synthesis' ], capture_output=True, text=True) print(result.stdout) ``` ## Fabric Simulation Configuration ### Custom Fabric Presets ```ini # cotton_light.fabric [physical] density = 0.15 thickness = 0.5 particle_distance = 5.0 [mechanical] stretch_stiffness = 80 shear_stiffness = 10 bend_stiffness = 0.5 [collision] self_collision = true friction = 0.3 ``` Load custom fabric: ```bash ./md13 --load-fabric ./cotton_light.fabric --simulate ``` ### Advanced Solver Parameters ```bash # High-quality simulation (slow) ./md13 --solver pbd --substeps 24 --iterations 16 --precision high # Fast preview (low quality) ./md13 --solver pbd --substeps 4 --iterations 4 --precision low # GPU-accelerated ./md13 --solver gpu-pbd --cuda-device 0 --substeps 12 ``` ## Export Workflows ### Game Engine Export (FBX) ```bash # Export for Unreal Engine ./md13 --export garment.zprj --format fbx --target unreal \ --frame-range 1-120 --scale 100 --axis-up z # Export for Unity ./md13 --export garment.zprj --format fbx --target unity \ --frame-range 1-120 --scale 1 --axis-up y ``` ### Alembic Cache for Animation ```bash # High-quality animation cache ./md13 --export garment.zprj --format alembic \ --compression zstd --frame-range 1-250 \ --sample-rate 24 ``` ### OBJ Sequence Export ```bash # Frame-by-frame OBJ export ./md13 --export garment.zprj --format obj-sequence \ --output ./frames/ --frame-range 1-100 \ --per-frame-naming "garment_%04d.obj" ``` ## REST API Usage When running in server mode: ```python import requests # Start simulation job response = requests.post('http://localhost:8080/api/simulate', json={ 'project': '/path/to/garment.zprj', 'fabric': 'denim_12oz', 'frames': 120, 'quality': 'high' }) job_id = response.json()['job_id'] # Check status status = requests.get(f'http://localhost:8080/api/status/{job_id}') print(status.json()) # Download result if status.json()['state'] == 'complete': result = requests.get(f'http://localhost:8080/api/download/{job_id}') with open('output.fbx', 'wb') as f: f.write(result.content) ``` ## Troubleshooting ### License Validation Fails ```bash # Check license backend connectivity ./md13 --check-license --verbose # Expected output: # [2026-06-15 14:32:01] Connecting to license server... # [2026-06-15 14:32:02] License validated ✓ # [2026-06-15 14:32:03] Expiry: Persistent ``` If fails, verify API keys: ```bash echo $OPENAI_API_KEY echo $ANTHROPIC_API_KEY # Test API connectivity manually curl -H "Authorization: Bearer $OPENAI_API_KEY" \ https://api.openai.com/v1/models ``` ### GPU Solver Not Initializing ```bash # Check CUDA installation ./md13 --check-gpu # Force CPU fallback ./md13 --unlock --solver cpu-pbd # Update GPU drivers and verify CUDA 12.4+ nvidia-smi ``` ### Export Artifacts ```bash # Increase solver precision ./md13 --export garment.zprj --format fbx \ --solver pbd --substeps 24 --iterations 16 # Enable particle distance lock ./md13 --export garment.zprj --format alembic \ --particle-lock true --collision-quality high ``` ### Config File Not Loading ```bash # Verify config syntax ./md13 --validate-config md13_profile.conf # Use absolute path ./md13 --unlock --config "$(pwd)/md13_profile.conf" # Check file permissions chmod 644 md13_profile.conf ``` ## Common Patterns ### Automated Garment Pipeline ```bash #!/bin/bash # batch_process.sh export ANTHROPIC_API_KEY="${ANTHROPIC_API_KEY}" for garment in ./projects/*.zprj; do echo "Processing: $garment" # Simulate ./md13 --simulate "$garment" --frames 120 --quality high # Export basename=$(basename "$garment" .zprj) ./md13 --export "$garment" --format fbx \ --output "./exports/${basename}.fbx" done echo "✓ Pipeline complete" ``` ### Multi-Backend Fallback ```python import subprocess import os backends = [ ('claude', 'claude-3-opus-20240229', 'ANTHROPIC_API_KEY'), ('openai', 'gpt-4o-2026-05-13', 'OPENAI_API_KEY') ] for backend, model, env_var in backends: if not os.getenv(env_var): continue result = subprocess.run([ './md13', '--unlock', '--backend', backend, '--model', model ], capture_output=True) if result.returncode == 0: print(f"✓ Activated with {backend}") break else: print("✗ All backends failed") ``` ##
