What have you tried, and what is “not happening”, and in what way? You have not said anything of what you did to try loading it through Unity so far. You should just be using the package manager like you would for other assets you get from the asset store.
Well I just tried it through the package manager and it all imports fine. Not “all there is is .json files” - it contains all of the package details as documented on the asset store page.
If you want us to help you, then you need to provide the steps you have tried to actually import the asset - which at the moment you don’t seem to want to tell us. All you keep saying is that things don’t work, but won’t explain what part of the asset loading isn’t actually working or even what step-by-step process you are trying (just saying “I tried the package manager…” is not really enough).
The asset imports with no problems, it even updates my project from 2019.3.x to 2021.4.x.
If you feel like telling us exactly the steps you are following, and which steps don’t seem to be working, then I am sure someone will be able to help you out.
There could be several reasons why “Open in Unity” isn’t working for you in Ubuntu 20.04. Here are some troubleshooting steps you can try:
Make sure you have Unity installed on your system. You can check this by running the following command in the terminal:
css
unity3d --version
If you don’t have Unity installed, you can download it from the official website: https://unity.com/.
Check if the Unity browser extension is installed and enabled. In Chrome, click the three dots in the top right corner and select “More Tools” > “Extensions”. Look for the Unity plugin and make sure it’s enabled.
Try disabling any ad blockers or extensions that may be interfering with the Unity plugin.
Clear your browser cache and cookies and try again.
If none of the above steps work, try downloading the asset manually and importing it into Unity. You can do this by downloading the asset from the website and then importing it into Unity by selecting “Assets” > “Import Package” > “Custom Package” in the Unity Editor.
If you’re still having issues, feel free to provide a screenshot and more details about the problem, and I’ll try to help you further.
