Overview

Early on, working with Unreal Engine packages can seem fairly straightforward; but as your project grows and you begin building out a lot of content, it can become difficult to manage all of the different asset types. Here is a breakdown of some best practices and suggestions for organizing content in your project.

Naming Conventions

It is recommended that content packages be organized in the following way:

Asset Type, Asset Name, Asset Sub Type (Used for Textures), LOD Level (used for MIPs, and mesh LODs)

Asset Type

Prefix	Asset Type
SK_	Skeletal Mesh
SM_	Static Mesh
SMF_	Static Mesh Fractured
M_	Material
AS_	Anim Set
AT_	Anim Tree
PA_	Physics Asset
MTS_	Morph Target Set
T_	Texture
PS_	Particle System
ST_	Speed Tree

Examples:

SK_Human
M_Human

Asset Sub-Type

Suffix	Asset Sub-Type
D	Diffuse
S	Spec
N	Normal
E	Emissive
M	RGB Mask For characters this is used for: * R = Spec Power Mask * G = Fresnel Mask * B = Transmission Mask For Hair: * R = Hair Alpha * G = Could be used for something on the body * B = Could be used for something on the body

Examples:

T_Human_D.tga
T_Human_N.tga
