Workflow 2: Texture Generation Pipeline

GenesisCore + Dream Textures Combo

Phase 1 - Geometry (GenesisCore):
"Create a medieval castle wall section: 
- 10x5m stone wall with crenellations

Phase 2 - Materials (Dream Textures):
1. Select wall object → N-panel → Dream Textures
2. Generate: "weathered medieval stone wall, moss in cracks, seamless" 
   → Check Seamless → Generate → Apply
3. Select door → "aged oak wood, iron studs, seamless" → Apply
4. Select floor → "cobblestone pathway, worn, seamless" → Apply

Phase 3 - Polish (GenesisCore):
"Add vertex paint for moss variation on wall
Add geometry nodes for procedural ivy on top edges
Set up 3-point lighting for texture showcase"

Pure Dream Textures (Texture Projection)

1. Model base geometry (wall, floor, props)
2. Select all faces to texture
3. Enter Local View (/)
4. Dream Textures → Project Dream Texture
5. Prompt: "ancient dungeon corridor, stone bricks, torch lighting, moss"
6. Model: stabilityai/stable-diffusion-2-depth
7. Click Project Dream Texture
8. Adjusts UVs automatically

Workflow 4: AI 3D Generation + Cleanup

Hyper3D Rodin / Hunyuan3D

"Generate a fantasy creature concept:
1. Create Hyper3D job: 'dragon whelp, cute, stylized, low poly'
2. Poll status every 30s until complete
3. Import result
4. Cleanup:
   - Decimate modifier (ratio 0.3) for game-ready
   - Separate loose parts (P → By Loose Parts)
   - Create materials for each part (scales, eyes, horns)
   - UV unwrap (Smart UV Project)
   - Bake normal map from high-poly (if needed)
5. Rig: Add armature, auto-weight, basic pose"

---

Workflow 5: Procedural Generation with Geometry Nodes

City Block Generator

"Create Geometry Nodes setup for procedural city block:

1. Base grid: 10x10, 20m spacing
2. Building height: random 10-50m (seed controlled)
3. Building shape: extruded random polygons
4. Windows: array on faces, random offset
5. Roofs: flat/hipped/gabled (weighted random)
6. Street level: sidewalk, road markings, lamps
7. Variations: 
   - Park lots (empty with trees)
   - Plaza (fountain + benches)
   - Alleyways (dumpsters, fire escapes)

Controls exposed in modifier panel:
- Seed, Block Size, Density, Height Range, Style Mix"

Blender Python for Geo Nodes

# Execute via execute_blender_code
import bpy

ng = bpy.data.node_groups.new("CityBlock", 'GeometryNodeTree')
# ... build node tree programmatically ...
# See api/blender-api.md for Geometry Nodes API

Workflow 6: Animation & Rigging

Character Animation Pipeline

1. Import/Generate character (Mixamo, Hyper3D, manual)
2. Rigify:
   - Add Rigify meta-rig (Human)
   - Align bones to mesh
   - Generate rig
   - Parent with automatic weights
3. Animation:
   - Import motion capture (BVH/FBX)
   - Retarget to Rigify
   - Clean up: NLA strips, action layers
4. Export:
   - FBX for game engines
   - GLTF for web
   - Alembic for simulation cache

Camera Animation

"Create cinematic camera path:
1. Add Bezier curve for dolly path
2. Add camera, Follow Path constraint
3. Add Empty for target, Track To constraint
4. Animate curve evaluation (0-1 over frames)
5. Add DOF: focus on target Empty, f-stop 1.8
6. Motion blur: Cycles → 0.5 shutter, 16 samples"

Workflow 8: Batch Processing / Automation

Render Farm Setup

# Blender CLI rendering
blender -b scene.blend -E CYCLES -o //render/frame_#### -f 1..250

# Distributed (using Flamenco or custom)
# 1. Split frames across machines
# 2. Sync assets via shared storage
# 3. Collect output

Python Batch Script Template

# Run: blender -b -P batch_script.py

import bpy
import sys

def process_scene(scene_path, output_dir):
    bpy.ops.wm.open_mainfile(filepath=scene_path)
    
    scene = bpy.context.scene
    scene.render.filepath = output_dir
    scene.render.engine = 'CYCLES'
    scene.cycles.samples = 128
    
    bpy.ops.render.render(animation=True, write_still=False)
    bpy.ops.wm.quit_blender()

if __name__ == "__main__":
    # Args after --
    argv = sys.argv[sys.argv.index("--")+1:]
    process_scene(argv[0], argv[1])

---

Workflow 9: Version Control for .blend

Git LFS Setup

# .gitattributes
*.blend filter=lfs diff=lfs merge=lfs -text
*.png filter=lfs diff=lfs merge=lfs -text
*.jpg filter=lfs diff=lfs merge=lfs -text
*.hdr filter=lfs diff=lfs merge=lfs -text
*.exr filter=lfs diff=lfs merge=lfs -text
*.glb filter=lfs diff=lfs merge=lfs -text
*.gltf filter=lfs diff=lfs merge=lfs -text

# Initialize
git lfs install
git lfs track "*.blend" "*.png" "*.hdr" "*.exr" "*.glb"
git add .gitattributes

Blend File Diff

# Use blendfile-utils or custom script
# For meaningful diffs, export to interchange format:
blender -b scene.blend -P export_gltf.py
# Then diff .gltf (JSON)

Decision Matrix: Which Tool When?

Task	Primary Tool	Fallback
Quick geometry	GenesisCore chat	blender-mcp
Complex scene logic	blender-mcp + Codex/Claude	GenesisCore
Texture generation	Dream Textures	Poly Haven textures
Hero assets	Sketchfab / Hyper3D	Manual modeling
Background props	Poly Pizza	Poly Haven models
HDRI lighting	Poly Haven (both)	Poly Haven
Code automation	execute_blender_code	Geometry Nodes
Game assets	Dream Textures + Retopo	Substance Painter
Animation	Rigify + NLA	Manual keyframes
Batch render	CLI + Flamenco	Manual

Tips for Reliable Automation

1. Always verify before acting: get_scene_info → plan → execute
2. Use named objects: Explicit names > "the cube I just made"
3. Check mode: Ensure OBJECT mode before transforms
4. Apply scale: Ctrl+A → Scale before bevel/array/modifiers
5. Unique data: .copy() meshes when duplicating
6. Save incrementally: bpy.ops.wm.save_as_mainfile(filepath="scene_v001.blend")
7. Use collections: Organize by type (Geometry, Lights, Cameras, FX)
