Hi Elliott, This is a great breakdown and very generous in sharing your process and insights, you came a long way from the vending machine days!
Are you planning on releasing the UE4 project to the public? Or only builds? I'd love to play around with it in the editor if possible!
Create and arrange image frames in the film strip to piece together animations. You can import animated GIFs and PNGs; export animations as animated GIFs, QuickTime movies, or spritesheets!
Leverage Pixen’s wide array of tools when composing pixel art: Pencil, Eraser, Eyedropper, Zoom, Rectangular Selection, Magic Wand, Lasso, Move, Fill, Line, Rectangle, and Ellipse.
Take advantage of the flexibility layers provide when working with complex pixel art.
Add and organize commonly-used colors into palettes.
Define custom patterns to use while drawing with the Pencil, Line, or Eraser tool (instead of a single pixel).
Pick a flat, striped, or checkered background (or even a custom image) to be shown beneath the canvas.
Grid + Alignment Crosshair
Let the Grid and the Alignment Crosshair guide you in placing pixels just where you want them.
While editing at high zoom levels, use the Preview window to view the canvas scaled out; play back animations in the Preview window.
Left and Right Tools
Assign a different tool to the left and right mouse button. For example: pencil on the left; eraser on the right.
Pixen supports pressure-sensitive drawing tablets and maps pressure to color opacity.
Customize tool hotkeys to ease the transition from other image editors.
Work with all your favorite tools in full screen mode.
