Asset Naming

These asset naming convention is a modified version of the Gamemakin Asset Conventions.

All asset names follow the basic syntax Prefix_BaseName_Variant_Counter_Suffix:

Part	Mandatory/Optional	Description
Prefix	mandatory	Type based prefix (see below)
BaseName	mandatory	Easily recognizable name that identifies the asset and related assets. This is usually what you would colloquially call the object (e.g. Sunflower, Bench, Rock, etc)
Variant	optional	Unique variants of the asset with a clear name (e.g. Diry, Clean, Broken, Glowing)
Counter	optional	If you have multiple assets with matching base name and variant or if you can’t reasonably find variant names, you can use a two digit counter. For consistency you should always use two digits. If you have more than 99 assets of the same type you should usually create other groupings instead of continuing to increase the counter.
Suffix	optional or mandatory	Type based suffix (see below)

Prefix and Suffix

Prefixes and suffixes are dependent of the asset type. Theoretically you could use no prefixes or suffixes as Unreal allows displaying and filtering the asset type without resorting to the file name, however this stops to work as soon as you’re dealing with raw file paths, assets on disk, in version control, etc.

Placing this crucial information at the same positions in the file name makes it easy to get an overview at a glance as well as making filter expressions (e.g. regex) for these files easier.
