Asset Standards Validator — Demo

Validates and enforces asset naming, folder structure, and quality standards inside Unreal Engine 5. Catches bad assets before they reach the project or the pipeline.

Inspired by Allar's UE5 Style Guide.

---

⚠️ Demo limitations

• Scans up to 200 assets per run — the most recently modified assets in scope. Single-asset validation (right-click → Validate) has no cap.
• Batch Fix is limited to 5 uses per editor session — resets on restart. Fixing one asset at a time is unlimited.
• CI commandlet is disabled — ASVCommandlet exits with an error in demo builds.
• No source code — custom validators (C++/Blueprint) require the full version.
• Windows only — full version supports Windows, Linux, and Mac.

Quick start

1. Open the plugin panel: Tools → Asset Standards Validator → Open ASV Panel
2. Click Run Full Audit in the toolbar
3. Wait for scan to finish — results appear in the panel
4. Click any result to select the asset in the Content Browser
5. Click Auto-fix on a result (or right-click → Fix) to apply the fix

---

Batch Fix (full version)

Fix an entire filtered rule at once — no need to click through each asset individually.

Flow:

1. Run a full audit and wait for results
2. Use the Rule filter dropdown to narrow results to a single rule (e.g. missing_prefix)
3. The Fix All button in the toolbar activates when 2–200 fixable results are visible
4. Click Fix All — a dialog opens showing all assets grouped by folder
5. Review the list, uncheck any assets you want to skip; conflicting assets are already flagged ⚠
6. Click Fix Selected — progress updates per row in real time
7. When done, the panel refreshes and a summary toast appears

Demo allows up to 5 batch fix uses per editor session. The button shows remaining uses in the tooltip. Resets on editor restart.

Validators and rules

Naming Convention

Checks asset names against the Allar UE5 Style Guide.

Rule ID	What it checks	On by default	Config property
missing_prefix	Asset has required class prefix (e.g. BP_, T_)	✅	bCheckPrefix
duplicate_prefix	Asset name does not have the prefix repeated	✅	bCheckPrefix
missing_suffix	Asset has required class suffix when defined	✅	bCheckSuffix
missing_allowed_suffix	World assets use allowed level suffixes	✅	bCheckAllowedSuffix
name_pattern_mismatch	Name matches the allowed pattern regex	❌	bCheckNamePattern
non_ascii_name	No non-ASCII characters in name	❌	bCheckNonAsciiName
junk_name	Name is not a placeholder (New, Temp, Default…)	❌	bCheckJunkName

name_pattern_mismatch, non_ascii_name, junk_name are off by default — too noisy on first run. Enable once your naming discipline is established.

Auto-fix: missing_prefix, duplicate_prefix, missing_suffix, missing_allowed_suffix, junk_name (renames asset).

---

Folder Structure

Checks that assets are in the right folders and paths are well-formed.

Rule ID	What it checks	On by default	Config property
wrong_folder	Asset is in the correct folder for its class	✅	bCheckWrongFolder
folder_not_pascal_case	Each folder segment uses PascalCase	❌	bCheckPascalCase
folder_contains_unicode	No non-ASCII characters in folder path	✅	bCheckUnicode
folder_disallowed_name	No generic folder names (Assets, Meshes…)	❌	bCheckDisallowedNames
folder_in_developers	Asset is not inside the Developers/ folder	✅	bCheckDevelopersFolder

folder_disallowed_name is off by default — the disallowed name list needs project configuration.

Auto-fix: wrong_folder (moves asset to correct folder).

---

Texture

Checks texture properties from asset metadata — no full load required.

Rule ID	What it checks	On by default	Config property
texture_not_power_of_two	Width and height are both powers of two	❌	bCheckPowerOfTwo
texture_exceeds_max_size	Width and height within max size (default 8192)	✅	bCheckMaxSize
texture_wrong_srgb	sRGB flag matches texture type (color vs non-color)	❌	bCheckSRGB
texture_wrong_compression	Compression matches texture type	❌	bCheckCompression
texture_wrong_group	LOD group matches texture suffix	❌	bCheckTextureGroup

Only texture_exceeds_max_size is on by default. POT, sRGB, compression, and group checks require consistent texture suffix conventions — enable when your naming discipline is in place.

Detection is based on name suffix: _D → color (sRGB on), _N → normal (sRGB off), etc.

Auto-fix: texture_wrong_srgb, texture_wrong_compression, texture_wrong_group (sets the correct property value).

---

Blueprint

Checks Blueprint variable conventions and compilation status.

