Breakdown

The body uses the same Markdown blocks as blog posts — see content/blogs/example-blog.md.

How it works

A noise texture is compared against a cutoff value; pixels below the cutoff are clipped and a thin colored edge is drawn where the two meet.

// Dissolve

float noise = tex2D(_NoiseTex, i.uv).r;
clip(noise - _Cutoff);
float edge = 1 - smoothstep(0.0, _EdgeWidth, noise - _Cutoff);
col.rgb = lerp(col.rgb, _EdgeColor.rgb, edge);
