No offense but I think I was the one who made it popular because I brought layering into tpt (I didnt make the first recognised layered save but i brought the tutorial). Also, I made it without the fourum tutorial. I thought, isnt phot and neut weightless? Is it possible that the save I saw was made this way? (the save I saw was yours) and I tried putting something under it, and I checked the thing that tells how many parts are in the save, and thus I learned how layered elements worked. Not to mention the fact that many people think that going into the fourums is too much of a hassle.
To be honest you are late, by months. The original inventors/discoverers of compression were bEngineer, sandstorm and myself. We did not ask for credit, I personally didn't care about credit, I cared about using it. When compression was removed I continued to use it in my saves, but mostly my stamps.
If you want credit for inventing layering then you should be giving credit to the original discoverers also. The fact is, pretty much nobody gives credit for using things, such as new technology to make smaller electronics.
