I am sure this is easy: how do you put all materials from the material edtior into a scene?
One by one works, but I haven't found a way to push all materials from the mat editor into a scene.

I need this after detaching and reataching a new file in file link manager.
Also, I would like to prepare a standard scene with all "standard materials" predefined and use this one on different projects/files.

Thanks
