Table A.1 (continued)

Index Error Error type Severity Solution

T11 Offset vertex order Technical Severe Correct vertex order with

custom code or start
over with new model

T12 Reversed normals Technical Serious Flip normals

T13 Transforms attached Technical Serious Delete transforms

T14 UV distortion Technical Serious Edit or reproject UVs

T15 Zero edge length face Technical Severe Delete face if possible, or

truncate affected part of
object

C01 Coincident faces Construction Moderate Delete or move affected

faces

C02 Coincident vertices Construction Minor Merge vertices if necessary

C03 Floating faces Construction Severe Delete

C04 Leftover geometry Construction Severe Delete

C05 Misaligned texture Construction Serious Edit UVs

C06 Origin offset Construction Serious Move to origin and delete

transforms

C07 Self-penetration Construction Moderate Edit face position and

orientation

C08 Separated faces Construction Serious Combine into same polyset

and merge

C09 Spikes Construction Severe Move to correct position or

delete and rebuild
affected faces

C10 UVs outside legal space Construction Serious Edit UVs

OP01 Excessive edge loops Optimization Minor Eliminate unnecessary edge

loops

OP02 History present Optimization Serious Delete history

OP03 Inconsistent vertex

resolution

Optimization Moderate Delete unnecessary vertices

OP04 Triangle count high Optimization Serious Delete unnecessary faces

OP05 Edge pattern confusing Optimization Moderate Adjust edge orientation ,

delete or add edges
where needed

OR01 Naming Organization Serious Rename objects

OR02 Grouping Organization Serious Regroup as needed

OR03 Layers unused/messy Organization Minor Fix names, assigned objects

as needed

OR04 Material assignments

inappropriate

Organization Moderate This is a face-level issue

where materials
assigned to incorrect
faces need to be
reassigned

OR05 Weak node chart order Organization Minor Reorder nodes
