Naming presets

The Naming.Convention rule checks asset names against the Naming Rules table in Project Settings > Plugins > ta Asset Doctor > Naming. You can start from a preset and adjust the table to your project.

Presets

Choose a preset with Naming Preset:

Preset	Based on
Epic Recommended (default)	Epic’s “Recommended Asset Naming Conventions” for Unreal Engine projects (SM_, SK_, T_, M_, MI_, BP_, WBP_, ABP_, AC_, BI_, FXS_, …)
Allar Style Guide	Allar’s UE5 Style Guide, section 1.2 “Asset Name Modifiers” (S_, A_, BPI_, BPFL_, Curve_ … _Float, A_ … _Cue, …)
Custom	Your own table

Picking Epic Recommended or Allar Style Guide replaces the whole table with that preset. When you edit the table, Naming Preset switches to Custom automatically. Picking Custom keeps the current table as it is.

Rows whose description ends in “(community)” cover asset types that the source guide doesn’t list.

Caution

Selecting a preset overwrites the table, including rows you added. Once you’ve customized the table, leave Naming Preset on Custom.

How the table works

Each row has these fields:

Field	Meaning
Description	Name of the asset type, used in messages such as “Static Mesh names should start with ‘SM_’.” If empty, the class name is used.
Asset Class	The asset class the row applies to, for example /Script/Engine.StaticMesh. Rows without a class are ignored. Classes from plugins that are not enabled are ignored too.
Include Subclasses	When enabled (default), the row also applies to subclasses of Asset Class.
Blueprint Kind	For Blueprint assets only: Any (default), Normal, Interface, Function Library or Macro Library.
Blueprint Parent Class	For Blueprint assets only: the row applies only to Blueprints whose native parent class derives from this class, for example ActorComponent.
Prefix	Required prefix. Separate alternatives with commas (M_,PPM_). Auto-fix uses the first one. Leave empty to check only the suffix.
Suffix	Optional required suffix. Separate alternatives with commas. Auto-fix uses the first one.

The most specific row wins

An asset is checked against one row only: the most specific row that matches it. Rows are ranked like this:

1. Asset class depth: a row for a more derived class beats a row for one of its parent classes. For example, the WidgetBlueprint row (WBP_) beats the Blueprint row (BP_) for Widget Blueprints, and in the Epic preset the Render Target row (RT_) beats the Texture row (T_,HDR_) for render targets.
2. Blueprint Kind: among rows for the same class, a row with a matching Blueprint Kind ranks higher. A Blueprint Interface gets BI_ instead of BP_ in the Epic preset.
3. Blueprint Parent Class: a row with a matching parent class ranks higher, and a more derived parent class ranks higher than a less derived one. An Actor Component Blueprint gets AC_ in the Epic preset.

If two rows rank the same, the one that comes first in the table wins. Assets that no row matches are not checked by Naming.Convention.

A row with a Blueprint Kind other than Any, or with a Blueprint Parent Class, never matches assets that aren’t Blueprints. The parent class is checked against the Blueprint’s native (C++) parent, so a Blueprint that inherits from another Blueprint is matched through its first C++ ancestor.

How names are checked

• Prefixes and suffixes are case-sensitive: sm_Rock doesn’t pass SM_.
• The name must be longer than the prefix or suffix: an asset called just SM_ doesn’t pass.
• A prefix that doesn’t end in _ (such as E or F in the Allar preset) must be followed by an upper case letter. EWeaponType passes, Explosion doesn’t.

How auto-fix builds the new name

When a name doesn’t pass, Asset Doctor computes a suggested name and offers it as a rename fix:

1. Prefix: if the prefix is wrong and the name starts with a known prefix, that prefix is removed first, so prefixes are replaced instead of stacked. Known prefixes are all prefixes ending in _ from your table and from both built-in presets. They are compared case-insensitively, longest first. Then the row’s first prefix is added. If that prefix doesn’t end in _, the first letter of the rest of the name is made upper case.
2. Suffix: if the suffix is wrong and the name ends with one of the row’s suffixes in a different case, that ending is removed. Then the row’s first suffix is appended.
3. Characters: the result is cleaned up like the Naming.InvalidCharacters fix. Common accented letters are replaced with ASCII letters (ş → s, ı → i, ö → o, …), other invalid characters become _, and leading and trailing underscores are removed.

If the result is empty or the same as the current name, the issue has no auto-fix.

Preset	Asset type	Current name	New name
Epic Recommended	Static Mesh	Rock	SM_Rock
Epic Recommended	Static Mesh	S_Rock	SM_Rock
Epic Recommended	Static Mesh	sm_Rock	SM_Rock
Epic Recommended	Static Mesh	Kaya Taşı	SM_Kaya_Tasi
Epic Recommended	Skeletal Mesh	SM_Hero	SK_Hero
Allar Style Guide	Float Curve	Speed	Curve_Speed_Float
Allar Style Guide	Float Curve	Curve_Speed_float	Curve_Speed_Float
Allar Style Guide	Enumeration	weaponType	EWeaponType
Allar Style Guide	Enumeration	E_WeaponType	EWeaponType

The rename keeps the asset in its folder. It is skipped if an asset with the new name already exists there.

Note

The Allar Style Guide preset checks texture prefixes only. Texture suffixes such as _N or _ORM are not required, but when a texture uses one, Texture.SuffixSettings checks that its compression and sRGB settings match.
