even gimp can use a map with noise values. 
More more pliability, the best is to use https://www.shadertoy.com/ ;-)

<p>Recently, I want to use a roughness map to get better rendering results.<br />
Most information on the internet is about the operation of 3D software.</p>
<p>So, <strong>how can I generate a roughness map of my own 3D mesh?</strong></p>

I'm also considering generating a roughness map with Python, have you found a good method for it?