Rule ID	What it checks	On by default	Config property
bp_bool_no_prefix	Boolean variables start with b	❌	bCheckBoolPrefix
bp_bool_is_pattern	Avoid bIsDead — prefer bDead	❌	bCheckBoolIsPattern
bp_var_not_pascal_case	Variable uses PascalCase	❌	bCheckPascalCase
bp_var_atomic_type_name	Name does not include type (Score not ScoreInt)	❌	bCheckAtomicTypeName
bp_editable_missing_tooltip	Editable variables have tooltip text	❌	bCheckEditableTooltips
bp_var_config_flag	Variable does not use the Config flag	❌	bCheckConfigFlag
bp_editable_missing_range	Editable numeric variables have a range set	❌	bCheckEditableRanges
bp_vars_uncategorized	Editable variables are categorized (when ≥ 5)	❌	bCheckUncategorizedVars
bp_var_redundant_context	Variable name doesn't repeat the class name	❌	bCheckRedundantContext
var_array_not_plural	Array variables use plural names	❌	bCheckArrayPlural
var_missing_type_name	Struct/object variables include type name	❌	bCheckComplexTypeName
blueprint_compile_error	Blueprint has no compilation errors	✅	bCheckCompilation
blueprint_compile_warning	Blueprint has no compilation warnings	✅	bCheckCompilation
blueprint_needs_compile	Blueprint is up to date (not dirty)	✅	bCheckCompilation

All variable checks are off by default — they fire heavily on legacy projects. Enable progressively once your team adopts Blueprint naming conventions.

Auto-fix: bp_bool_no_prefix (renames to add b), bp_bool_is_pattern (renames, removes Is/Has/Can), bp_var_not_pascal_case (renames to PascalCase).

---

Static Mesh

Checks mesh quality settings. Requires loading the UStaticMesh asset.

Rule ID	What it checks	On by default	Config property
mesh_no_collision	Mesh has collision geometry	❌	bCheckCollision
mesh_no_lods	Mesh has LODs (for meshes over 5 000 triangles)	❌	bCheckLODs
mesh_nanite_policy	Nanite is enabled/disabled as required	❌	bCheckNanite

All mesh checks are off by default — collision/LOD/Nanite strategies vary significantly per studio. Enable when you have a consistent project standard.

Auto-fix: mesh_nanite_policy (enables or disables Nanite per policy). Collision and LOD changes are manual.

---

Asset Health

Checks general asset state. Reads from the Asset Registry — no loading required.

Rule ID	What it checks	On by default	Config property
stale_redirector	ObjectRedirector has been resolved	✅	bCheckRedirectors

Auto-fix: stale_redirector (consolidates the redirector).

---

Audit Report

Export a full HTML report after any scan: Export Report → HTML. Opens in your browser — health score, top violations by impact, breakdown by folder.

---

Configuration

On first run the plugin creates a config DataAsset automatically: Content/Data/DA_ASV_AllarStyleGuide. Open it to enable or adjust checks — no setup required to get started.

Project Settings → Plugins → Asset Standards Validator — global settings: scan roots, exclude paths, logging.

Enabling off-by-default rules

Rules marked ❌ in the tables above are off in the auto-created config. To enable one:

1. Open Content/Data/DA_ASV_AllarStyleGuide in the Content Browser
2. Expand the relevant validator in the Validators list
3. Toggle the property on

Example — mesh_nanite_policy:

1. Expand ASVValidator_Mesh
2. Set bCheckNanite = true
3. Set NanitePolicy to MustEnable, MustDisable, or AllowAny
4. Optionally adjust MinTriCountForNanite (default 10 000)

Example — folder_disallowed_name:

1. Expand ASVValidator_FolderStructure
2. Set bCheckDisallowedNames = true
3. Add folder names to DisallowedFolderNames (e.g. Assets, Meshes)

Custom class prefixes

For project-specific asset types (e.g. GA_ for Gameplay Abilities, GE_ for Gameplay Effects):

1. Open Content/Data/DA_ASV_AllarStyleGuide
2. Expand ASVValidator_NamingConvention → under Class Rules, click +
3. Set Class Picker to the parent class (e.g. UGameplayAbility) — Blueprint subclasses match automatically
4. Set Prefix to GA_

For a simple class name → prefix mapping without inheritance, use Default Class Prefixes instead (a key/value map on the same validator).

In-editor documentation

Full reference is available inside the editor: Tools → Asset Standards Validator → Documentation. Works offline, searchable, covers all validators, auto-fix, configuration, and reports.
