Best Practices and tips for UV Mapping?

Thanks for the reply

How do I go about doing this? and does this make my texture the same size in unreal? I’ve tried advanced UV normalizer (Advanced UV Normalizer | ScriptSpot) which is supposed to make the materials the same size, but I can’t seem to get it working right. I’m probably just being stupid, I know once I have done this once I’ll be able to do it a million times over again, it just getting the process down the first time.

I also saw this tool, looks handy.
