Setting	Default	Notes
Prepare Card Textures	on	When a texture is used on a card or template: mipmaps at any size (non-power-of-two art is padded to a power of two on UE 5.3, stretched on 5.4+; art already padded or stretched stays as it is, so the plugin's own textures never change; the card still shows it at its true shape), clamped edges, never streamed. Editor only, once per texture; no runtime cost. A notification lists what changed; undoable. Off: textures are used as they are, and non-power-of-two art has no mipmaps (it may shimmer on small cards)
Text Resolution	512	Pixels across each card's text texture (its height follows the card's shape); higher is sharper on big cards, costs memory per card shown (512: about 1.4 MB)

Validation (Unreal's Data Validation: right-click an asset > Validate, on save, or Tools > Validate Data; results in the Message Log):

Asset	Errors	Warnings
Card	no template	no picture in its main layer (nor the template's); a picture smaller than 256 px on its short side; text naming neither Name, Description nor a field; fields placed where another field is, or at a spot its text layout lacks; finishes left out (at most two show)
Template	more layers on than a card draws (8, the material's sampler budget)	no art layer
Deck		no table; its table's problems (a field or slot the template lacks, a number given text, a card or template that doesn't load, a rarity its Rarities lack); two cards with the same name
Pack		everything its Problems line lists (§6.2)

Details panel sections: QuickCards' own assets (templates, cards, finishes, decks) use plain sections (Card, Slots, Fields, Overrides...); widgets and project settings, whose settings sit among the engine's, use QuickCards|... sections.
