Material library

So I got tons of materials migrating from one project to another, but I cant figure it out in witch one I have good fabric and where is metal, I had to open 5 projects to migrate materials to one and that is pain in the a… So is there library so I can easily drag and drop material in my project?! Or you have some other methods except migrating…

:frowning: so I have feeling its all around substance source and megascan… pay it if you want it or do it yourself…
