This commit for external styles/shaders is great!
One question, and maybe you can do this already and I just couldn't find it, but is the following process possible?
Let's say you open an ifc file in BlenderBIM, and you're working away adding materials and tweaking shaders as you 'design'. Is there a way, currently, to automatically save these shaders out to that external library?
Or is the indented workflow to have (2) blender sessions open at open time. One for the working file, and one for the materials library. That is, you tweak shaders in materials library session, and then 'update' them somehow in the working file session?
