Why Trellis 2 + Blender is the Perfect Combo
Trellis 2 generates stunning 3D models in seconds. Blender is the world's most powerful free 3D software. Together, they create a workflow that rivals expensive commercial pipelines.
This guide shows you exactly how to take a trellis-2 output and transform it into production-ready 3D assets using Blender.
Understanding Trellis 2 Output Formats
GLB/GLTF (Recommended for Blender)
What it is: Universal 3D format with embedded textures
Why use it:
- Single file with textures included
- Perfect import into Blender
- Works directly in web/Unity/Unreal
- Best balance of quality and compatibility
PLY (Gaussian Splatting)
What it is: Point cloud format for 3D Gaussians
Why use it:
- Advanced rendering techniques
- Real-time visualization
- Research applications
OBJ + MTL
What it is: Traditional mesh format with separate material file
Why use it:
- Legacy compatibility
- Separate texture control
- Simpler format
Step 1: Generate Your 3D Model in Trellis 2
Before importing to Blender, optimize your trellis-2 generation:
Recommended Settings for Blender Workflow
Resolution: 1024 (balances quality and performance)
Texture Size: 2048 (good for most uses, 4096 for hero assets)
Simplify: 0.95 (keeps detail, reduces mesh complexity)
Seed: Fixed value (for reproducibility)Export Settings
When exporting from trellis-2:
- Choose GLB format
- Enable embedded textures
- Set texture compression to none (edit in Blender later)
Step 2: Import GLB into Blender
Method A: File Menu Import
- Open Blender
File → Import → glTF 2.0 (.glb/.gltf)- Navigate to your file
- Click Import glTF 2.0
Method B: Drag and Drop
Simply drag the GLB file directly into Blender's 3D viewport.
Import Settings to Check
[Blender Import Options]
☑ Pack Images (embed textures in .blend)
☑ Merge Vertices (cleaner mesh)
☑ Shading: Smooth (better appearance)
☐ Guess Original Bind Pose (disable for static models)Step 3: Initial Cleanup in Blender
Check Scale
Trellis 2 models may import at unusual scales.
Quick Fix:
1. Select object (A to select all)
2. S + type "0.01" (scale down) or "100" (scale up)
3. Ctrl+A → Apply ScaleCenter Origin
1. Tab → Edit Mode
2. A (select all vertices)
3. Shift+S → Cursor to Selected
4. Tab → Object Mode
5. Object → Set Origin → Origin to 3D CursorCheck Normals
AI-generated meshes sometimes have flipped normals.
1. Tab → Edit Mode
2. Select all (A)
3. Shift+N (Recalculate Outside)
4. Or Mesh → Normals → Flip (if needed)Step 4: Mesh Optimization
Decimate for Games
Reduce polygon count while preserving shape:
1. Select object
2. Add Modifier → Decimate
3. Type: Collapse
4. Ratio: 0.5 (adjust as needed)
5. Apply when satisfiedTarget polycount guidelines:
- Mobile games: 1,000-5,000 tris
- PC games: 5,000-50,000 tris
- Film/rendering: Keep original
Remesh for Clean Topology
Create uniform quads for animation or sculpting:
1. Select object
2. Add Modifier → Remesh
3. Mode: Voxel
4. Voxel Size: 0.02-0.05 (adjust for detail)
5. ApplyManual Retopology (Pro)
For production assets, manual retopology gives best results:
- Use RetopoFlow addon (free)
- Create new mesh over trellis-2 output
- Build animation-friendly edge loops
Step 5: Texture Improvements
View and Edit Textures
1. Switch to Shading workspace
2. Select object
3. View material nodes
4. Locate Image Texture nodesUpscale Textures with AI
Use Stable Diffusion or Topaz to upscale:
- Export textures from Blender
- Upscale 2x-4x with AI
- Re-import to Blender
Bake New Textures
Create custom texture maps:
1. UV Unwrap your optimized mesh
2. Create new image for baking
3. Select high-res source, then low-res target
4. Bake → Diffuse/Normal/AOStep 6: Material Setup for Game Engines
PBR Material Workflow
Trellis 2 generates basic materials. Enhance for games:
Material Nodes Setup:
├── Base Color (from Trellis)
├── Roughness (create or extract)
├── Normal Map (bake from high-res)
├── Metallic (often 0 for organic)
└── AO (bake ambient occlusion)Export Materials for Unity
Export Settings:
├── Format: FBX
├── Include: Selected Objects
├── Path Mode: Copy (embeds textures)
└── Apply Modifiers: YesExport Materials for Unreal
Export Settings:
├── Format: FBX
├── Smoothing: Face
├── Include: Selected Objects
└── Apply Transform: YesCommon Workflows

Time: 15 minutes for 10 assetsTroubleshooting Common Issues
"Model looks black in Blender"
Cause: Material not connected or normals flipped
Solution:
1. Check material nodes are connected
2. Recalculate normals (Shift+N in Edit Mode)
3. Check for duplicate vertices (M → By Distance)"Textures missing after import"
Cause: External texture references broken
Solution:
1. Re-import with "Pack Images" enabled
2. Manually load textures to Image Texture nodes
3. File → External Data → Pack Resources"Model is too small/large"
Cause: Scale mismatch between tools
Solution:
1. Scale appropriately (S key)
2. Apply scale (Ctrl+A → Scale)
3. Check export settings match import"Export looks different than Blender"
Cause: Blender materials not game-compatible
Solution:
1. Use Principled BSDF shader
2. Bake all procedural elements to textures
3. Test export/import cycle before finalPro Tips for Trellis 2 + Blender
Batch Processing
Process multiple trellis-2 outputs efficiently:
# Blender Python Script for Batch Import
import bpy
import os
folder = "/path/to/trellis/outputs"
for f in os.listdir(folder):
if f.endswith('.glb'):
bpy.ops.import_scene.gltf(filepath=os.path.join(folder, f))Non-Destructive Workflow
Keep original trellis-2 mesh accessible:
- Duplicate original (Shift+D)
- Hide backup in collection
- Work on copy
- Reference original if needed
LOD Generation
Create multiple detail levels from one asset:
LOD0: Original Trellis 2 output
LOD1: Decimate 50%
LOD2: Decimate 75%
LOD3: Decimate 90%FAQ: Trellis 2 and Blender
What Blender version works best with Trellis 2 GLB files?
Blender 3.6+ is recommended. The latest LTS or stable release handles GLB imports well.
Can I animate Trellis 2 models in Blender?
Yes, but you'll likely need to:
