Item Static Data Asset

Every item are constructed from a data asset, it's appearence (both in inventory and in game) and all relevant attributes which are static, is holded here. Such as: Mesh, weight, base price etc.

Using Inheritance in Data Assets

You can create new Data Asset Blueprints which your item instances could will from. For example a weapon class should hold its basic damage values, but armor items should hold its armor stats.

This way you can create a clean the data structre by only showing items relevant info, structure assets based on inheritance hierarchy, easily make changes via Property Matrix or make use Editor Utilities (which plug-in has some built in) while editing.
