PV Asset Validator is a Blender 4-5 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.

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 panelWorkflow-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 runIf you run into any issues or have questions, don’t hesitate to contact me.
