Retro shaders in action. Affine Texture mapping on a surface shader and no sub-pixels.
Additive Color Mode. As documented on the PDF, the tool tints the objects with an stencil buffer value from 1 to 16 with a color in a palette.
Objects with a value of 0 in the stencil buffer act as background objects and the tool removes the color.
Solid Color Mode
A tool and shaders I created for adding accessibility modes and a retro touch that emulates the look of software rendering in the 90's for Bl0w-Up: https://llibertii.itch.io/bl0w-up.
