Hello, new to unity and here aswell. I am trying to bring our companies project template from 2018.2 to 2019.1 I had purchased a few assets(vegetation studio pro) that need specific packages that are located in the preview package section.(Burst,Collections,Mathematics,Postprocessing). My issue though is that we are on a secure network, no line to the outside world. I was able to create a new project in 2019.1 at my house, download the preview packages needed, and then put on my box. None of the 4 previous mentioned packages come over in the project. Inside the package manager, In project packages, I see them but they all have the same error. getaddrinfo EAI_AGAIN packages.unity.com443. It states that I seem to be offline, which of course, I am. Is there any way I can get these packages over to my box without having to get online?
