Basalt Panel UI Kit — single-framed panels and buttons

Low-poly drawn as rock rather than as a targeting overlay. The sci-fi sibling uses corner brackets and no continuous border, which reads as a heads-up display; this one closes the body completely, because a stone panel that is open at the corners reads as broken rather than as futuristic. The faceting is identical — four flat triangles meeting off-centre — and it is the palette and the closure that change the material.

Two nine-slice panels — a single-framed window frame with 8 px corners and a recessed inset frame with 6 px corners — cover almost every box a menu needs: dialogs, inventory grids, list backgrounds, tooltips and stat panels. A single continuous border keeps the panel quiet enough to sit behind dense text. Both stretch cleanly to any size because the corners never scale and the centre is a flat fill.

On top of the panels sit four square button states: default, hover, pressed and disabled. They are drawn on the same 120×44 base with 0 px corners, so you can swap the texture on a single button widget and get the whole interaction loop without moving a rectangle. The pressed state drops its face two pixels and removes the top highlight rather than just darkening, which is what makes a button feel clicked rather than merely recoloured.

Everything ships twice. The SVG sources are the files the kit was drawn in — open them, change the six ash grey tones or the single magma orange accent, and re-export. The PNG exports are flat, transparent and pre-scaled at 1x, 2x and 4x for engines that want bitmaps, with no premultiplied alpha and no baked-in shadow outside the sprite bounds.
