PV Asset Validator is a Blender add-on designed to help artists identify common asset issues before export to game engines, clients, or marketplaces.

Instead of manually checking assets under time pressure, the add-on provides a structured validation process that highlights potential problems early and helps maintain consistent asset quality across different pipelines.

PV Asset Validator focuses on practical, production-oriented checks and avoids destructive operations. It reports issues clearly and offers safe fixes only where automatic correction does not risk data loss.

What the add-on checks

• Object naming
  • User-defined naming rules (prefixes, suffixes, optional regex)
  • Naming conditions are set in Naming Rules
  • A highly flexible validation system. You can add conditions, exclude characters, and limit name lengths
  • Applies to objects, materials, UVs, and textures depending on the selection

• MeshData Name = Object Name
  • Check for consistency between Mesh Data Name and Object Name
  • If the names do not match, you can rename them using the ”Rename” button
  • This check can be disabled in Options

• Modifiers Presence
  • Check for assigned modifiers on the object
  • In the "Acceptable modifiers" list, you can select modifiers that will be excluded from the check

• Materials
  • Check for the number of materials. Set in Options
  • Material naming is set in the Naming rules
  • Presence of nodes and textures in the material

• Geometry checking
  • N-Gons. Faces with more than 4 vertices
  • Isolated vertices. Vertices that are not connected to any edge or face in the mesh
  • Overlapping vertices. Vertices at the same or nearly the same position without being merged
  • Flipped Faces. Faces with inverted normals
  • Custom Split Normals. Are custom vertex normals that override Blender’s automatically calculated normals

• Transforms
  • Check Scale for (1, 1, 1)
  • Rotation (0, 0, 0)
  • Ability to apply with a button in the validator

• Animation keys
  • Check for presence of animation keys
  • Ability to clear them

• UVs
  • Check the number of UV maps (set in Options)
  • UVs naming is set in the Naming rules panel
  • Check for UV coordinates within the 0–1 range

• Textures
  • Check for presence of textures in each material
  • Textures naming is set in the Naming Rules panel

Workflow-oriented design

• Validation runs on a fixed list of objects for stable, predictable results

• Clear validation list with direct links to problematic objects

• Optional Safe Fixes for selected issues

• Fully configurable validation options per run
