Shader — Xukmi Fx

The reflection of Elias on the screen stood up. It walked toward the glass.

vec3 hsv = vec3(hue, sat, val); vec3 color = hsv2rgb(hsv);

To use this shader, you can load it into any environment that supports GLSL (like Shadertoy, Processing with shaders, Three.js, or OpenFrameworks). Pass the u_time , u_resolution , and u_mouse uniforms. The result is a constantly morphing, colorful abstract “xukmi” visual.

"Your polygon count is too low, Elias," a voice whispered—not from the speakers, but from the air molecules vibrating around him.

float smoothMod(float a, float b) return floor(a / b) + smoothstep(0.0, 1.0, fract(a / b));

It wasn't a static image. It was a landscape, but not one drawn with polygons. It was a swirling, bioluminescent ocean of geometry that seemed to flow out of the monitor. The colors were hues Elias had never seen on a digital display—ultra-violets that felt warm, deep reds that tasted like iron. The reflection of Elias on the screen stood up

The shader was deceptively simple. It didn't rely on traditional rasterization. Instead, it used a recursive fractal algorithm that adapted to the viewer's subconscious expectations.

Unlike many shaders that rely on heavy external post-processing (like Reshade), Xukmi FX shaders are highly efficient, often usable even on mid-range hardware. Compatibility and Versions Pass the u_time , u_resolution , and u_mouse uniforms

The is a specialized visual enhancement mod primarily used within the Koikatsu (KK) and Koikatsu Sunshine (KKS) modding communities. It is often paired with the "Vanilla Plus" character shader to significantly improve scene lighting, post-processing, and material realism. Key Features and Usage

While many visual overhauls for the Koikatsu series focus solely on the background environment, Xukmi FX is built to enhance directly. It essentially recreates the game's vanilla shaders with vastly more control over lighting behavior. Key technical features include:
