Lumena makes creating Steam store art simple. All 9 required capsule sizes in one project, each with its own layer stack. Design once, export everything correctly sized.

Image, text, particle, light, and gradient layers. Group them into folders. 6 blend modes, opacity control, flip, resize, and multi-select operations.

30+ Real-Time Effects
Blur, sharpen, vignette, chromatic aberration, drop shadow, outer glow, inner shadow, stroke, halftone, oil paint, motion blur, posterize, color grading, and more. All stackable per layer.

Text Engine
