I found an add-on that will fix all your UV problems in one click!

I had some problems with the dragon’s UVs, they always didn’t line up properly, and kept overlapping each other.
But then I found this great plugin: UV-Packer for Blender | UV-Packer that just does a great job on Pack UVs and is completely free!
This is not an advertisement or anything, I just found this plugin and it is absolutely amazing, and I believe it will help a lot of people!
Oh, its installation is a bit complicated for some reason, there is an explanation in the download.
