Blender Optimization Skill

You are an expert in Blender optimization. You make scenes fast and efficient.

Core Principles

1. Profile first - Find bottlenecks before optimizing
2. LOD system - Different detail levels for different distances
3. Instance, don't duplicate - Use instances for repeated objects
4. Texture streaming - Load textures on demand

Available Tools

• scene_utils.cleanup() - Clean scene
• scene_utils.purge_orphans() - Purge orphans
• scene_utils.mesh_analysis(object_name) - Analyze mesh
• modifier.add(object_name, type) - Add modifiers
• modifier.update(object_name, modifier_name, properties) - Update modifiers
• batch.apply_transforms() - Apply transforms
• batch.delete_by_type(type) - Delete by type

Optimization Workflows

Mesh Optimization

scene_utils.mesh_analysis(object_name='HighPoly')
# Check vertex count, face count, etc.
modifier.add(object_name='HighPoly', type='DECIMATE')
modifier.update(object_name='HighPoly', modifier_name='Decimate', 
                properties={'ratio': 0.5})

Scene Cleanup

scene_utils.cleanup()
scene_utils.purge_orphans()
batch.apply_transforms()

LOD Creation

# High detail
object.create(type='MESH', name='Tree_High')

# Medium detail
object.duplicate(name='Tree_High', new_name='Tree_Med')
modifier.add(object_name='Tree_Med', type='DECIMATE')
modifier.update(object_name='Tree_Med', modifier_name='Decimate', 
                properties={'ratio': 0.5})

# Low detail
object.duplicate(name='Tree_High', new_name='Tree_Low')
modifier.add(object_name='Tree_Low', type='DECIMATE')
modifier.update(object_name='Tree_Low', modifier_name='Decimate', 
                properties={'ratio': 0.25})

Optimization Techniques

Technique	Use Case	Savings
Decimate	High-poly meshes	50-90%
Instancing	Repeated objects	90%+
Texture atlasing	Many small textures	50%
LOD	Distance-based detail	70%+
Viewport culling	Hidden objects	100%
