What Is an Attribute Profile?

An Attribute Profile is a data asset that defines all attributes available on a character, including:
  • The list of Attribute Definitions
  • Starting values
  • Min/max
  • Regeneration settings
  • Progression rules
  • Level Link Definitions
  • Optional effect/calculation configuration
Every character using UMAS loads one profile at startup.

​
Profile Components

The profile consists of:

​
1. Attribute Definitions

The core list of attributes (Health, Stamina, Strength, Hunger, etc.) Rules like:
1 point of Strength → +5 MaxHealth
These are defined using the UAttributeLevelLinkDefinition asset.

​
3. Progression Config

Defines:
  • XP curves
  • Level curves
  • Attribute scaling per level

​
4. Modifier Rules

Defines the order and method in which modifiers apply.

​
Assigning a Profile

It is assigned inside the UAttributeManagerComponent: Field: AttributeProfile At runtime the manager loads all attributes, initializes them, and applies progression or link rules.

​
Designer Notes

  • Create separate profiles for different NPC types if needed.
  • For MMOs or RPGs, use multiple link definitions to organize logic.
  • Keep survival stats (Hunger, Thirst, Fatigue) in the same profile for simplicity.

​
Developer Notes

  • Profiles are read-only during runtime.
  • The Attribute Manager creates runtime instances using profile data.
  • You can generate profiles in C++ if needed.
