Today, Unity released a new Long Term Support release and that’s pretty good news. This post explains Unity 2018.4LTS and SineSpace, and why it will matter for a long time to a number of content creators.
A Bit Of Background
Understanding how Unity version numbers work can be confusing for new users. Believe it or not, things used to be much more confusing. In April 2018, Unity streamlined things into two main release channels – TECH and LTS (or long term support). Click here to check out the announcement on the Unity blog.
In a nutshell, Unity uses a year dot major release dot minor release naming convention. They do three major releases a year in the TECH stream with a focus on adding features and improvements. Then after the first TECH release in the next year they put out an LTS (long term support) release for the previous year. The LTS release is a culmination of that year’s releases, and the focus is on stablity for long term support.
Ride The Wave Or Play It Safe
Some creators prefer to ‘ride the wave’ so to speak. They work with the latest releases to get access to new features and improvements as soon as possible. These users should follow the TECH stream (though you may want to check out this post regarding bleeding edges). Others prefer a more stable environment, and are looking for calmer waters. Content creators looking for maximum stability should stick with the LTS stream. As Unity explains it:
What they’ve done is taken Unity 2018.3.14f1 (released at the end of April), added a handful of additional patches and fixes (click here to read the release notes), and released that today as 2018.4.0f1. They will continue to support that with updates every couple weeks. However the focus is on patches and fixes that make 2018.4 even more stable and reliable.
How To Install Unity 2018.4LTS
The absolute best way to install and remove Unity versions is with the Unity Hub. I am a big fan of this tool – check out this post for more information on installing and using it.
Once you’ve installed and launched the Unity Hub, use the Installs tab. Click on the Add button at the upper right and choose that new version. The program will do all the dirty work of downloading, unpacking, and organizing everything, and then you should see something that looks like the image below.
Never Forget This Step
People always forget or skip this step because they’re in a hurry, but trust me this is important. You need to back up your Project. When you open it in a newer Unity version the project is updated, and there is no way to downgrade. If you run into serious problems and need to go back to a previous version, you will either need to restore your backup or manually rebuild your project. Most of the times things go smoothly, but when they don’t you will wish there was some easy way to get things back to how they were. Your backup is your safety net.
Updating Your SineSpace Project
This part is easy. On the Unity Hub’s Projects tab, you’ll see your list of projects along with the Unity version that it’s set to work with. Click on the disclosure triangle next to the Unity version, it’s circled in the image below.
When you click on the triangle, you’ll see a menu showing all the Unity versions installed on your machine (your list will probably be different than what’s pictured on mine below). Since you already installed 2018.4 in the step above, that version should be on your list.
Select it, then open your project normally. You should see a popup like the one below, asking you to confirm that you want to upgrade your project. If you made a backup, then it is safe to proceed. Just click the Confirm button and wait as Unity updates your project.
Reinstall the SineSpace Editor Pack
Once it finishes updating the project, you’ll be in your Unity Editor and ready for the second step. To get Unity 2018.4LTS and SineSpace working together, you will need to delete the SpacePack folder and then re-install the SineSpace Editor Pack. SineSpace 2018.3 and 2018.4 both use the Editor Pack for 2018.3 – so you can simply re-install the one you are currently using.
It might be worth taking a couple moments to check the SineSpace Discord and see if you’re using the latest version. Head on over to the #alphas or #betas channel and just download what you need (see the image below).
After you’ve downloaded or located your Editor Pack file to install, you need to delete the SpacePack folder from your project. To do that, simply go to your Project panel and locate the SpacePack folder. Select it, right click, and choose Delete.
One Final Note Before Installing
See this post on preserving your Project Settings – it will make your life much easier. Now you can install the Editor Pack using the Assets menu and choose Import Package -> Custom Package. Now just pick the file you just downloaded from Discord and install (don’t forget the step to preserve your project settings).
Mac Users Take Note – when I upgraded my project earlier, I discovered that I needed to re-install the Native Mac Uploader. It’s super simple – just click on the SineSpace menu and choose Tools -> Install -> Native Mac Uploader. It will take a few moments but everything is automatic and you will be all set to go.
You’ve made it to the end. You should now have Unity 2018.4LTS and SineSpace all ready to go. If you read my post about bleeding edges you should know that there are likely going to be some issues at first (click here to check out known issues on the SineSpace wiki), but in the weeks and months ahead they’ll be resolved and you should be able to enjoy an extremely stable ride with 2018.4LTS.
