Question by Jazzer008 · Jul 06, 2013 at 08:30 PM · shader random noise generate

Need some shader code translating to ShaderLab. Random float generation.

 float random( vec2 p ){
       const vec2 r = vec2(23.1406926327792690,2.6651441426902251);
       return fract( cos( mod( 123456789., 1e-7 + 256. * dot(p,r))));  
 }

I still very much learning Shader code and any help would be appreciated. Trying to output some random numbers within the shader to generate some noise for space skyboxes.

Sadly, apparently not many people know how to code shaders... $$anonymous$$y question about adding a bump map to an existing shader has gone unanswered for days, with plenty of views.
