Auto fix Guide

Auto-fix Guide

A lot of what the validators find can be fixed with one click. The rest needs a person, either because the right answer is not obvious from the asset alone or because getting it wrong would cost you real work.

Warning: Without source control, some of these fixes cannot be taken back. Check the files out in Perforce, or commit what you have in Git, before you run a big batch.

What gets fixed automatically

A fixable row in the panel has a Fix button, showing the proposed value where there is one. From the Content Browser, right-click the asset and use Fix Issues, which lists the issue types found on your selection.

Naming: renames

The asset is renamed where it stands, and the engine leaves a redirector at the old path so nothing that references it breaks.

Rule	What the fix does
missing_prefix	Adds the correct prefix. Example: MyTexture → T_MyTexture. If the name would collide with an existing asset, a numeric suffix is appended.
duplicate_prefix	Removes the extra prefix. Example: BP_BP_MyActor → BP_MyActor.
missing_suffix	Appends the required suffix. Example: SC_Ambient (SoundConcurrency) → SC_Ambient_SC.
missing_allowed_suffix	Appends the first allowed suffix for the class. Example for World assets: L_Town → L_Town_P.
wrong_case	Capitalizes the first letter of each name segment after the prefix. Example: T_cross_fire → T_Cross_Fire.
junk_name	Strips the junk word and applies the correct prefix to what remains. Only fixes when a meaningful name part exists after the junk word. Example: New_BossEnemy → BP_BossEnemy.

Folder: moves

Rule	What the fix does
wrong_folder	Moves the asset to the best matching allowed folder under the current scan root. Example: a Material in /Game/Characters/ moves to /Game/Materials/. Creates redirectors at the old path.

Texture: property edits

These change the texture's import settings and save the asset.

Rule	What the fix does
texture_wrong_srgb	Sets the sRGB flag to the correct value for the detected texture type (on for color, off for data).
texture_wrong_compression	Sets CompressionSettings to the expected value for the texture type (e.g. TC_NormalMap for _N textures).
texture_wrong_group	Sets LODGroup to the expected LOD group for the texture type (e.g. TEXTUREGROUP_UI for _UI textures).

Mesh: property edit

Rule	What the fix does
mesh_nanite_policy	Enables or disables Nanite on the mesh according to the configured NanitePolicy. Saves the asset.

Asset Health

Rule	What the fix does
stale_redirector	Runs UE's Fix Up Redirectors on the redirector asset, the same thing you get by right-clicking it in the Content Browser and choosing Fix Up Redirectors. Deletes the redirector and updates all references to point to the new path.

Blueprint variable renames

Three of the Blueprint rules fix themselves by renaming the variable:

Rule	What the fix does
bp_bool_no_prefix	Adds b prefix to the boolean variable name. Example: IsAlive → bIsAlive.
bp_bool_is_pattern	Removes the redundant verb prefix. Example: bIsDead → bDead.
bp_var_not_pascal_case	Capitalizes the first letter of the variable name. Example: health → Health.

Warning: A variable rename updates every reference inside that same Blueprint. It does not touch other Blueprints or C++ that read the variable by name. Those you fix yourself, and the compiler will not always tell you.

Batch Fix

Clicking Fix on two hundred rows is not a plan. Batch Fix applies one rule's fix to everything currently visible in the panel, in one pass, with a review step first.

When it activates

The Fix All button in the panel toolbar becomes active when:

• All visible (filtered) results share exactly one Rule ID
• At least 2 of those results are auto-fixable

Use the rule filter dropdown to narrow results to a single rule, then click Fix All.

Conflict detection

Before the dialog opens, ASV scans for potential conflicts and marks affected rows:

• Name collision. Something with the target name is already sitting at the destination.
• Path collision. For a move, the destination folder already holds that asset.
• Unsaved changes. The package has edits that are not on disk yet. Save it first.

A row in conflict turns orange and its checkbox goes dead; hover it to see why. The whole check runs again right before anything is written, so a conflict that appears while you were reading the dialog still gets caught.

Dialog

The Batch Fix dialog shows all selected assets in a scrollable list:

• Results grouped by folder, and each folder header collapses
• Every row carries a checkbox, a status icon, the asset name with its full path on hover, the current value and the proposed one
• Search field to filter rows by asset name
• Select All / Deselect All buttons above the list
• Fix Selected stays disabled while nothing is ticked, and counts what is: Fix Selected (12)

Progress and result

Fixes apply one per frame. Each row updates its icon in real time (✓ = fixed, ✗ = failed). The button label tracks progress: Fixing… 12 / 47.

At the end you get a line in the dialog, Fixed 44 / 47, 3 skipped, and a toast. Closing the dialog refreshes the panel.

Undo

Undo behavior depends on the type of fix:

• Property fixes, meaning texture sRGB, compression, LOD group and Blueprint variable renames, all go into one UE transaction. One Ctrl+Z takes the whole batch back.
• Renames and moves touch the disk and do not undo with Ctrl+Z. The engine leaves a redirector at the old path, so references survive, but the rename itself stands. Source control is your undo here.

What requires manual fixing

Rule	Why no auto-fix	How to fix
name_pattern_mismatch	There is no single correct name here, and the tool cannot guess what you meant	Rename in Content Browser
non_ascii_name	Transliteration is locale-dependent	Rename to an ASCII name
folder_contains_unicode	Same reason. Renaming a folder moves everything inside it.	Rename folder
folder_not_pascal_case	Same	Rename folder
folder_disallowed_name	Correct target folder depends on project structure	Rename/reorganize folder
folder_in_developers	Decision where to move it requires human judgement	Move asset to production folder
texture_not_power_of_two	Requires reimport from source at correct size	Reimport texture at power-of-two dimensions
texture_exceeds_max_size	Requires reimport or texture editor change	Reduce texture dimensions in the source and reimport
bp_editable_missing_tooltip	A meaningful tooltip can't be generated	Add tooltip in Blueprint variable details
bp_editable_missing_range	Valid range depends on game logic	Set ClampMin/ClampMax in variable metadata
bp_var_config_flag	Removing Config may break runtime behavior	Remove Config flag from variable properties
bp_vars_uncategorized	Categories are project-specific	Add categories to editable variables in Blueprint
bp_var_atomic_type_name	New name depends on variable meaning	Rename variable (e.g. ScoreFloat → Score)
bp_var_redundant_context	Which part of the name to remove depends on intent	Rename variable to remove class context
var_array_not_plural	Pluralization rules are language-specific	Rename array variable to plural form
var_missing_type_name	Correct type suffix depends on variable purpose	Rename variable to include type (e.g. HitResult)
blueprint_compile_error	Error must be understood and fixed in Blueprint editor	Open Blueprint, fix compilation errors, save
blueprint_compile_warning	Somebody has to look at it in the Blueprint editor. Usually a deprecated node.	Open Blueprint, review compile warnings, save
mesh_no_collision	Collision type and shape depend on gameplay use	Add collision in Static Mesh Editor
mesh_no_lods	LOD settings depend on performance budget	Set up LODs in Static Mesh Editor or via auto-LOD
