No such program. I tried that, odf - working backwards - but that mess of nodes only made sense once I started applying the maths in formulas in the script and saw what nodes were generated. You do gain a very good understanding of nodal function by writing these scripts... shader tree node assembly kinda becomes a product rather than a process.

So, the maths behind the material is everything... the shader tree is just something that comes of it. Yeah, you can tweak it from there, but you want to be careful.
