Need tool to create and export glsl shaders


I would like to use blender or anything else to visually create a GLSL shader and export the corresponding code to use it elsewhere.

Are there currently any -convenient- way to do it without writing them completely by hand?

My need spins around concrete and wood shaders.


AFAIK if exporting a simplee principeled shader this is exported in glb/gltf but to make one with nodes it might be better to use something like (quick search)

or any other node based GLSL shader tool ? This one seems to be aoutdated :??
