Just a quick question, I am thinking of doing the lerps tut, but I am wondering if I need unity pro or not, because I don’t want to download the file if it is just going to be a waste of time.
You do not need Unity pro.
In general you can run any project from Free/Trial that has been created with Pro. In most cases it’s about post processing which doesn’t interfere with the actual access to the project and/or script files. The project itself will “downgrade” and just not use those functions specific for Pro.
I’m guessing you’re at a bit of slow connection, i’d recommend finding a torrent of the project or 3rd-party downloading software which makes you able to resume your download if it’s interrupted.
