@OP if you don’t want to redo the images - just go into the editor and copy all the nodes the (?) graph (if there are more than one, just copy and paste each separately), paste it here in a
tag and then everyone will be able to easily replicate the setup. (The nodes in the editors are copy/pastaed around via plain text in the clipboard - clever.) At least, that's the case with Blueprints and I think it should work the same with material nodes.
The nodes may end up being wrong due to referring to an asset that the person pasting them in doesn't have, but that's not a big deal as they can just fix it or make a new node of the same type and easily recreate it.
