Create Metal Textures with Affinity Photo's Procedural Texture Filter

In this video, I demonstrate how to create metal textures using Affinity Photo's procedural texture filter.

Metal:
var v=vec2(rx*a/w,ry*a/w); var v2=vec2(perlincubic(v*d,o,s)); 2*i1*scerp(cellnoise2(v.x+t*dir(v2*c).x,v.y+t*dir(v2*c).y,b),perlincubic(v*d,o,s),e)+of

Perlin Bumps:
var sx=rx*a/w; var sxm=(rx-1)*a/w; var sxp=(rx+1)*a/w; var sy=ry*a/w; var sym=(ry-1)*a/w; var syp=(ry+1)*a/w; var vc1=vec3(r1,g1,b1); vc1*dot(debump((b*(mapcui(c,1,perlin(sxm,sy,6,d))-mapcui(c,1,perlin(sxp,sy,6,d)))+1)/2,(b*(mapcui(c,1,perlin(sx,sym,6,d))-mapcui(c,1,perlin(sx,syp,6,d)))+1)/2,1),v)
