> using graphical programming (by connecting nodes) I use Octane Render [0] whose materials editor is based on graphically connecting nodes which might be materials (diffuse, specular, etc), image files, mappings, colours, procedurals, emitters and many more. Compared with conventional languages the Octane shader language lacks any sort of conditional or iterative constructs, which obviously simplifies the 'programming' required. I'm happy with graphical node editing for this shader use case. However, I sometimes really miss the ability to do a global textual search and replace across multiple materials, e.g. to change the file name of a normal map that is used in a node in multiple materials. I suspect that there would be similar frustrations when maintaining and updating a complex system configuration using a 'no-code' node-based mechanism.
